Replacing LiPo Main/Balance Leads

[@d.b.cooper]

Wow it’s been almost 2 years since his passing and I still find his videos relevant and helpful! Thank you J.D.

[@sapata1871]

Still learning from this Man . RIP.

[@discofever3048]

very sad

[@chad9160]

What happened to him?

[@Andreas-vr3vs]

what???

[@JonnyDKUK]

RIP, still learning from you man... you are missed.

[@mikescantlin5912]

This channel has taugh me so much about wiring and how our lipos work. RIP dude.

[@techFPV5964]

JD was truly a genious in his own right with ANYTHING that had to do with Drones,Tx'rs geez you name it and he was a pro in which ever area you needed help in..Only the greatest die young!!I am truly grateful for all of his videos he left us.

[@creativeflash1713]

You're true man , i grew up watching his tutorials and guidance . He surely be happy up in heaven after watching all the love fpv community give himm .❤

[@techFPV5964]

Every time i watch one or 2 of his videos(i have the whole catalog) i SMH on where he would be in the our fpv world today. A Josh Bardwell times 1000.And i say a prayer for his family each time. JD was one of a kind period and a genius. ❤️✈️✈️🙏🙏

[@ThePurpleSnork]

Thank you for your help, once again. I know you’re not with us anymore, but your videos are better than anyone else’s. RIP

[@kyongkim702]

Anyone else here in 2021 and still learning from this man? I had no idea he passed years ago, let alone in a motorcycle accident which really struck a chord with me since I'm an avid rider. Ride in Paradise!

[@MrDLRu]

Just stopped by...Other than using the wrong tip, should be the 1/8 wide one, a good vid. I disassembled a 6S to 4S because 2 cells went bad, and I can't get the solder to stick to the battery pad/lead...don't know what's going on. Even tried some acid flux and that isn't working??

[@marcsangiuliano4273]

That was so helpful!!! And I think your video is the only one of its kind on KZbin! You explained everything so perfectly and why you did other things. It couldn’t have been any better! Thank you

[@dr00minFPV]

Thanks dude, it worked for me. I am so glad I saved this awesome 1500mah LiHV 6S. The only difference, the balance lead solder point was so hard to melt, my soldering iron kept dropping temperature and I ended up solder-repairing the cable itself.

[@EmDoubleA]

Love your videos! Consider using a chisel tip on connections with that much solder. The larger tip acts as a heatsink to prevent fluctuations in temp from the heating element to the solder work. edit: also consider popping out and switching the balance leads to get brown to be ground in order to know 100% which side is ground in the future

[@JL-sn1ee]

always hits hard when you google something and a project blue falcon vid is the first thing that shows up. RIP

Excellent video JD. Still teaching is. RIP...and thank you for your instructional videos. Always top notch.

[@TurboTyler]

You make some of the best videos man, appreciated.

[@vuchuong74]

Agreed. I always worry about apply hot air to shrink the shrinkwrap. Does this ever damage the lipo? Would you do this to a puffed lipo? I presume that you wouldn't try it at all if there is some puffiness... would really like your opinion though.

[@ivymike83]

This is a very excellent educational vid on the construction of these batteries... they're expensive enough that I wouldn't consider cutting the heat shrink off the packs at all, but this broke things down very well!

[@Kradle]

Great vid man ty! I just replaced all the bearings on my Emax Rs2205 motors using your method from your old channel and it went well, too!

[@ProjectBlueFalcon]

Awesome! I'll have to make another bearing video. Glad it worked well for you.

[@Kradle]

Definitely do make another for all the guys still curious. Only thing I did different was use a table vise to gently hold the motor in place while I tapped the bearings out with a punch.

[@asgharamiri1583]

فارسی می توانم استفاده نمایم .که نتوانسته متصل شوم استفاده بهینه از کلیه برنامه‌ای خودتان نتوانسته ببرم . متشکرم

[@gregorydahl]

You can stretch shrink tubing bigger before shrinkiing it . Needle nose pliers stuck into small tubing and then spread the handles . That will fit over an sma antenna connection.

[@chrisnocker3437]

More great content, thanks. Just one suggestion, when you said "blow hot air" down the heat shrink to get the condensation so that I will slide, maybe you want to clarify for others that you are breathing hot air from your mouth as opposed to using a hot air gun or something. Just thought it could potentially catch someone out 😉

[@3000gtwelder]

Yeah, I was wondering where the condensation came from, that makes sense now lol.

[@ndscrub]

i been rebuilding lipo's for 5 years this very amazing video instead of markers on top of the shrink i right down the info on paper can cover it with cleartape on the cell before i do shrink on the battery wow dident think anyone else would think use hot glue under main leads great mind think the same thats awsome aswome

[@rodheal]

You can 'wet' any contacts that don't soften quickly with a flux pen. Great video to save batteries which have lead damage only.

[@TRACKACARDIA]

Still love your videos the best Bro. RIP God save us all :(

OMG just found out he passed away how sad. RIP bro you'll be so missed

[@15andye]

when i make 18650 packs i use my cheap 40 watt weller with this almost solder tip for soldering stained glass just the small tips dont hold heat to well

[@ASerenidadeEstoica]

10k's man, I repair 2x 3S with problems... very nice tip's and images

[@IceCreams62]

It is better to swap brown and red wire to have red on positive balance lead !!!

