The NBT Lux Charger 12V/12V/36V 3-Bank is a multi-voltage onboard charger built for boats running both 12V house systems and a 36V trolling motor. It's IP67 waterproof, fully sealed for bilge mounting, and delivers 20A per bank with a LiFePO4 charge profile that brings lithium batteries to 100% without overcharging or triggering BMS cutoffs.
SPECIFICATIONS
WARRANTY

CHARGER RATING
Input: 100-240V AC
Output: Two 12V banks at 20A each, one 36V bank at 20A (60A total)
Charge Profile: LiFePO4 / Lithium Optimized
TERMINAL CONNECTIONS
Three independent banks with ring terminal outputs. Reverse polarity, short-circuit, thermal overload, and over-voltage protection on all banks.
WATERPROOF RATING
IP67 rated. Fully sealed against water, salt, and dust. Shock-resistant casing for bilge mounting in high-speed applications.
SMART BMS COMMUNICATION
Integrated lithium wake-up feature activates batteries that have entered low-voltage protection mode, restoring charging capability without manual intervention.
COMPATIBILITY
Designed for NBT LUX Lithium LiFePO4 batteries across 12V and 36V systems. The LiFePO4 charge curve is not interchangeable with SLA or AGM profiles. Using a lead-acid charger on lithium batteries will result in incomplete charging or BMS shutdown. Using a lithium charger on lead-acid batteries will overcharge and damage the battery.
Experience the NBT Marine Advantage
The NBT Lux 12V/12V/36V solves the hybrid system problem without mounting three separate chargers. One waterproof unit charges your cranking battery, your electronics battery, and your trolling motor system at the same time.
