Lipo repair

[gimpygolden]

Hey Linc, how goes it?
Just wondering how the batteries are going? I know you got the A123's done just wondering about the 5s Zippy's you were knocking down to 4s for me. Also don't forget to add in the 20Xl motor.
thanks man

Whoops, guess i forgot to reply to your last PM... Sorry about that, you hoser

I have wired the a123 packs, just need to shrink them. Will pull the zippies apart tomorrow afternoon and get them ready, much easier and quicker to do lipo stuff... Should have all of those done then, will post pics of the finished results and get them in the mail by the weekend for you. And I have the 20xl set aside too.

Do you want deans females on the a123 packs? Did not specify in your instructions...

No prob, will do that and get everything in the mail tomorrow afternoon. I will post some pics before I package. The blue shrink you sent will be a bit big on the zippy packs, can I use some black that I have?

I will pm you when I am done.

Linc, or anyone....

Has anyone taken apart the TrueRC Hardcase LiPo Pack yet?

I think one of my cells MAY have puffed... As it was a bit lumpy, on the top, barely, like, 1mm over in the center, and I'm OCD, so I'm scared as shit.

I think it was Mr. Spongebob Avatar, something pede?
Who had one, and got his balancer plug stuck in, so I'm assuming he opened it?

Sorry, can't remember your name!

Anyways, someone... help?

No idea, never had my hands on one of those packs.

[rawfuls]

Awww, damn.

How are most of the hardcased you handled configured?

I tried taking one apart..... Smelled like lead, so I put it back together..

[lincpimp]

Not sure I understand. Some are 1p, some are 2p. Usually the case is lightly glued around the edges.

NEW TrueRC 5000mAh 20C 7.4V 2S2P pack

Off TrueRC's site...

Wait, doesn't that mean it's 4 cells?
wtf, I'm retarded.

[lincpimp]

Yep, uses 4 2500 cells. Ahh, a 2p pack having issues...

[rawfuls]

Hmm, never thought of that...

I'll email him, I opened it like a couple cm's, and it wouldn't budge anymore, so I didn't do it.
TrueRC won't tell me how to open it... Maybe if I tell them it might be puffed and my life might be endangered..

Anyways, are they just loose packs, with bullet connectors on the tips, or is it glued in?

Ehee Linc, still working on my lipos :D:D. U can keep 'em.. Not worth much money I suppose?

[rawfuls]

Linc, after I felt the top of my hardcase a little lumpy, I tossed them in my icepack, it's like a long medical ice pack, that I keep in a shopping bag.

I wrapped it around the lipo for about an hour or two.

It was quite cold when I pulled it out (I left it on my table in room temp), it wasn't a lump much.

How do puffed lipos act, if you charge em up, they shouldn't hold right? How fast do they drop? What should I be looking out for?

Right now, I'm charging them at 1A, and they're 2 Cell, 5000mAh packs.
So 4A less 1C..

Is this a good idea?

[lincpimp]

Charge them all the way up, write down the voltages and let them sit for 24hrs. If the voltage drops evenly between the cells you are good to run them. Go easy for the first run and see if it puffs. If not try a little harder. After a few runs you will be able to tell if they are ok or not. Check the voltage of the cells after the run when they cool down. If they are way out of balance you most likely have a bad cell or 2...

[rawfuls]

Damn...
Okay, will do.

Thanks Linc...
