The NBT Lux Charger 12V/20A 3-Bank is a marine-grade onboard charging system for managing three separate 12V batteries simultaneously, ideal for 36V trolling motor setups or split house and starting battery arrangements. Fully sealed IP67 waterproof housing protects the unit from saltwater, moisture, and engine compartment vibrations. Built with an optimized LiFePO4 charge profile, this charger delivers the precise voltage curves lithium iron phosphate batteries need to reach full capacity without degradation, which matters because improper charging is the fastest way to shorten a lithium battery's lifespan.

IP67 rated. Fully sealed housing protects internal components against water immersion up to one meter for 30 minutes. Safe for installation in engine compartments, bilge areas, and other wet marine environments.
COMPATIBILITY
12V LiFePO4 (lithium iron phosphate), AGM, and lead acid batteries. Each bank operates independently with automatic multi-stage charging and built-in protection against short circuit, over-voltage, and thermal damage.
