I have a 3s Zippy soft case that has about 20 cycles on it. The other day it quit working like it had an open circuit some place. I test at the plug with my DVM and it shows 11.6V but will fluctuate to 8.8 when the board is pressed or moved around. None of the cells looked damaged and none are swelled.
When i plug in to the esc it does nothing. When plugged into 2 different chargers one shows over voltage and the other shows open.. Actually i did 3 chargers, mine showed bad balancer connection.
My questions if whether it is safe to pull all the solder off the tabs and wires and re-do that work. I am more than comfortable soldering but i was told by the LHS to recycle it. They were concerned with an open spots in any of the cells causing a fire while working on it.
If i do resolder it all, can the board touch the alum casing on the lipos?
