Everything You Need To Know About RC Car LiPo Batteries - Holmes Hobbies

[@Cannabis_Connoisseur]

Another note. You are getting way better at making videos sir. I already know plenty about lipos, BUT I still enjoyed watching the whole video. That's a testament to the quality of content your now making sir. You've entertained me enough to keep watching even though I already know the info. Please keep the awesome videos coming.

[@traviselliott3042]

love it when you get technical, your passion really shows through! Thanks!

[@RadonManRC]

Great amount of information! Thank you!

[@ryandavis9507]

I run a gens aces 4300 3's and love them super super long run times. & use them in heavy trail trucks/rock crawlers.

[@BandAid350z]

I’ve also been happy with those batteries. Not bad bang for the buck.

[@ryandavis9507]

Nope there not definitely good batteries for how long they last.

[@rc-daily]

I'm so glad you touched on the liars on the c rating. Traxxas is probably the only honest company. If you look at all of their batteries they're only 20-25c. Which is where most batteries actually are. None of them 50c 75c and definitely not 100c.

[@kajex1rc351]

Excellent info brother! the other channels were so confusing, thanks for sharing your experience over the years.

[@paulschryer9571]

- great info John, thanks !! 😉

[@evandautrich972]

Been running cnhl batteries in my drag car and crawler for a year. Just picked up some 1300 3s 100c from their black series. Have been great so far

[@Lithium023]

I was impatient and bought the traxxas 4s 6700mah Batts and duel charger live kit from my hobby shop for my xmaxx. I was going to get a charger and Batts from Amazon but couldn't wait. Anyway I have been really happy with the traxxas set up tbh, it is pricey for sure but I got 51min run time on my first charge with them. That to me is amazing and generally I'm just done with driving it now before the Batts even run out. The charger has storage mode that I use every time after I'm done driving it and the charger charges the battery's to full in about 40 to 45 mins wich is perfect. The app is very useful for seeing how well your cells are balancing aswell which is nice. All in all really happy with everything.

Love your videos man, The cool Bill Nuy the Science guy of RCs.

[@TRKISH324]

I run 3s 3000mah Zees for my crawling, atm. In my Spawn and for trailing my Gen 8 I run 5000mah 3s Goldbats, soft pack as well

[@BBC.Customs.2]

Been running Lectron Pro 3S 5200mah packs for years and love them

[@timothypimlott7641]

On nicad nmh battery's balance charging was never used but on discharge the check was on each cellist you got an expensive discharger. Good info for all thanks

[@wesmadebuilds681]

For a comp, I run 850mah 3S. For trail running I run the biggest I can fit in the truck. Typically in the 2200mah range. I will also run 2s on trail where it’s not a lot of complicated terrain.

[@humanx187]

I love this series!

[@familyrc6689]

The traxxas chargers can be used to balance charge other batteries, there is a balance port behind the traxxas logo on the front.

[@HolmesHobbies]

Ah ha! they just pop right off! awesome!

[@patrikmoller3643]

Great video, I'm going to bookmark this to share to all the new guys who start asking about batteries :)

[@Jlemus01]

Not a crawler but a Trail runner 2021 Trx-4 Bronco here 7000mah 3s 120c lcg battery tray works perfect 👌

[@RC-ll1rt]

Great info , there's a lot to learn about lipos and how to care for them

[@durden.tyler537]

I prefer to run 5000mAh NiMH with a laydown battery tray between the front shock towers. The weight and low tray yield a great front weight bias for climbing and stability. The lack of low voltage cut off in the ESC gives a long runtime. Most of all, batteries are stored fully charged so I’m always ready to run in seconds.

[@zonegamma8197]

i use lipo but you are right about the simplicity and safety of NiMH i hope the next step in tech will be the best of both lipo and NiMH

[@IowaBudgetRCBashers]

Thanks for the explanation

[@brianonthego]

Question. What do you use to run your batteries down to 3.3 volts, then know when to stop? Do you use a plug in cell checker on board? I run mine until no forward movement.

[@HolmesHobbies]

the escs have an adjustable low voltage cutoff

[@mbarton98]

A good multiport charger was the best thing I got so that I could put a set of four batteries at a storage voltage after a session of using them. I likely would not do that if I could only do one battery at a time.

[@themountain59]

One more guy here who runs CNHL lipos...they are the best bang for the buck!

[@whatalias]

I run mainly 1300 or 2200 3s spektrum batteries.

[@brianonthego]

3s 1500 lipo, shorty pack with xt60 plug. My favorite in my scx10 ii.

[@PhilBender612]

Traxas cells do go up to 4 cells... their plug can accommodate balance leeds for 4 cells.This is how they use 8s systems. It Does work with a their universal plug, kind of hard to explain, check out a picture of a traxas 4 cell. Great job explaining lipos Jon.

[@HolmesHobbies]

Ahh, I see the molding has room for a few more pins. My system was the 2 to 3s only one.

[@ed0c]

i stop at 3.5 on all my packs, i would rather carry extra packs in my bag. have to correct you on the size issue though, if its a graphene battery it throws the numbers off for the size. i highly recommend spectrum chargers/batteries. you pay for it, but amazingly safe.

[@mikeshobbiesandrandomstuff]

Excellent content John I always enjoy your work. Have you seen the bat-safe lipo storage box yet? I got one and love it already it's way safer than the useless cheap bags we grew up with.

[@KEVLAR_RC7275]

I've been running Ovanics 3s 3000mah on the Gen8. They work pretty good.

[@emory442]

I've read that the Internal Resistance of the pack will tell a lot about its quality. Any chance of you touching on that in the future?

