Hey Andy I love your channel, I take your opinion on drones serious when I consider a new purchase. With that being said do you have any experience with the tyro119? I'm in the market for a 5-6 in drone and saw your nazgoul 5 review and that is an option. But the tyro119 has gps and is way cheaper. Thanks for any input.

[@demandieselengineeringmanu5355]

Validation; this was the reason I brought my FD200 but I was in no way as scientific, as ever great vid Andy

[@Sandwich4321]

Am I able to use this method to chatge lipos for flights, I have a mobula 6 on the way and only one charger

[@rc-fannl7364]

Nicely made DIY series harness. Btw, around 8:24, even though it's only a short time, charging 300mAh batteries at 2.8A seems like pushing it. That's almost 10C charge rate, while most manufacturers afaik advise not to go over 5C, which in this case would be 1.5A charge current. And even that might be pushing it for these small batteries, which are always the highest quality.

[@JEMTAC]

cheers Andy, all my old 1s lipos were puffed up. Recently got eight beta fpv 1s and four happy model 1s, they are all the same as when I got them, excellent. Did not make my own adapter but many thanks.

[@pateachongthu]

Can i connect only 2 or 3 lipo in this 6s setup?

[@soccernerd200]

No, needs to be 6

[@engizmo]

Thanks Andy. Made a similar thing myself. Also used ph2.0 shorted plugs to change the cable to be anything from 6s to 2s. I wish some one would make a dedicated 1s charger that does this tho.

[@maxwellduff4958]

I was wondering this very thing, just short all the unused ports? I've been trying to figure out if this would work but haven't tried it yet.

[@engizmo]

@@maxwellduff4958 yep it works.

[@daveday5507]

Very ingenius. I'm not sure that I would trust it, but you may have revolutionised charging. One picture shows 7 cells.

[@AndyRCchannel]

which picture? cheers

[@daveday5507]

@@AndyRCchannel The thumbnail appears to show 7 dells, but I aee now that one isn't connected. Maybe I should learn to count. Having thought about it, does the charger stop charging the high cell and continue charging the low cell? Or does it cut off when the overall voltage reaches 6 x 3.8? In this case, one cell could be higher and one lower.

[@sheapyfpv8224]

Would you recommend this type of cable rather than a balance board?

[@TheBuzzorca]

Just made myself a 4 and a 2 of those lipo charging leads copied from yours,Thanks Andy.

[@bertbeinaaf8314]

I made this type of connector/discharger about a year ago. Works great 👍 Good idea to first charge them and then use storage charge. I’m gonna try that one...

[@kelapse8587]

I thought you can't mix different mah in series charging method or you can only if you discharge or storage them?

[@sheapyfpv8224]

So if you have multiple batteries to charge and they are outside the 1amp difference how do you get them to roughly the same voltage so you can parralel charge them?

[@fipen2852]

If i charge at 1C mixing different capacity batteries,i assume i just use lowest capacity battery's C rating to charge them?

[@Billbobaker]

I just ordered a 6s and 4 s from banggood for $6.. great review Andy.

[@paco_rider]

Hi guys can i charge a bunch of 1s lipos (same capacity) in parallel without a balance connector? Making the charger thinks that there is only one larger lipo connected?

[@rogueFactor]

when you run out of x gauge heatshrink in the middle of soldering... dammit.

[@robertdefiance2314]

Hi Andy, we're thinking quite the same. I use the Fractal Engineering board with a jumper to vary between 1S - 6S and run all the cells through the iSDT FD-100. Takes about 10min to bring down to 3.8V. One question though.. if I was to use a 1S Parallel board, what is the safest maximum voltage differences between each battery? For example: for charging 6S(s) in parallel, each LiPo pack must not be more than 0.6V apart, for 4S, it's 0.4V apart max, 2S = 0.2V. Would 1S(s) mean each battery must be 0.1V? That would be quite impossible no? Thanks!

[@Cre8ionz.]

5:17 min - there is NO down side, if you have PH2.0 ( battery side ) jumpers.. Just use 1-2 zip ties to never loose them.. ( jumper secure next to the plug )

[@nicstroud]

If you are storage charging your batteries, what's the hurry?

