The best way to charge and store 1S LiPo batteries

[@fpvduck1764]

I’ve been wondering how to store them for a year now, that’s such a simple solution, i love it! Thanks for sharing! - and nice transition with the batteries disappearing one after the other 😁

[@WhirlyBloke]

Yep, it's the perfect solution. Thanks for watching.

[@PinkeySuavo]

now just buy vifly whoopstor

[@ficosk8]

Nice tip! I just need the XH balance cables, for 4S. This is a fine safe way to charge and discharge the 1S lipos! Cool!

[@WhirlyBloke]

Thanks, and I'm pleased it helped you.

[@Ja5onB0urn3]

Great idea Whirly. This is exactly what I made until I found out about a charge board from Fractal Engineering where you can select how many cells to charge (up to 6) via a jumper on the board. It's has ph2 & bt2 connections on it as well! Awesome piece of kit! He even screen prints your FPV name for you on the back of it! 😎

[@WhirlyBloke]

Nice.

[@Michael_D_show]

Thank you so much for this video. I am new to FPV and this video answers most of my questions I've had about charging the tiny whoop 1s batteries. I see reviews on YT for new chargers new features but when I look at the product it doesn't have a ph2.0 connector on it and figure i can't use it.

[@breakalegfpv9532]

thank you Bloke, always love your rational .

[@WhirlyBloke]

Thanks for watching.

[@maortega]

This was very useful, I built the cable an they all charged fine! Thanks a lot!!

[@WhirlyBloke]

Fantastic.

[@krayon70]

Hi, thanks for this great video ! Can i ask you a question ? Is it possible (i think so...) to charge (with yourDIY cable) only on or two, ..., 1S batterys(s) ? (same capacity and same voltage, of course !) Regards

[@burdfamfpv]

Thank you sir ,very clever yet simple technique just wat i needed

[@WhirlyBloke]

Glad it helped.

[@bbsheppo]

Great vid, ordered some off banggood! Wish I ordered them off you now.

[@WhirlyBloke]

They are cheaper to buy made up than to get all the component individually. Just gotta wait for delivery!

[@nyclassic4ever130]

On my last flights I just fly them down to about 3.85 volts. Much more fun and less work than all this. Then I just check voltage to be sure. Simple as that! But nice alternative here..thnx.

[@WhirlyBloke]

The great thing about series charging is you don't have to make sure the batteries are the same state of charge (voltage). Within reason the charger will balance them out.

[@maximilian5988]

When the charger has done its job will it beep or just shut down? I'm looking for one of those

[@WhirlyBloke]

Normally you can set it to stop charging or trickle charge.

[@amagnier]

Hi ! Great idea, do you have a link for an adapter to charge 2 Lipo 1S on a 2S balanced charger please ? ( 2 x JSP PH2.0 XT60 )

[@WhirlyBloke]

There's some news on this soon.

[@outboxfpv4360]

Good one sir. Can we do the same with a parellel charging board?

[@WhirlyBloke]

No. Series and parallel charging are completely different.

[@rammsteinsiegfried6750]

Nice Fortis 😊

[@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?

Great video 👌👍. Do you have a link where to buy that 1s balance charge cable in the uk?

[@WhirlyBloke]

Thanks. The UK link is in the video description.

[@erichbachman7363]

I suppose all the batteries should have the same mAH? I have a connector where I can connect 6 1s batteries and into my balance charger, but no balance cord. I have 120mAh and 150 mAh, but I suppose I should not match them? Worst case the 150mAH would just not be 100% charged?

[@WhirlyBloke]

Exactly. The batteries need to be the same chemistry and capacity. Otherwise, you'll be on all sorts of trouble.

[@gusnitaindarahyu2129]

thanks

[@hprompt166]

Hi There, one of the below comments asked can you storage charge less than (4) 1s lipo's? you said you need 4 to make it work. My question is if I want to storage charge less than 4 lipo's can I get some ph2.0 connectors and make them like a bind plug and change the storage lipo setting to match whatever amount of 1s lipo's that I have connected.

