Hi everyone!
For a multitude of reasons, I have a couple of Victron LiFEPO4 12.8v 90Ah batteries that sat completely unused for a few years. Since the day I received them they were never connected to anything. No load or charge.
A few days ago I threw them into my system, one at a time, to charge and try to revive them. I've got a MultiPlus, CCGX, BMV-702 and VE.Bus BMS.
I noticed that my BMV-702 and CCGX's voltage fluctuates between 6V and 10.3V and different states of charge that slowly drops when it switches voltage. At no point do they read a higher voltage. My BMV-702 is set to 90Ah and 13.2V.
I charged both batteries overnight and they seem to be holding a charge. After 24 hours with no load they hover around 13.4V on the meter.
What's the deal with the CCGX and BMV-702 displaying incorrect voltage? Are the batteries shot despite what my meter's telling me?
THANK YOU!!!!
Conrad
