You can put it on a slow and low NiMH mode charge for a while to get it back into the safe range. Do this outside away from any flammables. If you can get it back above 3.2v per cell, then switch back to a balance charge and see what happens. ??Can I save the battery? it´s a lipo with balance cable.
Thanks i´ll try that =)You can put it on a slow and low NiMH mode charge for a while to get it back into the safe range. Do this outside away from any flammables. If you can get it back above 3.2v per cell, then switch back to a balance charge and see what happens. ??

Yeah i always do... But not this one time.. It was a gap between that bash and by the time i got home i planned to do it next morning.. But never did. Aand it was a while ago.Nice one, try to avoid that happening as other than overheating.. nothing damages your battery like getting it below V min.
Charging them to storage voltage after a days sesh is a great habit to get into and reduces the chances of this happening.
Charge it up and let it sit overnight, then check the voltage's on each cell in the morning.
The last pack I had that dropped a cell voltage wouldn't retain it for more than a few hours after charging. Even then, when trying to run it, it would dump 5 minutes in, so it was useless anyway.
Just something to check at home before you get out to bash and find your pack is flat just as you start your run.
Mine even dropped quite a bit after a few hours and was below 2V by morning on that one cell.
Have a multimeter but how do i check individual cells? ?There should be a battery meter function on your charger. If not, get a battery checker. From like 1-2$ up. Or get a multimeter and learn how to use it!
But yes, if nothing else, you can initiate a charge and check the cell voltages immediately after it starts.
Thats great... Thank youIf your charger doesn't have a cell meter program you should try a balanced charge and try scrolling across to the individual cell screen.
If you are unable to do that you can test individual cell voltages from the lipos balance plug with a meter as follows..

(6s)
black -> yellow = cell 1 (3.7V)
yellow -> orange = cell 2 (3.7V)
orange -> purple = cell 3 (3.7V)
and so on..
black -> orange = cells 1 + 2 (7.4V)
yellow -> purple = cells 2 + 3 (7.4V)
black -> purple = cells 1 + 2 + 3 (11.1V)
and so on..
