48v 30a lifepo4 reports 54v at battery but 26v in bms
I purchased this life po4 battery about 2 years ago
I have pictures attached
The sad thing is I managed to screw it up the first week I got it by shorting the battery but it could have been more.
I think I touched the two polarities together but may have done something else but I'm not sure cuz I don't remember.
When I test the voltage with my multimeter on the battery before the BMS it shows a full 54 or 55 volts as it should.
However when I test it when it's connected to the BMS it only shows about 25 volts.
I also noticed when I try to charge it up that some red lights turn on the BMS.
Batt 16 to batt 11 red lights
Does anyone have any idea what I should do to perhaps try to reset the BMS or something similar?
Should I simply replace the BMS or can I do something more simpler and cheaper?
