Quick technical Q&A

Will it overcharge my battery if I leave it connected?

No—once the battery reaches full charge, it switches to a maintenance/float stage to hold storage voltage instead of continuously charging.

What battery chemistry is it meant for?

This unit is intended for lead-acid + LiFePO4 (selectable). Always confirm your battery type and voltage before connecting.

How do I choose the right amperage?

Lower amps are ideal for maintenance and small batteries; higher amps are better for faster recovery on larger batteries. If unsure, pick the lowest output that comfortably meets your use case.
