Li-Po Fire - Another classic case of not balance charging

Lipo fire-lost charger and burnt heli! - HeliFreak

On that thread someone was parallel charging using a PL8 when a cell failed. The PL8 stopped the charge. Someone else tried to recover a cell by cycling and caused a fire. There seems general agreement that not balance charging is a cause of some fires.

I don't think a PL8/6 will even let you do an unbalanced charge on anything over a 2S lipo pack for safety reasons.

I have a 6s 5000 with a bad cell ( 1.4v) !! I tried to bring the cell up in my pl8 and it goes briefly into 'safety charge' but rejects the pack as bad.
Was very interested in Hayden's post about charging the bad cell on a nicad charge to slowly rebuild it ??

Your PL8 is doing its job

You can still make up a charge lead to target the one cell via the balance wires but I'd suggest you do that outside and a long way from anything you value ...

I assume the total pack voltage also suggests the cell is faulty and it isn't just a balance wire making poor contact?

I think you'd get a different error from the PL8 if that was the case, but just making sure.

I recieved a duff battery from hobbyking where one cell was virtually flat, my pl8 brought it back up to where it should be but that cell still failed in flight. I guess there is no real way to revive a cell once its gone that far.
