The NBT Lux Charger 12V/36V 2-Bank is an onboard AC-DC charger that handles two different voltage systems at once: a 12V output for your cranking or electronics battery, and a 36V output for your trolling motor system. It carries an IP67 waterproof rating for reliable installation in the bilge or other wet areas. The charger uses a charge profile optimized for LiFePO4 batteries, which matters because lithium chemistry requires precise voltage control to avoid shortening battery life or triggering BMS shutdowns.
SPECIFICATIONS
WARRANTY
See manufacturer warranty
CHARGER RATING
Input: 100-240V AC
Output Bank 1: 12V DC, 20A
Output Bank 2: 36V DC, 20A
Each bank delivers 20A independently for fast recovery on high-capacity lithium batteries.
TERMINAL CONNECTIONS
Two isolated banks with dedicated output terminals. Each bank connects to its respective battery system. Reverse polarity protection built in.
WATERPROOF RATING
IP67 rating. The enclosure is fully sealed against water immersion up to 1 meter, which covers bilge installation and exposure to washdowns or rain intrusion.
SMART BMS COMMUNICATION
Wake-up feature included for lithium batteries that have entered low-voltage protection mode and locked out the BMS. The charger sends a signal to reactivate the battery for charging.
COMPATIBILITY
Designed for LiFePO4 (Lithium Iron Phosphate) batteries in 12V and 36V systems. The charge algorithm is tuned specifically for lithium chemistry. Do not use an SLA or AGM charger on lithium batteries. The voltage profiles are different, and using the wrong charger will either fail to fully charge the battery or trigger BMS protection, depending on the mismatch.
Experience the NBT Marine Advantage
The NBT Lux 12V/36V 2-Bank eliminates the need for separate chargers when you are running mixed voltage systems, and the IP67 rating means it installs where other chargers cannot.