[@Cannabis_Connoisseur]

Goldbat 3s 1500mah 100c. Super cheap on Amazon and usually get them within two days. Had tons all very strong and make it multiple years. Don't no that there actually 100c like they advertise but I do know they have way more punch than either of my traxxas 3s 5000mah batteries.

[@ryurc3033]

I usually run a 3000mah 3s ovonic, or a 2200mah 3s in the front of my trx4( and just carry a spare). I have had the ovonic for 2 years and they are both a bit puffy. Turnegy 2200 did good, going on 3 years. Been trying zee lately in my bashers lately, and have one that has held up to a 2s drag car with a 4.5 turn motor and a mamba x. Doesn't drop off voltage as much in the data log, like some other 2s I have tried. However I'm going to have to get 2 more small 3s so may be trying something new. I put xt60s on everything. Just as overkill

[@BandAid350z]

Gene Aces and Zees have been doing okay for me. Glad to see that others have similar reports. Makes me feel better in my choices.

[@Greywolf74]

Im curious why you switched from Deans to XT60s and were you using genuine Deans or generic ones?

[@Zzxii]

Love your videos. As someone familiar with batteries and all the terminology, solid review. To be honest though I would not recomend this video to a new person/beginner. Its a little all over the place.

[@justanothercanuck4660]

I’m upgrading my Trail finder 2 after 10 years absent from the hobby . The hobby sure has changed . I’m going to run a firma that the esc has a 6 volt 3 amp built in bec . How many accessories can I run on it . 7.4 v high torque servo and a 6 volt light kit . My winch is rated for 12.6 volts so good there. What bec would you recommend ?

[@Redneckrc]

I run a dynamite 2s 5000mah short pack on my Vaterra ascender, gonna run the same battery when I switch to a 13.5t brushless system

[@mbarton98]

I’m still running on my old Wraith 2.2 the Hobby People 2200mAh 3s 65c batteries.

[@wesmadebuilds681]

What are your thoughts on graphene in Turnigy batteries. Supposed to be new chemistry but I’m not sure. I can say from experience they tend to stay stable longer than the Nano Tech

[@HolmesHobbies]

graphene is a great battery tech. I have good word that they are actually graphene doped.

[@billderas3420]

Mad scientist at work today...LOL

[@NC_RC]

Internal Resistance - what are your thoughts on this? Is it a reliable indicator of the pack health and is there a universal point at which a pack should be considered "expired"? For example, I have a couple of 2s packs: a newer 3250mAh which shows ~12ohms when charged and an older 5200mAh which shows ~35ohms when charged and both 'look' fine. Is there a correlation between pack size and optimal/dangerous resistance?

[@HolmesHobbies]

absolutely it is a good indicator. but you need to know where the pack started to know the health today. while higher resistance cells aren't more dangerous, they do sag more and heat up more. the older pack has higher resistance because it is older, and maybe it also had older tech when it was made.

[@NC_RC]

@@HolmesHobbies Ah, ok, thanks. So if the Pack's history is unknown (came with a used crawler) then is it just a case of keeping an eye on the resistance over time and monitoring for sudden resistance increases?

[@JustinDDavis]

@@NC_RC temperature effects IR as well..so if they are colder your IR will be higher. Lipos like to be room temperature or warmer for best performance.

[@Br0rB]

GensAce 3s 4300mAh in my Scx10 II, 3s 1200mAh in my main WPL, 2s lipo or liion in my small crawlers (WPLs, eazyrc, Hobby Plus, Orlandoos). 3s is so, so much better if the truck can run it.

[@CornholioMcGeeRC]

Awesome info!! Hey John I just got a new maxamps 5c 5000 mAh Graphene battery and they are claiming 175c it’s got 10ga wire on it. You think that could be true or are they exaggerating a bit? There has to be a true limit to how high the C rated can go I imagine. Just wondering what you think. Thanks!!

You will not believe this. I use Tamiya connectors on my Tamiya kits and my crawlers too. I have used Tamiya connectors on both 2S and even 3S LIPO batteries. I have had no problems with them. I do understand that Tamiya connectors are not very good. I have also used Tamiya connectors on high speed cars and they melted. Thoughts?

What about the Traxxas charger live Bluetooth

[@johannjoesten648]

Question for you John. I often run my batteries down to 3.85v per cell. Is that going to hurt anything?

[@rc-daily]

Thats not even getting it down to nominal voltage. Take them down to 3.3-3.4v.

[@johannjoesten648]

@@rc-daily thank you so much

[@ryurc3033]

100% 3.3 -3.4 is totally safe and actually leaves them pretty darn close to a decent storage charge

[@rc-daily]

@@ryurc3033 that's exactly why I run them to 3.3-3.4. That way I know they would be fine if I had to leave them sitting in the lipo bag for a month or 2

3s 1300 for my scx and 3s 2200 up to 4200 in my trx4 depends on crawling/hikeing

[@furball5553]

watched this video twice and its still Chinese arithmetic ✌

[@fishnrc294]

My problem is most run times on the batteries are not true & most often are far short of the advertised run time. So you get at 4500S & it’s only 3800mha true time. I guess the higher quality more expensive batteries are more true to the run times advertised. Problem is there are so many brands on Amazon unfortunately a lot are just cheap versions. I’ve had good luck with lipos so far but definitely can tell some don’t last as long or go bad. A good charger wil tell you if it’s bad or not chargeable & why. I definitely have respect for these batteries because even now they can be kind of sketchy.

[@HolmesHobbies]

4500mah is a rating at 1c discharge. cell quality determines how close to full runtime it will deliver at 5c, 10c ,25c etc... There are plenty out there that deliver 90% or better rating at 25c.
