Hi,
I dropped a 10S5P 18650 battery pack in to water. It was just really briefly for a few seconds. After drying it thoroughly and letting it sit for a while i connected the battery to the esc again but it would not turn on. After that i connected the pack to a charger and it would charge as normally and the pack would turn on the esc again.
But here is the problem. The charger will turn green as if the battery is fully charged, but connecting the pack to a voltmeter will show just 75% capacity. After that i disassambled the pack for further evaluation and measured all series groups voltages. Four of the five groups are showing readings of 39.5V and just one group is showing the full 41.5V at which the chargers stops charging.
I am clueless at what is the case here. Do i have damaged cells in four of the five groups or is there a faulty cell in the group which reaches the 41.5 at first? Or is the BMS damaged?
Thanks for your time reading this, i am really
looking forward hearing from more knowledgeable guys then i am!
