A new system using 2 x 12v lithium batteries to make a 24 volt supply. Victron Blue smart charge control with 1 Kw of PV. The batteries are nominal 12v , but have a maximum voltage of 12.6v. Operating voltage of 10 - 12.4 v.
When charging, the difference between the batteries is up to 0.6v which is too high. I have set the target voltages in the charge controller 24.4 absorbtion and 24.2 float.
The battery balancers are set to remain off until the voltage is above 26.6. It would be useful to be able to use a balancer in this system, but i see no way to adjust this setting which is too high.
Other solutions ?
