The NBT Lux Charger 12V/24V 2-Bank is an onboard AC-DC charger designed for boats running mixed-voltage systems. It charges both a 12V battery bank and a 24V trolling motor system simultaneously from a single shore power connection. This unit is IP67 waterproof and delivers LiFePO4-compatible charge profiles, which matters because lithium batteries require precise voltage limits to maintain capacity and cycle life.
SPECIFICATIONS
WARRANTY

CHARGER RATING
Input: 100-240V AC
Output Bank 1: 12V DC at 20A
Output Bank 2: 24V DC at 20A
Each bank is isolated and delivers 20 amps independently.
TERMINAL CONNECTIONS
Two output banks with ring terminal connections. Bank 1 connects to your 12V house or cranking battery. Bank 2 connects to your 24V trolling motor system (two 12V batteries in series or a single 24V lithium pack).
WATERPROOF RATING
IP67 rated. The unit is fully sealed against water immersion and dust intrusion. This allows installation in exposed bilge areas or under deck where spray and moisture are present.
SMART BMS COMMUNICATION
Includes a lithium wake-up feature for batteries with BMS systems that have disconnected due to deep discharge. The charger can signal the BMS to reconnect and begin charging. Also includes over-voltage, short circuit, and thermal overload protection.
COMPATIBILITY
Optimized for LiFePO4 lithium batteries. Also compatible with AGM and lead acid. Do not use a lead acid or AGM charger on lithium batteries. The voltage profiles are different and using the wrong charger will damage the battery or reduce its service life.
Experience the NBT Marine Advantage
The NBT Lux Charger 12V/24V 2-Bank eliminates the need for separate chargers on boats running both 12V and 24V systems, reducing installation complexity and AC outlet demand at the dock.
