Charging issues.
I have a diy electric sailboat and my main battery bank is a diy 48v 280ah and works and charges fine. My backup bank is 4 -100ah litime that makes a 48v bank.
I checked the backup bank today and the voltage is 51.2v and it won't accept a charge. My victron mppt jumps at absorption and with a multimeter I see there is no amperage going to the batteries. Same thing with a lifepo4 charger (generator)
The individual litime reads
12.9
12.8
13.1
13.1
The two batteries are separated by a switch (batt1 and batt2 option) I can still use the backup bank for discharge so I assume it is not a connection issue
What could cause this and what should I do ?
Thank you!
