The NBT Lux Charger 12V/20A 4-Bank is an onboard charger designed for multi-battery 12V systems common in bass boats, center consoles, and larger offshore vessels. IP67 waterproof rating means it can be mounted in wet compartments or bilge areas without concern. Each of the four isolated banks delivers 20 amps to its own 12V battery, and the charger includes a LiFePO4-specific charge profile that prevents the overcharging and undercharging that shortens lithium battery life.

CHARGER RATING
Input: 100-240V AC
Output: 12V DC per bank, 20A per bank (four independent banks)
Total system capacity: 80A across all banks when charging four batteries simultaneously
TERMINAL CONNECTIONS
Four sets of independent output terminals, one per bank. Each bank has positive and negative ring terminal connections. Status indicators per bank show charging progress and fault conditions.
WATERPROOF RATING
IP67 rated. This means the charger is protected against dust ingress and can withstand temporary immersion in water up to one meter deep. You can mount this unit in bilge compartments, under casting decks, or other locations where standing water or direct spray is a concern.
COMPATIBILITY
Designed for 12V LiFePO4 (Lithium Iron Phosphate) battery systems. Works with 48V configurations (four 12V batteries in series), 36V setups with an additional cranking battery, or any multi-battery house bank arrangement using 12V lithium cells. The charger includes spark-proof technology, reverse polarity protection, and automatic thermal regulation. Do not use chargers designed for lead-acid or AGM batteries on lithium systems. The charge profiles are different, and using the wrong charger will damage the battery or leave it undercharged.
