Is this charger made for lithium batteries only?

It is specifically tuned for LiFePO4 lithium profiles, which is its main design focus. Check your battery chemistry before buying if you run flooded or AGM lead-acid.

Can it charge two batteries at once?

Yes. It has two independent banks, each delivering 20A, so two 12V batteries charge or maintain simultaneously.

Can it be mounted in a wet bilge?

Yes. It is fully encapsulated and IP67 rated, built for wet, high-vibration spots like a bilge or storage locker.

Does it work with NBT LUX batteries?

It was engineered to complement the NBT LUX lithium series, so pairing it with those batteries is the intended setup.

Do I need a separate charger for a third battery?

Yes. This is a fixed two-bank unit, so a third battery needs its own charger or a larger multi-bank model.

Our take on the Nbt Lux Charger 12v 2 Bank 20A AC-DC Onboard Charger

The NBT Lux Charger is a two-bank onboard marine charger built for dual 12V battery setups. Each bank delivers 20A, and the profiles are tuned for LiFePO4 lithium batteries, so a pair of LUX-series packs can reach a full charge safely. It is fully encapsulated and rated IP67, which suits a wet, vibrating bilge or locker. Against general-purpose onboard chargers, it trades broad chemistry support for lithium-focused charging and rugged sealing.