[@WillyFPV]

Going to try it! Bad bal.lead venom drive hard case 25c 5000mah. 49.95 new. Thanks a bunch. I knew there'd be a way..

[@godsun358]

Still teaching us thank you God bless

[@MyDave3000]

I am so gutted you are no longer with us rip Jc

[@crissan5035]

that red or brown is the ground? so why is it connected to the positive lead? that red and brown is the hot the blacks are the ground or the fallowing positive on the next battery. That red is the positive lead wire and the fallowing wires are all in black cause they are connected in series and also act as ground in the batteries connection sequence.

[@MrDLRu]

Most balance lead wires are colored wrong, as there is only one negative lead, and all the rest are positive.

[@johndonohoe9165]

If you are making a new battery , what can you use for wrapping around the pack

[@MrDLRu]

I've used a good 3M clear package tape. Use the thin cardboard like what cereal boxes are made of, to pad the ends.

[@MHMEDMINE]

RIP my friend

[@skyweaver3199]

This is an invaluable video. Thank you.

[@meanjellybeanproductions]

Big thanks 🙏🏻

[@lw216316]

I have a 3s lipo 2700mah battery - when I put it on the charger it appears to get a full and balanced charge. when I test it on a battery checker using the balance plug - nothing shows up - completely blank if I test it using a esc / motor tester using the ec3 plug all appears well. I've tried several different battery checkers that all work on other batteries - so that's not the problem. It seems to be a fault with the balance plug somehow - why it works when charging and not with a battery checker I don't know. I think the battery would be safe to fly with on my rc plane since the balance lead is not in use when flying but I don't have full confidence in the battery since I can't check the charge with a regular battery checker. What can the problem be ?

[@MrDLRu]

It's most likely the balance plug isn't touching all the leads to the battery checker. Most definitely if the battery charger is showing all the cells and their individual voltages.

[@jobbo89]

my wires got chewed up in the spur gear and ripped in half. How do I know which wire connects to which port on the balance plug? And do I need to use solder or can I just wrap the wires round each other, since there's very little current running through them?

[@6teeth]

Can put a piece of paper inside wiht nfo before heatshrink.i

[@JonHosford]

Use your phone to take a picture of the lead layout before you take everything off. Now you have a reference. That goes for anything I'm doing. Especially flight controller wiring (Don't have to reinvent the wheel and figure it out from scratch that way.)

[@docmatt31765]

i have chopped up my balance leads and want to attempt this

[@yaffajaff]

Great vid. Trying to find a vid of someone cracking open a hard case battery, if that's possible?

[@EricSmith-lj7ln]

So does it matter which way the wires go back on?

[@TweakRacer]

RIP bro. I'm sure your looking down from heaven and thinking that you should have told everyone to tape off the solder joints that weren't being worked on, and to use flux for that last stubborn balance lead joint.

[@d.b.cooper]

Miss you buddy...

[@profitfpv8377]

RIP... Still learning

[@johnnyg3681]

If you want to replace your t to a xt60 why not just remove the t instead of all the wires? Why replace balance leads that are good?

[@SunriseWaterMedia]

Maybe as a demo for us

[@KaizerTest]

Cool vid. Now I know how to repair my batteries after they fly out of my car....hahahaha.

[@tonil6604]

you've burn the brown wire a lill bit. but I've got a question. I've got 2 battery types ( 2cells). both with different colours at the balance ports. does it matter witch colour the cables have? 1 battery: 2 reds 1black 2 battery: 1 red 2blacks till now I've only charge battery 1. can I charge them both without worries? thanks for your help

[@MrDLRu]

On ALL balance leads, there is ONLY ONE negative, and all the rest are positive. The negative has to be in the RIGHT location on the balance plug. It doesn't matter what any of the colors are. In reality, all the wires should be red except the one negative lead.

[@estebanfranco8955]

what is the order of the cell from positive to negative + 1234 - ? mine leads got cut in half

[@seanbryant345]

Very dangerous situation....your positive balance lead had the insulation melted down to the wire exactly where the next terminal is

[@pulsefourfpv5620]

Hi PJF. Thanks for the video. Is there any safe way to repair the cell contacts? Mine ripped right off... Thanks :)

[@Linktw0]

@David i have a drawer full of those lol, keep telling myself that they will totally be useful for something one day whaha. in any case it'll def be a let's-not-do-this-indoors operation. stay safe 😁

[@inmersouav]

Kinda related question, is there a downside in using 12AWG (too thick?) battery pigtail in my quads , I fly 4S 30A blheli_s , emax 2205S 2600kv. Thanks

[@ProjectBlueFalcon]

There's no downside. But if your battery leads are 14ga then its not needed. If they are 12ga then its fine.

[@billyoldham8894]

[@ronaldlemasters4873]

Hay man so I have a venom 2cell 30c 5000mah lipo in a hard case and I opened the case because my power wires and balance wires are damaged and I really need someone to fix them and you do a really good job. So I was wondering if you could help me out with this. I'd even pay ya and ship it to you and pay for return shipping I don't want to spend another 54.00 in another lipo. Do you think you could help me out?
