I have a situation with my batteries that I hope someone can help me with. My setup.
Slide in Camper
4x100 watt solar panels
Victron SmartSolar Charge Controller - 100/30
2xDLB-G24-12V Lithium batteries
For simplicity, I'll refer to the batteries as 204 and 956 - the last three numbers of their serial numbers
Battery wiring.....
Jumper cable on positives and jumper cable on negative terminals
Connected in a charge/load configuration
shore power connection (charge) -positive on 204 and negative to 956
Inverter Connection (load) - positive to 956 and negative to 204
The situation is this, when 204 reaches 100% SOC the charging stops - both batteries go to an idle state and charge controller goes to a "float" charge.
Currently, 204 is at 100% and 956 is at 62% SOC. I have checked the connections and all are tight. I'm using multi-strand 2/0 cable from batteries to inverter and shore wiring is the same.
I'm suspicious that the charge controller "sees" the two batteries as one and when one shows 100%, then the controller considers them charged.
Why does 956 not continue to charge to 100%? I have the charge controller set to lithium batteries which according to the manual is a preset configuration. Is there a setting in the charge controller that I can change?
Thank you for your help
