The 7S Bashing Revolution Is HERE! 6S Can't Compete!

[@KevinTalbotTV]

why not just run 8s? more power and you can use 2 4s lipos.

[@Chon-c]

It’s about weight as he said . More power at the same weight as 6 s.

[@chrisjarvis83]

@@Chon-cI whole Hearted Agree!!!!!!!

[@DoRC]

You definitely can though running two lipos in a vehicle design for one can sometimes be challenging because the battery tray isn't made for it. Ultimately though this was intended to showcase how running higher voltages is better so to be honest the higher the voltage the better within reason as it's just going to keep getting more and more efficient and lighter. It is important to keep in mind though that the higher you go with the stock motor the more likely it is you're going to over rev it and kill it.

Discharging in minutes vs hours is a game changer! Agree if SMC made 7s hard shells or with the g10 plates all around those would be a no brainer with all the max6 builds out there. Amazing video as always, you’re putting that notorious through the wringer!

[@DoRC]

Yeah I think I finally broke it too. The center differential has a tight spot. It's not the gear I think I might have actually damaged a bearing which would be impressive

[@timh5653]

The tip about the self tapping screw threads is fantastic. Just a couple times not doing that and the hole can strip out. Great for Tamiya kits that use a lot of self tappers.

[@DoRC]

Absolutely. Especially with older plastics it's really nice to be able to just use the same threads over.

[@Wanderingpyro]

I found this out the hard way about capacitors holding a charge. Taught me a lot about electricity. Like don't f*** around unless you know exactly what you were doing. I was taking apart a ceiling light and it had a little transformer looking thing in it when I went and touched it to take it off the light and shocked the s*** out of me

[@DoRC]

Yeah they can hold a charge for quite a while and can be deadly.

[@n00b247]

7s are nice and all but imho most will stick to 2x2s cos 2s are cheap and simple and easy.

[@DoRC]

I think most people are going to single batteries these days. There really isn't a lot of advantage to running dual batteries and like I said at the end of the video the primary problem right now with higher voltage systems is just that people aren't using them so the demand is low causing the prices to be high. Given that running higher voltages is advantageous for power and weight I think people should really start looking at it. The more we do it the more manufacturers might notice and then once we start getting some mainstream 7s vehicles out there things will get a lot cheaper

[@V8chump]

I feel like most RCs are designed to use two batteries…. I feel like running one 7s would either kill my runtime because it still had to fit in the single battery tray…. I could get 10000mah on 6s dual battery tray or fit one 4000 mah 7s 🤔🤔🤔

[@Boogie_the_cat]

​@@V8chumpI use a single battery in all my RCs. Even the ones with a dual battery tray, I use the second tray to store my 2nd 6s battery, so I can just plug that in when the first battery runs out. 2 batteries are a hassle, I cut off the second XT90 because it's a nuisance. Do whatever makes YOU happy though, that's what the hobby is about. If someone likes wearing rubber gloves on their feet instead of socks, I'm not going to tell them it's wrong.

[@3Y3ECE]

@@DoRC I agree about the single battery statement, as I'm guilty myself. Any platform I get for dual battery goes single, unless there is a spot on both sides of the chassis for a battery. The weight distribution needs to be correct, even for bashers, as you know well. So for me, a 7s system would probably need to be centralized, as the motor/esc/servo/receiver side probably still wont weigh what a beastly 7s does! But, there are other ways, and that's the point. Streamlining rc's will only lead to better, more efficient rc's! Great video! Want that charger now!

[@Chon-c]

@@DoRC. Hobbywing max 6 will do 7s too. I’ve been seeing more makers of these odd cells. It is a better idea to go to 7s than running 8 because of the weight. Two big batteries doesn’t double the run time by doubling the Mah when both are being drawn from. Besides. Most batteries are lying about true mah & especially the C RATING people buys batteries STRICTLY BECAUSE OF lol. Most of them are only like 40 c. I don’t care if it says 100 on the wrapping . Lol. People gets mad when you tell them this. But it’s 100% correct.

