Default EP4200 Dead Shorting.

Hi All,

I have heard mixed comments about dead shorting EP4200, is this a good idea ?

I also have an EP4200 pack that is new, done about 1 run with it in the car, and as i was taking it out of the car, it touched a tool on my bench and it shorted 2 cells, it touched across 2 cells, shorting them out like as if you soldered 2 cells together in a loop. the 1 cell had a bit of liquid come out, is this pack now toast?

Thanks Ya`All

Bad idea. You will kill all the runtime in the pack and risk creating dead cells. The EP4200 should be kept above .7-.9V at all times.

The liquid was the cell venting. That is not a good thing but the cell is not necessarily toast. It may not perform like it did when new but may still work. It all depends on how much damage was done during the shorting.