[@overdosed51]

I received one of these in a fpv package. Can i fully charge them off the hobby grade charger at like 1 amp

[@onden]

Great video! I have a noob question, if I get 1 to 6S is it possible to use only 3 or 4 of the 1S connectors? My limited knowledge of electrical engineering tells me know but I would like to make sure.

[@TheAmericanALEx]

Great videos! So just to be sure: I could also charge my 1S LiPos with this 6S cable using my 6S charger? You're only talking about storage charging here. Also I could charge down to 2 batteries as well using jumpers in between, right? Seems like a better idea than to buy a designated 6-way 1S charger if I already have a 6S charger.

[@ELValenin]

You can do that, but make sure they always have the same voltage when you plug them in. That's the disadvantage of a setup like this.

[@TheAmericanALEx]

@@ELValenin I've used it quite a bit and I never checked the voltage. The cable is in series so it really shouldn't matter, right? The charger sees it as a 6S and just balances it like that. If one of the 1S batteries is already full it just charges the empty ones. Worked great so far. I think you confused this with a parallel board. I actually ended up merging this and muteFPV's ( kzbin.info/www/bejne/g2Wce42Dh92CZ5o ) versions. It still is a cable but with the positive as a separate cable.

[@ELValenin]

@@TheAmericanALEx ah yes I mixed that up, sorry. Thanks for the mod tip!

[@pxsaber2177]

Such a great solution. Any idea if this works with an IMAX B6, which does not support HV batteries?

[@AndyRCchannel]

it will work but it will store them to the same voltage which is fine. you just cant charge them to a hi volt. Hi volts and non hivolts can be stored at the same voltage as there isnt any different between the two apart from the hivolts are being over stressed.

[@surfriderMK]

So if I want to charge 2x 1s Lipo using your adapter method on my balance charger does that mean I would have to charge it as a 2S?

[@djs134]

So using this setup if I was to charge 6 1s lipos to 4.1 before I storage charge like u did, my question is since we have the balance lead plugged in , the lipos can be at different voltages right? Like 3.3, 3.4, 3.6? And the balance feature will get them all to that 4.1 when u stopped the charging to then storage charge for the last step.

[@sixtofive]

I've been wanting to solder up a harness like this for a while for just this purpose. Nice project!

[@Rich-TeaFPV]

I storage charge my 1s lipos on my skyrc b6 charger with a parallel board but it does take a lot longer. 😁👍👍

[@Miguaelable]

I need some help I can't discharge my 1s batteries ith my hota d6

[@Kilodelta_]

If I get the 6 PH.2 to 1 XT60/30 and only need to charge 4/6 batteries, can I use two fully charged 1s lipos to sit as place holders whilst I charge the other 4 as the balance lead will tell the charger they don't need charging or will this damage/impair charging in some way?

[@davidlondon3111]

I don't understand something here Andy. The batteries are around 300 to 450 mah so how can you discharge/charge to storage at say 4 or 5 amp? Are you saying that as long as it's just going to storage level it's ok to charge/discharge at say 10c? I do have a series harness like this but just set the max current to 1c and use my regular charger

[@AndyRCchannel]

as I say you can discharge or charge at a lower rate, but when people tell me they just fly the packs down you will be pulling at least 2 amps in a hover and up to 10 amps if you give it some throttle. Either way iv been doing this for a while now and its better than leaving them discharged or fully charged but you can do 1c if you like. The problem is when you have charged 30 batteries or more, even at 1c its gonna take some time. if you watch the fast discharge or charge it only ever reaches 2.5 amps because its discharged them quicker than it could ramp up to 5 amps.

[@mani-00]

Thanks for the video! so im trying to follow your steps i got the XT60 to 6 1s cable and im using the Imax BAC V2 charger but when i try it it just take a minute and say successful but nothing is actually done! my batteries are 1s LIHV 450mah and when selecting the power im puting 0.4a as it is for a 450mah ...what am i doing wrong?

If I ordered this and had a few ph2.0 jumper plugs couldn’t I insert 1 to make it 5s and 2 to make it 4s and so on?

