Lipo repair

[nitrostarter]

Linc, I have (2) Rhino 5s 4900's, and (2) Rhino 3s 4900's. Interested in reconfiguring these to (4) 4s packs?

I'll be running the 2200 on 4s in both 8T and 8B and 4s seems to be prime in both.

hey linc, you think you could resolder this?
the tab broke off in my neuenergy pack. only a small portion of tab remains.

Couldn't you just peel away the wrapping around the tab, and solder a new tab onto it, Linc?

Dunno, might explode in your face, but could that work... Theoretically?

I have fixed similar issues with broken tabs, so I guess I could do it again.

No prob. I will get to them tomorrow for the repairs, the a/c in the hobby room crapped out so I have to fix that first. It was 110f up there today, no fun sweating and trying to fix lipos!

What are the specs on the tp packs, in case I have to charge them, and for my general knowledge. They look like 25c packs, but what mah are they?

Yeah, I arc a few packs here and there, can't be afraid of a few sparks now and then!

What mah are the tp packs? Sorry to keep asking, but the labels have velcro over them. And I do not want to overcharge them.

Hmm, sounds like you have a bad cell on that rhino pack. Can you set your lvc to 3.2v per cell and give the pack a full run till the lvc kicks in? If the charger only puts back 1700mah that is all you have used, not even half of the pack...

[Slash Racer]

I did not mention that but it has always been set to 3.3 volts per cell. I ran it to cutoff the run before it only charged this much.

[Slash Racer]

When I charged it it does not even start charging at 4.9 amps like my other batteries do. It starts at about 4.2

[lincpimp]

You must have a bad cell. It is dropping voltage badly, and letting the pack voltage get low enough so that the lvc kicks. I can pull the bad cell out, or at least test the pack, but it may be cheaper/easier to just buy another pack, those packs are about 40 bucks new...

I have a neu energy pack that should be here tomorrow but I was just seeing what could be wrong. I figured it might have had a bad cell. I have only had it since january and have only charged it about five times a week sometimes not using it some weeks.

Linc,
your pretty good with soldering..(duh:)) and i was wondering if you knew how they made these...and if it could be done with the existing male/female plugs i have.....