[@dakzer55]

Great tutorial on balance charging. Thanks. Is it safe to balance charge LiHV, Lipo 1s batteries using that balance cable?

[@WhirlyBloke]

You can't parallel charge with that cable. It's made fire series charging only. Parallel and series charging are very different.

[@dakzer55]

@@WhirlyBloke Sorry, I mean series balance charge a mix of 660mah 1s LiHV, and Lipo batteries using that cable.

[@WhirlyBloke]

@@dakzer55 They need to be the same chemistry and capacity for this to work.

[@dakzer55]

@@WhirlyBloke Thanks. Thats a shame will have to storage charge them one at a time 😕

[@rafal1031]

I got toolkitrc m7ac in conjunction with vifly whoop series board. I’m charging 4 lipo 220mAh, charger set at 0,2amp. It’s been 5hours now and still charging… how long should it take? Batteries are new as well as charger and vifly board.

[@WhirlyBloke]

It sounds like one or more of the LiPos is faulty. Try measuring the voltage on each one with a voltmeter. If any of them are under about 2V, they're bad. You can sometime revive them with a variable power supply and jolt them into life, but I don't recommend it unless you really know what you're doing.

[@rafal1031]

@@WhirlyBlokeI measured the voltage. When started charging it was around 3.7v each battery. When it comes to an end of charging, say 4.1v when normal charging, or 3.8v when set to storage charging, all cells are flashing red for hours on toolkitrc m7ac. On main screen, next to main voltage reading, little red letter „c” also change into red letter „v”. It only happens when charging small whoops 1s batteries such as 200mAh. Tried 2 different sets, 150mAh and 220 mah, and it seems it can not finish the process, keeps flashing red all cells for hours. However when charging a bit larger 1s, such as 500mAh, it doesn’t happen. Is it possible that m7ac is struggling to balance such small batteries?

[@billionairerich2849]

Полезное видео! 👍

[@SeanPaulPhoto]

Quick question, does this only work with exactly 4 1s batteries, or could you still charge with 1, 2 or 3 at a time?

[@WhirlyBloke]

This lead works with exactly 4 1S batteries, but you can make one that works with any number. Or use this to work with 2-6S kzbin.info/www/bejne/h6LId3h8jbSMebs

[@RAW.RacingTeam]

When charging, do you need to have 4 batteries bluffed in as if it were 4 cells. Or can you just charge 2 or 3 and leave some plugs empty?

[@WhirlyBloke]

You need all 4 plugged in with this lead.

[@k1ortia]

So say you had your four 1s cells that were 300mah each, and they were connected up with the lead as one 4s cell. Would they be charged at 300mah x four which is 1.2A or at 300mah? Cheers.

[@WhirlyBloke]

If the cells are in series, then you charge at 16.8V @ 300mAh. If they are in parallel then you charge at 4.2V @ 1200mAh.

[@quaneu9216]

for this design right it only work when i plug 4 1s lipo into it right？ means if i build for 4s it will not work with 3 or 2 or 1 lipo

[@WhirlyBloke]

That's right. But they are so cheap to make you can have several.

[@dickysoeliantoro5576]

Hi Mate. If I make one like yours. With 4s balance. All 4x1s battery musti be plugged in? Or can i just plug 1x1s?

[@WhirlyBloke]

No, you have to plug in all 4. If you want something that allows you to plug in any number, then check out my other 2 videos kzbin.info/www/bejne/b6PGoqtpgt6Yf80 and kzbin.info/www/bejne/h6LId3h8jbSMebs

[@chopwhoopz]

isnt serial charging a bad thing for 1s batteries?

[@WhirlyBloke]

No. Remember 4s lipos are just 4 x 1s cells in series.