[@ScAnZ_7]

Say you have two 1s batteries 300 mHa 3.7 v each battery = set charger to 2s this doubles the voltage but keep the amps to a single battery 0.3 amps. Using cables with two connectors for two batteries and a balance lead. If you want to charge three batteries make/buy a cable for three batteries and a balance lead and set the charger to 3s and amps to 0.3 amps.

[@djs134]

G J I understand that but wouldn’t the 6s cable work fine for 4 lipos if I used to jumpers for 2 of the ph2.0s? Then charged on 4s

[@djs134]

Instead of buying multiple configurations I mean

[@ScAnZ_7]

@@djs134 maybe i am not understanding but... use 1 lead per battery. so for 2 batteries 2 leads and a balnce lead for two batteries. 3 batteries 3 leads and a 3 balance charge lead and so on. Match the balance lead to the amount of batteries you are charging.

[@birdy356]

in minute 5.23 you say it won't work with fewer accumulators. just make some "dummy" plugs where the two poles are connected. and use them instead of akku ;-) that way they are connected again to the next one and you have enough with a 6S cable.

id say look at some of the turnigy batteries the same capacity as the stock one

[@th0rfpv]

Why is is ok to charge with 5A/2,5A? Thought the harness basically creates a 6s 300mAh lipo which you are basically charging with 16/8c. Doesn't this hurt the battery?

[@attackthedefault8042]

I made a series harnesses for 3s parallel boards so I could storage charge two dissimilar packs at the same time and caught a lot of flack for it but I'm still looking at doing it this way cause I run 3s 520 mAh on my toothpick builds then the same packs but in series for my 3" Tarsier builds increases the 6s pack options exponentially when I can use toothpick batteries and I haven't run into issues from using two xt30s

[@AndyRCchannel]

i understand. doing out of the norm thing with volatile lipos can always raise eyebrows. I was worried about this video for a while but iv tested it a hundred times and no issues

[@spongesteve]

I've built the 6s harness (seen it somewhere else and like you didn't have a good bulk storage charging solution). However I've only been using it with the same capacity and indeed brand of LiPos for fear of setting fire to something! Its interesting that you are using a mix of capacities and advice on this isn't something I've been able to find. I guess the only issue is that you are potentially charging at greater than 1C if you set the charge current for the highest capacity battery and have some with lower mAh - right? And I guess we are talking (in my case with 260 and 300mAh batteries) about a 0.04A difference in charge rate. Rounding error really?

[@GeorgeCooper_LoneWolf]

I have 20x 1S LiPOs... I just simply end my flight early and the LiPO stabilizes to 3.8 ready for storage. They are all 650mAhs so yes I am getting enough fly times to make this bearable.

@@AndyRCchannel Yeah I understand you, I used to get bad sag from the PH2.0 connector as well so the XT30 helped a ton... I can fly my long range tinyhawk freestyle build (400mw + R9mm) from 8.7v to 8v for around 2m.. My longest fly time is 10min dropping the voltage to 6.4v but I get around 6-7 if I land early to let the battery end in storage voltage.

[@verofpv6152]

Fantastic video, Andy! Thanks a lot! 😃 I made a few of those series connectors, but I still have to replace the JST for XT60s. I haven't any at the time. 😬 BTW, take a look at the little board Mute FPV made. You can use it with 1 to 6 cells at the same time!

No they need to have similar voltages

[@amay8282]

Awesome video Andy and a real time saver. I read the fine print on some new GMB 650 mAh packs I bought and they say their research shows a storage level of 3.3v per cell has shown to maintain the cells the best, thoughts?

[@mqrichfpv2748]

Curious in how the batteries handle 'little over 1C charging' over time as well as your opinion on exchanging PH2.0 to SYP instead of BT2.0. I see, you're making it out on 'top' and 'bottom' voltage, but in my mind, the current of 10C while charging still exists. I'm more conservative and say, don't overstress while charging. You mind giving us an update on this in a few weeks? Keep it up! Cheers.

[@AndyRCchannel]

In flight depending on the model you can be pulling anywhere between 5 and ten amps per battery. So for me what I'm doing here is not the issue. Check out my meteor 65 video on my thoughts on the bt2 connectors for very small batteries. Cheers
