Did this video help you?

Kanari Mentos: hi thanks for the video i do have question i do have quad copter with battery 350mah with wall power when i ido have other battery from store it puff or burn why but the same but different company and what does battery hase protect thanks

derjoh1986: good stuff man!! right watching this, I've repaired battery!!!

Alex Pozgaj: I have two brand new zippys, never been in the air, which both seem to have the same problem - I'll try to repair them now, thanks for the great and informative video, I really learnt something new!

halleffect1: $60, wow. that's a $10 battery now. lucky for us RC guys the prices went way down.

Jason B: Brian, I love your videos and fly RC as well. I made the switch from Deans to Anderson PowerPole connectors. I learned about these from Ham Radio and knew they would work in RC as well. They are easy to connect and are also easy to connect and disconnect when your in the field. Keep up the great videos!

Anthony Gillian: i have one of those 11.1 volt lipo batteries, i crashed my quadcopter on the roof of my apartment and it sat there overnight turned on....looking at the prop's it looks like they were spinning the whole time it sat there, i plugged the battery to the charger after i got it back and it just doesnt want to charge, is there any way to fix the battery anyway??

mumforddale1: people dont do this its very dangerous!!!unless you really know what your doing like he do.lipos are cheap hobbyking has them for cheap and ebay you can find something nice.just looking out do you want but this is to risky!!!

silverss onyoutube: i have no idea what your talking about on how to repair it , so im gonna open mine up and start soldering everything to blow myself up hahaha

rcAllDayLong: did you ever get it figured out? if not, try this: does your main discharge leads show 7.6v or 11.4? if 7.6v, then 3rd cell is dead, if 11.4 then 3rd cell is fine and you just have a break in the balance lead on the 3rd cell- most likely the last red wire.

Goregoon: @briansmobile1 LoL ☺☻☺☻☺☻☺☻☺☻☺☻☺☻☺☻☺

briansmobile1: @450hp202turbo Blow it up!.... for entertainment purposed ONLY! X D Just make sure to get it on video so you get add money. JUST KIDDING! But seriously.... I would ; )

briansmobile1: lol I'm kind of into everything!

motokid032: I am having this same exact problem right now..Voltage meter only reads two cells unless I wiggle the wires, it then shows all cells online. Thing is, I opened her up, and all connections are solid..Any Idea what that could be? I thought it may have been the metal prongs inside of the balance lead but it seems to be the negative balance wire heading to the cell. I'm stumped. No cuts or tears that I can see. Help Brian!

Tazman000007: Thanks m8, worked a treat , only bought the battery 2 days ago not even used it .. Shorted it out and fixed it just as u showed, good job.thx

covercalls88: To help avoid problem while soldering a new plug especially on a T-Plug. I would strip one wire put a shrink tube on the wire, solder the wire, and cover with the shrink tube before soldering the next wire. From experience when soldering a new connector, never have more than one wire exposed at a time. I did manage to short a battery years ago when I had two wires exposed. Lesson learned for me.

anything896: I have the same battery and to let the air escape I poked it with a needle. I think I hit the reversed cell. Now my battery will run but only a few min. I hope I can fix it anyone have an idea!

Ollander Parker: Thanks man. Just fixed mine. Was just about to toss it too. I just tape off the other terminals so that the solder wouldn't spread too far.

tyler seymour: I just did that exact thing. Now i know how to fix it thanks.

Chris Olinger: @XxNx007xNxX you can get amazing 3s 40c 5500 or 5000mah at nitrocrx.com for 28 to 38 bucks their skylipos

cw88shade: is that a skylane plane on your ceiling??

briansmobile1: @PROJ3KTJ30 Great question. The discharge rate that is made possible by a better plug causes heat in the battery. It's the HEAT that causes the puffing. If you got new plugs put on and then pilot like a granny you'll find that your batteries don't puff up.

skimowhite586: @briansmobile1 It was kind of a give away with your cars hood open.

briansmobile1: Learning moments happen. When this was done I was still on my first real RC heli. (blade 400)

ApplePro: What LiPo is this is this a Gens Ace

briansmobile1: @joshuaejackson I'll have to make a vid. That's something I've had a lot of interest in, in the past. I'll make a vid.

covercalls88: The balance lead could be bad. There are actually two places you can test for voltage on the lead. One is where you will normally plug it in and another where it locks the pin in. I would not worry too much about the voltage at the balancing plug except when charging using the plug. What is critical is the voltage at the main plug.

Jeremy Lopez: just curious, can this battery pack "start" a car?

Hio Ontario: so all you done is show us that a missing cell is likely to be solderring gone bad across the terminals? my god you do go on talking bs.

dojmike: So the solder joints act like a fuse. Interesting. Thanks.

thedefog: Thanks for the info, just got a new 3s lipo tonight that I stupidly shorted, and this is identical to what I just repaired. Just charged it up no issues, replaced it with an identically sized solder dot to act as a fuse again in case of shorting.

briansmobile1: @rodriguez2131 It's just called a lip tester. It's generic. I got it from HobbyKing.

Soldier53flyer: Great Job! I wish I found you before I recycled two batteries. nice to know. thank you.

covercalls88: If you are not getting any voltage from the third cell it might be dead or the foil where the wire soldered is to is broken. I've taken apart about 100 lipo batteries over the years and have salvaged many for my RC airplanes. I've even removed dead cells from a 6 cell pack and made it into a 5 cell. You have to be careful when cutting or soldering the pack, Be sure when working with a lipo you have access to a door to the outside so you can toss the battery out if you make a mistake.

Joshua Jackson: good work! nice solder

roman: Hi great video. Can you tell me how you recycled your other battery?

Peter Nguyen: Well I avoid the problem all together by not cutting off both wires at the same time. I cut the negative, then solder on the new plug. Only after it was done and heat shrunk would i solder the second one.

Adrian Lowe: Perfect and sensible precautionary intro. Did it with care. Thanks.

briansmobile1: That's what I said... lol

briansmobile1: @Tazman000007 You're welcome

briansmobile1: @skimowhite586 Yes.

briansmobile1: If you hurt yourself.... you should sue yourself.

briansmobile1: @Tymopta You're welcome friend.

briansmobile1: @cw88shade It is.

briansmobile1: @ollanderparker You're welcome- good job / good thinking.

briansmobile1: Nope. You did it. I just threw info on the interwebs.

VxO4fame: Hmm wouldnt this mean you are not be able to charge it properly again?

ILLEST_COREY: i noticed that all the batteries that i have bought puff when i change the connectors. hobbytown did my connectors on a 2-cell it puffed. my dad did the connectors on a 3-cell it puffed. and my other 3 cell is fine because it already had traxxas connectors. is it the connector or the battery?

tombj388: i did it and it kill me so i;m dead now.

briansmobile1: @rcjoseb Thanks

Kotuku Reedy: Im gunna give this a go right now the same thing happened to me but the spring kind of metal on the end of my deans charge connecter bent when i was plugging it in and shorted out the lipo
