Frequently Asked Questions

Can I charge four batteries at the same time?

Yes. The charger has four independent 12V banks, and each bank provides up to 10A of output. That means each connected battery gets its own charging channel instead of waiting its turn on a single-port charger.

Is this charger only for lithium batteries?

It is optimized for LiFePO4 charging, but the supplied specification also notes auto-detect battery type. If you plan to use it across different battery chemistries, confirm the exact supported battery profiles on the live product page before installation.

Can it stay mounted in the boat year-round?

That is the intended use case. The charger is designed for permanent onboard installation and carries an IP67 waterproof rating, which makes it better suited to marine compartments than a portable garage charger.

How long will it take to charge a battery bank?

Charge time depends on the size of each battery and how deeply it was discharged. Since each bank provides 10A, smaller batteries will recover faster, while larger deep cycle batteries will take longer and should be sized with that charge rate in mind.
