Mixing Battery Sizes: What Happens?

You cannot connect batteries of different amp-hours in series with good results.


We strongly recommend you DO NOT attempt to mix battery sizes (amp-hours) and connect together. Due to differences in battery management systems and battery cell counts, there may be a charging and voltage discrepancy between batteries.


This will cause the highest voltage battery to charge the lowest voltage battery attempting to create balance in the circuit. The greater the difference in voltage, the higher the probability of battery failure.