[@davidrgilson]

I have a 6S adapter like this from Banggood, but I don't like that I'm stuck to having to plug in six at a time - I'd like to make a variable adapter, haven't figured out the circuit yet. I know it's probably simple but just brain space shortage.

[@WhirlyBloke]

I designed a switchable one ages ago. Maybe I should start making them.

@@WhirlyBloke Could I see the design? I'm certainly interested. Tiny whoops seem to be all I'm flying at the moment!

[@adamvaughan123]

I have one that has 6 ports. It's great

[@raphi01]

hi, i am thinking about getting one of these, but i have got 1s high-voltage-lipos, so 4.35 volts. For maximum flight time i would need to charge them with another charger which is made for 4.35 volts, right? (i have one but i was wondering how to put the lipos on storage voltage)

[@WhirlyBloke]

Just choose the HVLiPo @ 4s setting on your charger.

[@raphi01]

Ok, thanks!

[@creativeintelligence2100]

Can the battery be different mAh while charging? I dont have 4 of the same 1s battery so i need to use my other 1s battery which has different mAh rating in order to complete the circuit.

[@WhirlyBloke]

They need to be the same.

[@creativeintelligence2100]

@@WhirlyBloke well, it looks like i need a isdt bg-8s. I prefer to charge my 1s lipos with varying mAhs by a usb powerbank because its more portable, so i only need a battery checker to storage charge them. I have been storage charging them by periodically pulling the battery while charging/discharging then testing it with multimeter to see if it has reached 3.85V. Its a real pain.

[@antonmellinghoff1688]

Can you just connect 2 1s Batteries, set the charger to 2s charging and bridge the 2 remaining slots or does that not work out?

[@WhirlyBloke]

Not quite. The main port needs to be across the outer pins. Just follow my diagram but use 2 connectors rather than 4.

are my 4s and 3s batteries weak because I left them for like 4 months. Or would they just not work? They still run my drone and get it off the ground, but it can’t accelerate. And it dies in like 1 min.

[@WhirlyBloke]

Probably.

[@bkstepan]

Thanks for the video...nice. So this will be no different for HV charging I would assume just adjust the voltage to 4.35 and also this seems to be alot more accurate than those cheap 1s charges. Correct me if I am wrong. Thanks again for the video.

Surely a 1c charge rate for four 300mAh 1s batteries in series together is actually 1.2a, not 0.3a as you said in the video?

[@WhirlyBloke]

No, it's 300ma cos the cells are in series.

[@eatyourvegfpv]

@@WhirlyBloke Thanks for the reply, but I'm confused... Isn't a 1200mAh 4s lipo, which when charged at 1c (1.2a), just four 300mAh cells in series?

[@WhirlyBloke]

@@eatyourvegfpv Simple electrical engineering really. Batteries wired in series will have their voltages added together and have the same capacity as each battery. You add the voltages, but not the capacity. It's the opposite if the batteries are in parallel.

[@eatyourvegfpv]

@@WhirlyBloke Ah okay, I understand now. Thanks for the explanation. So in a 1200mAh 4s, each cell is 1200mAh itself? There's just four of them?

[@WhirlyBloke]

@@eatyourvegfpv Correct.

[@erichbachman7363]

I left mine for like 5 yrs, and tried to charge them now, no one works xD. Also tried to use the charger included for my copter and it started smoking, guess the fuse went! I have a high end Hyperion balance charger from when I used to have rc cars, and realized, "how the heck do I balance the 1s?" I cant even read their current.

[@krayon70]

Sorry but in balance connector (lipo) 4S there are 4 red cables and 1 black cable ; on your balance connector there are only 1 red cable and 4 black cables. On my charger ToolkitRC M6D) i have to plug the balance connector with the black (solo) cable on the left (sign "-" on the charger)... and with your connector ? Regards

[@WhirlyBloke]

It doesn't matter how many red or black cables there are. It varies on balances leads. Red should be +ve and black should be -ve at each end of the cable. The colours in between are largely irrelevant.