[@Xjeepguy]

I bought that charger recently, and its definitely next level. Ive been giving some thought to running my Kagama 7s, so your video came at the right time. I think it needs to happen. Great vid as always, thanks!

[@Macgyver46]

You're pushing for higher voltage, and I'm over here loving 4S instead of 6S 😂 for city bashing.

[@DoRC]

Yeah it's kind of accomplishing two different goals. Classically higher voltages have been used and associated with more power but it doesn't have to be that way. A higher voltage system can be used to generate the same amount of power while being smaller lighter more efficient and cheaper. That's kind of what I'm advocating for here. Our modern managers don't really need more power per se but making them lighter more efficient and cheaper definitely is a good thing.

[@332_RC]

Awesome video! Thanks for the in depth info on the charger & the possibilities of running 6s or 7s if someone wanted to on their RC. Definitely a consideration for bashing & speed runs!

[@RC_CARnage]

In regards to the VHB tape, Two things If people are having issues with their VHB 1.) 3m recommends rubbing the tape with your finger to warm it up, and running your finger nail across it, to "activate" the adhesive before removing the film. 2.) They also make a primer you can use on the surface you wanna stick the tape too, however that is more of a permanent solution, and will make removing whatever you stick down that much more difficult, and depending on the surface almost impossible without damage Also, if youve ever heard of the "silicone lottery" in regards to great performing CPUs, im curious if i won the motor & ESC lottery with my Notorious V5, because ive seen people complain about the v5s lack of power, but my v5 on 6s acts the same way your v6 did on 7s.

[@DoRC]

I think it depends. If you're running stock gearing The V5 will behave the same under initial acceleration just because it has more mechanical advantage. With the 16 tooth pinion the V6 is a lot faster on the top end but gives up some of that bottom end which is restored on 7S.

[@surfside75]

I see what you've done here and it's good.. I've kept a simple formula, all my 3s get 150a esc to run on 4s. 6s get a 160a esc to run 8s. Stock motors work no issues just fan em.

[@DoRC]

Nothing wrong with that. The nice thing about 7S is that you can still run it single battery and you're pretty much guaranteed that the 6s motor won't blow up. 6s motors on 8S usually are okay but they can get over revved.

[@KiloWattRC]

for the simple fact that most esc's can only technically detect even number of cells to properly enable LVC. Not to mention 1 extra cell doesn't add much weight. If your motor is rated for 7s max voltage then this makes sense.

[@DoRC]

Well to be fair ESCs that can't handle five or seven s only can't do it because they haven't been programmed to do so. Castle ESC's can therefore electronically any ESC can. It's not really the weight of the extra cell that is the benefit It's the reduced size of wiring potentially smaller ESC smaller motor etc.

[@KiloWattRC]

@DoRC yup you can most definitely pull out a calculator and apply the voltage your want LVC to kick in at, just not so practical as auto LVC what most people run

[@RoostedFilms]

Politely, More trouble than it's worth for most. I really appreciate the deep dive.

[@DoRC]

I agree that for the end user upgrading to 7S right now probably doesn't make sense in most cases which is kind of what I was addressing at the end of the video. This video was more to ask me for having higher voltage systems in our vehicles in general then it was to get viewers to do a specific thing.

[@MCsCreations]

Awesome mod, dude! And thanks for the review of the charger! 😃 Now the truck has what we call "turtle mode" in the FPV world... Basically, you don't need to do the walk of shame when it rolls over! 😂 Anyway, stay safe there with your family! 🖖😊

Self righting has actually been around for quite a while and is a built-in feature of some Traxxas trucks. If you don't do it right it can be hard on the drivetrain though.

