battery charging

Miniscule differences in SoC (voltage) can cause excessive current to flow from one battery to the other until they balance out. You may want to temporarily put a load between the batteries to limit that current. After a while, the batteries will have the same voltage and will charge and discharge in parallel just fine. $endgroup$ –
