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.

Can I use this on a 12V system?

No—this model is for 6V batteries only. Using it on 12V can damage the charger and battery.