[@justonjacoby4455]

I get what your say about the 7S as in weight and less mass in wiring!! I wish that charger was a 8S lipo charger!! Being able to charge 2 8S lipos at that wattage would be amazing...GREAT VIDEO ON EXPLAINING THE CHARGER & 7S!

[@DoRC]

Yeah I think it is a little interesting that they went with 7S and not 8S. I suspect it was a limitation of some sort of hardware inside the charger itself but maybe not.

[@Sabbath-666]

For an AC charger that's pretty powerful and certainly worth a look if you're after one. I still don't think you can beat iChargers though :)

[@DoRC]

If you have the money and the space the I chargers are fantastic. They're just really expensive and really clunky

[@Maseehullah786]

I'm curious... With all that extra weight... Shouldn't you tighten up the shock springs ?

[@DoRC]

It's not that much heavier than a stock one but yeah you would want to tighten them up if you found you were bottoming out too much. This one still feels pretty good to me

[@GreatLakesRC]

7s is interesting for sure 👍 it’s similar to using 5S in 4s vehicles, I have done that and it works quite well.

[@DoRC]

Yes same idea. The higher the voltage of the better.

[@rogueFactor]

5S and 7S power has been underrated for at least a decade. this episode deserves to be in the national archives.

[@DoRC]

I agree. I think we should be looking toward higher voltages in everything we run. There's no reason we shouldn't be running 6s systems in cars that are currently running 3S or 8S in 6s cars etc. Smaller lighter more efficient systems are awesome!

[@Djkommode]

@@DoRCthen do 8s for even more energy? Why stop at 7?

[@DoRC]

@@Djkommode I completely agree. The higher the voltage the better but 7S is a good jump up from 6S as an upgrade because you can do it without really having to worry about blowing up your motor.

[@WowoodogPlays]

Some companies should come out with 7s trucks

[@DoRC]

Yeah in order for that to be widespread adoption of running higher voltages like this it's going to have to come from manufacturers.

[@FelipeFabris-bc7kv]

I think the reason for 7 and 5s being underrated is because in theory its better to just go for 8s, but 8s needs much bigger and heavier components, and the diference between 8s to 7s is quite small, good in reallity, bad in theory, i never thought it would be so good, Thanks for the video!

[@DoRC]

Yeah the higher you go in voltage the smaller the jump between cell counts is. 3S to 4S is a big jump but 7S to 8S is not very much.

[@cj910]

[@jc49fishniner4lif7]

Like always great info ,one question do you think we can make lipo batteries back to life bcuz I have some 3s batteries that have one of the cells too low and it doesn't take any charging

[@DoRC]

Unfortunately no. Once the cells drop below a certain voltage around 2.8 volts internal cell damage occurs. You can't fix that damage and you can't test for it. On top of that the cell dropped for a reason and it's probably because that cell is going bad. You really don't want to mess with lipo batteries that are going bad because that's how lipo fires happen.

[@Boogie_the_cat]

​@@DoRCexcellent advice. I'd rather buy a new battery than a new house. I've seen a lipo fire in person, and I know people who've had their garage burn down. Lipos are cheap enough compared to the other option.

Unfortunately it is a loud fan. There's opportunity to do something like 3D print and adapter and mount 120 mm fan on the outside or something like that but unfortunately the internal fan is 70 mm which is a really unusual size so there are limited options for just replacing it.

[@DoRC]

Maybe though I'm pretty sure that this system is limited more by the motor than the ESC and I've run similar setups before. The stock ESC has quite a bit of jam and I'm confident that the increase in power was primarily the increase in voltage.

[@RainbowRoadsRc]

something I've been wondering is if you can charge gtech or other smart batteries on non smart chargers?

[@DoRC]

You can charge the gtech ones because they designed it to where the balance lead is just a standard balance lead with the extra pin on the outside. The G1 spectrum smart batteries can also be charged on the standard charger but the G2 spectrum batteries and Traxxas batteries can't because they don't have any sort of external balance connection.

