i'm wondering what the absolute lowest voltage is on a lipo where it might still be an option to recharge it. The snowmachine with the battery pack in it is up in greenland, and the mechanic said that the bms isn't working....he sent me pics and for some reason one of the bms slave modules isn't doing its job. either the voltage on the cell is too low (somewhere around 2 volts or less) for the module to work properly, or the module is damaged somehow. i told him to check the voltage with a multimeter and see what the cell voltage is actually at.
depending on the voltage...what do you think is a possibility to recharge from? i've read that if they get too low there is a really good chance they will catch on fire when charging.....
the charger for the pack operates at at a C/9 rate. (5 amps, into a 45 aH pack)
if the cell is at 2 volts is it worth trying to charge it? i realize there's always the possibility that it can catch fire...but i've never done the tests myself to know what the chances are. there are also temp snap switches inside the battery box that activate at 150F, which will open the main contactors and stop charging if they are tripped.
Thanks ES!
