My Victron charge controller seems to think my battery voltage is higher than it actually is according to my BMS 712. This seems to cause the charger to go into float mode too early and not fully charge my battery. Only seems to charge to a little over 80%. You can see from the screenshot below that my charge controller thinks my battery voltage is 14.2 but it is actually only 13.47. FYI: I am running 200 amp hours of battle born lithium batteries. Any way to remedy this?
If I turn off the charge controller and then restart it I get a much higher wattage initially, but then it drops quickly down into float mode even though my battery is only at about 80%:......
Here it is less than a minute after restarting the charge controller, you can see how much the wattage drops for no apparent reason....
And here are the BMV numbers....