[@Mark-yy2vw]

So i just run a max 6 in all my 6s cars, run 2 4s 5000mah gens ace to keep the weight down ,run 70% throttle and a low punch setting, works for me

How long did those batteries last in the XRT?

[@DoRC]

Run time is one of those things that's really subjective and depends on a million different factors. I think I got about 35 minutes out of them but that is no indication what you would get out of yours. I will say that they are quality packs and are about the biggest batteries you can reasonably fit in the XRT so if you want long run time they are a decent option.

[@keldonator]

@DoRC Thanks. Yea maybe the 9200mah would be good enough for me. Free shipping at $200 though so I was considering those 10200mah or the 11400mah but the 10200 are a bit too thick for the stock tray.

[@sub-sonicwavescaraudio1814]

I think I got like 35 minutes but run time is highly subjective and what I got is almost certain to not be what you'd get. That being said these batteries are high quality and about the largest batteries that'll fit in the truck so if you're looking for extended runtime these are a good option

[@toksta79]

I'll save you the energy. Adding extra cell to the lipo for higher voltage will be significantly heavier than the weight savings in electronic components being smaller. Plenty of power with 6s without sacrificing strength to weight.

[@DoRC]

Not really. The additional weight of the extra cell would be made up for by the ampacity being lower. You'd have the same energy out of the battery (in watt hours) and the weight would be basically be the same.

[@broderp]

Me....just getting started on 2S.....😂

[@reallythough4591]

You can go a long way on 2s. Get into drag cars, that's one heck of a rabbit hole. Just picked up a system that gives me over 100k rpm on 2s. It's gonna be ridiculous.

[@DoRC]

There's nothing wrong with that. As long as you're having fun you're doing it right!

[@johanneswicklein4975]

I think 7s might be better suited for a Kraton since it can keep the power better to the ground. For me 6s is more than enough already. I bought a good namebrand 6800mah 6s lipo for my kraton, just to limit the trottle to 80% since it is too fast for me already😂😂 But the interesting thing I see here is standardization. Maybe in a few years time, we will run everything on 12s, from 1/18 to 1/5 scale. Only lipo size and power output of the esc and motor will change.

[@DoRC]

Yeah this was more to advocate for running higher voltages in general rather than recommending putting this particular system in this particular car. This was just what I had at hand that's a recent release.

[@elizabethmcheffey8699]

Did you say the run time on the XRT? I get +/-35 mins out of 11300 in my OC8s. I’ve never seen the 11400 pack

[@DoRC]

I didn't because run time is such a subjective thing that whatever I said would be wrong for 90% of other people even with the exact same setup. Package what you have on your car how much your car weighs you're bashing style The temperature out how tall the grass is etc etc will all affect run time so I find it's best just not to talk about it as most of the time I just ends up with a bunch of people who don't understand why they all are getting different run times :-)

I've always been wondering why RC cars run on such low voltages and ridiculously high currents. It puts a lot of strain on the electronics and wiring. This is the reason powerlines have such high voltage. Low voltage and high current would lose a lot of power over long distance by heating the wires.

[@DoRC]

Yeah with the shorter distances in RC cars it's not quite as bad but higher voltages definitely are more efficient.

[@ArnoldKrT]

is it more safe to charge a battery with 5800 mah to 5.0 amps? or must be 5.8?

[@orbitaljellyfish808]

So to run 4s on 3s rated components without overheating the motor would need “the same” amount of power (wattage at the motor) to be governed by some other means than the motor’s inherent limitations; like a throttle trim? I would assume that, apples to +apples-trim, the higher voltage setup would give better burst and long term wattage delivery In addition most over-powered setups can’t use all the power without losing control anyway, so if you’re running throttle trim to keep it on the ground it might just work for insane power across the whole run. At least in winter 😂

[@DoRC]

Yes the more power the motor is converting the warmer it's going to get but ultimately the goal would be to have these vehicles coming from the factory running higher voltages so that the systems could be tuned and sized correctly out of the box.

