Learn MoreParallel Connections: Wiring batteries in parallel increases the current or ampere hours. ... Improperly connecting batteries can lead to the cancellation of energy and rapid discharge. In contrast, batteries connected in series properly add their output voltages, resulting in a greater overall voltage. ...
Learn MoreTheir voltage(SOC) is the same. Battery "A" has 1 Ah and battery "B" has 2 Ah. We parallel these together. Discharging: Most people seem to agree that battery A would simply take 1/3 of the discharge current and battery B would take 2/3 as the voltage drop on B is slower than A. Charging: I would argue that the opposite will occur when charging.
