Frequently-Asked Questions
Can I leave the charger connected when boat is in use?
Yes, it’s designed for continuous DC output and automatically transitions between charging stages.
Is it safe to mount near water?
Absolutely. With a full IP67 waterproof rating, it can be installed in engine bays, under floors, or near wet areas.
Will it work on a lead-acid battery?
No—this charger is specifically tuned for LiFePO₄ and should not be used with lead-acid systems.
Does it require ventilation?
No active ventilation is needed. Sealed aluminum casing dissipates heat effectively during operation.