[@speckledjim_]

Always wondered why 5s wasn't more popular, for me it really is the sweet spot between 4&6s, more capable and powerful than 4s but much better handling at speed than 6s

[@DoRC]

I think those odd number cells never really became popular because when higher voltage RCs started coming out four and 6s batteries really didn't exist so everybody was using two 2s batteries and two 3s batteries. These days other than a lack of availability there really is no reason not to be using 5S and 7S

[@feverexplosion1968]

I have the D300 and I am charging my 7600mah 6s lipo. Why does it charge it than less than 1c? Is that bad for the battery?

[@DoRC]

The d300 is a 300 watt total charger but I believe it can only do 150 Watts per channel. In order to charge that battery at 1C you need more than 150 watts. No charging it below 1C is not going to hurt the battery as a matter of fact some people believe the slower you charge the battery the better it is for it. So ultimately it's just going to be slower.

[@RC4us]

i REALLY need a charger that does 8s that isnt expensive and i think i need a power supply any budget ideas

[@DoRC]

I think your best bet if you want to go with a single 8S pack is an iCharger. Unfortunately I don't think there are any inexpensive 8S capable chargers out there

[@RC4us]

@ yeah I've found some but then I need a power supply and I'm so confused on that end of it

[@DoRC]

@RC4us basically you just need a power supply that outputs the amount of Watts that you need the charger to be able to output plus a little bit more. I think the input voltage requirements would be in the manual for the charger and if you have any questions I charger can probably give you some guidance.

[@RC4us]

@ so you mean like my rdx2 800 would need a power supply that can push 800watts I could be thinking wrong

[@DoRC]

@RC4us You're thinking is correct though we need to be a little bit more than 800 Watts as in order to get 800 w out you need to put more than 800 Watts in due to electronic conversion losses. How much more I'm not entirely sure but a thousand Watts would probably cover it. You also probably don't want to be pushing the power supply to its absolute limit all the time anyway. The other consideration is voltage. Some chargers have a minimum 24 or even higher voltage requirement to get full output power which can make getting power supplies for them a lot more difficult.

As long as you're using a good quality charger and the battery is in good shape it should balance just fine as it should have started out almost perfectly balanced from the last charge. As far as why it's a matter of convenience. When I want to go bash I want to go bash I don't want to wait hours for my batteries to charge and then go bash.

[@jayepps8646]

@ fyi you’re a bad influence! I really trust your opinion i like your style of explanation your a good teacher i appreciate your channel very much , i buy many of the vehicles you approved of hehe

[@OGRCFanatic]

Yea this is just pointless. Sorry if that comes off as negative or rude. But, if you want more than 6s, drive an 8s. If you want less than 8s, drive 6s. I mean 7s? Seriously? Who cares about a little extra weight of an 8s. This is a hobby, not life and death racing competitions.

[@DoRC]

So there are some advantages to upgrading to 7S. The first one is that you're less likely to damage a motor only going up one cell rather than two. The second one is fitting a single 7S battery into a 6S vehicle is a lot easier than two 4S packs. Ultimately though this wasn't really intended to Tell people that they specifically should be upgrading to 7S. It was more to advocate for running higher voltage in general. I do kind of explain this at the end of the video. To be fair though 7S really isn't that ridiculous it's just not really done much So it seems that way. It's just as valid of a cell count as any other cell count.

[@OGRCFanatic]

@ yea, but although I respect your opinion on this, I just don’t see the point. You’ll probably never even notice any real difference in one cell. I respect your opinion. You think it’s something worth doing, I feel it’s a waste of time and money, and a lot of trouble for very little reward. If I want more speed than my 6s notorious will give me, I’ll drive my XRT 🤷🏻‍♂️ Still interesting content, though. I just personally don’t see any benefits to doing this.

