Will 2 Batteries in Parallel Equalize? (Here is the Answer)
Number one First of all, when connecting batteries in parallel, it''s important that they are both the same voltage. If one battery is 12V and the other is 24V, they will not work together correctly. Number two Second, it''s also important that they are both the same type ...
Charging batteries in parallel is different than charging them in series. Series and parallel battery systems have different uses so charging them in their own unique ways is needed to account for the differences between them. Use the appropriate charger and setup for series and parallel circuits.
Bringing Batteries on a Plane: TSA''s Rules for Staying Charged Up