[@christopherzatalokin8652]

That esc really woke that truck up.

[@DoRC]

It definitely is stout.

[@whitenas]

50 amps is mind blowing for rc battery charger. And at $260 pretty dam reasonable. I was expecting $500

[@DoRC]

Yeah it's by no means cheap but the specs definitely justify the cost at least to me.

[@rccrazy]

The worst thing about 5s and 7s is basically zero escs recognise 5-7s without setting them to NIMH. Cars like that dont need more than a decent 6s system and that's saying something coming from me😅

[@DoRC]

It's not really a matter of whether or not the car needs it. This wasn't primarily an increasing your power video This was primarily to advocate for the efficiency benefits of higher voltage systems. Fortunately most castle ESCs will recognize odd numbered cells and any ESC has the capability of it they're just not programmed to. If more people started using them more ESCs would start supporting them.

[@Boogie_the_cat]

I excitedly bought a 5s battery but my Max 8 recognizes it as a 6s battery that is nearly depleted. In general I'm more thrifty than lazy, but I don't feel like manually telling the ESC (thru Bluetooth app) that I'm running 5s and then changing it back each time i run 5s, so the new battery sits in the corner, crying. I think for this 7s thing to catch on, more manufacturers aside from Castle need to reprogram their ESC firmware to recognize odd numbers aside from 3s. I recognize the value of your idea, but someone needs to send Hobbywing a memo. They're a little "slow" if you get my drift. 😮😂

[@DoRC]

Do you have a Max 8G2?

[@WickeD72]

The castle esc alone would have changed the way the truck drove.

[@DoRC]

I'm not sure. The latest version of the stock ESC is really good and it's primarily motor limited now. I drove the car off camera on 6S with the castle ESC and it wasn't really that much different. That being said the goal of the video wasn't really to make my particular car significantly more powerful The goal of the video was to advocate for running higher voltage systems in RC due to the increased efficiency of those systems.

[@MemelordJord]

That explains why my Grandpa’s tool box smelled like puke

[@DoRC]

Yep.

[@PigglyWigglyDeluxe]

I’m also wondering why people are not using 12S more often in speed run cars. If max5g2 had better data logging, people would forget about XLX2 entirely

[@DoRC]

I think you hit the nail on the head. With 8S power the XLX2 is still more powerful than the max 5 G2 on 12S power. As soon as we see an ESC that has more jam on 12S everybody will be running 12S.

[@boduke9428]

​@@DoRC you think that Mad Max 20 esc is our huckleberry? It sure seemed pretty powerful on the kilowatt rc channel pushing that 8s Kraton to 100+ mph on 12s.

[@DoRC]

@boduke9428 definitely seems like a pretty nice ESC.

[@nitrosix6six]

You say more power same weight but how can you add a cell to a battery and not add to it's weight?

[@DoRC]

For the same amount of total energy in the battery you would have a lower per cell capacity so the weight would essentially end up the same. You would have slightly increased weight due to the additional foil wrapper on the outside of the extra cell and a little bit for the tabs connecting the cells but that would be pretty negligible.

[@MichaelJones-ok4yu]

Craftsman tools have a lifetime warranty. I think Lowe’s is the main distributor since Sears is dead. I would call Lowe’s customer service before heading to Lowe’s bc they may prefer you mail it in instead of the original method of swapping it out at Sears (RIP to Sears Roebuck & Company)

[@DoRC]

I would do that but this has sentimental value.

[@pierzus1]

This is amazing 😮❤

[@Chon-c]

I got an older Dynamite Charger. It can do 1 to 8s and charge up to 10c and 100 watt per channel (4) They quit selling these ol chargers because they are so versatile & they could sell lesser chargers for more $. Mine was only 150$ when I got it.

[@DoRC]

Not bad. These days 100 watts per channel is pretty limiting but there are definitely worse stats out there.

[@nitrosix6six]

You could also use a 8s single and an 8s charger.🤷

[@DoRC]

Absolutely. The point of the video is more the concept of running higher voltages rather than specifically 7S. 7s was just what this charger can do and a nice sweet spot upgrade from success that doesn't risk blowing up your motor.

[@Gosha_kloynyara]

This chrage costs as my car

[@DoRC]

Yeah it's definitely not cheap. I'm hoping that manufacturers will start putting higher voltage systems in their cars which will then create more demand for these types of chargers and drive down price

[@brendancurtin252]

[@ChrisRing-r2i]

I personally find 6s to be the sweet spot my notorious is a monster with jconcepts magmas tire if ya haven't tried em yet ya missing out

[@DoRC]

Yeah these things have plenty of power on 6s. The goal of the video was more to showcase that we should be running higher voltage systems in our cars not necessarily that we need more power in our cars

[@toolbaggers]

Would 5s be the ultimate upgrade for a 4s basher?

[@DoRC]

5S or maybe even 6s. The reality is that we're only really limited in voltage by what we're willing to do. Higher voltage systems are always going to be more efficient and always going to be lighter so it really makes sense to go with the highest voltage we can get away with.

[@BroJogan-fy7pm]

All new batteries? All new charger. for ONE extra S, naw i'll pass cool video tho love the channel!

[@DoRC]

Yeah this wasn't as much to convince people to do what I did. It's more of a conceptual video showing that we all should be pushing to run higher voltage systems in all of our cars. If manufacturers would start putting higher voltage systems in cars they could be made lighter and more efficient and ultimately cheaper.

[@freyjaslittlejeeps1602]

Where do you get the VM 3HB? (yes, I know, I'm being a smartass) The individual power supplies is interesting. My ancient 4 button chargers both had their AC power supplies blown up by an idiot (me) charging 6s packs at 5a. Oops. Since they still worked on the DC side, I just plugged them into a 12v30@ industrial power supply, and they've worked fine for 15 years. A couple of weeks ago, I opened one up and discovered that the AC power supply is just a generic laptop brick with the output soldered to the board, so I took that out to save weight or something. Then I destroyed one charger using a cheap connector that I didn't know was cheap.

[@DoRC]

I buy mine on Amazon. Yeah I have found from the power chargers I have taken apart that all of them pretty much run an independent power supply. I guess this makes sense especially for chargers that can run off DC as the power supplying and the charging systems really are two separate things.

[@freyjaslittlejeeps1602]

@@DoRC I'm shopping for power supplies again, which I hate almost as much as shopping for cars, houses, and doctors. I blame you :P This time I'm just going to rule out AC chargers entirely, since the power supply adds quite a bit to the price.

@@DoRC I'll check them out! :D The only thing I miss about the NiMH and NiCd days are building my own chargers. Even if there was a chip out there that could handle everything, and there is, I just don't trust Li batteries enough for DIY chargers.

[@DoRC]

@freyjaslittlejeeps1602 I think that's a reasonable way to feel. It doesn't take much for a charger to blow up a battery if it's not working properly.

I don’t know about clunky AND expensive. My charger setup has been a 40 PSU and $30 ISDT Q6 nano chargers. Those chargers go up to 8s. But it is only 200W at 24v and the psu I have is 12v

[@DoRC]

Nice! I was not aware of this particular charger. The vast majority of charges out there only go up to 6S but it's good to see that more options are becoming available! That's what we need in order to encourage higher voltage systems in our cars.

[@dylanwhite6539]

@@DoRCI love the Q6 nano chargers. Been using them for about 4 years now. They’re not the easiest control scheme but if you can get used to it they work very well and are so dirt cheap you can pretty easily afford to buy many to give each battery its own charger instead of parallel or series charging. Though I have expanded so much that I’ve started to series charge a couple packs with the 5 chargers I have setup. I also plan on upgrading to a 24v psu at some point.
