Designed for 36V Trolling Motor Systems
The MillerTech 1210-3615 is ideal for fishing boats using a dedicated 36V lithium trolling motor battery alongside a separate 12V lithium battery.
Common applications include:
-
Compatible 36V lithium trolling motor batteries
-
12V lithium dual-purpose cranking batteries
-
Dedicated 12V marine electronics batteries
-
Bass boats and other fishing boats with separate 12V and 36V lithium battery systems
Both charging banks operate at their respective voltages, allowing the two battery systems to recharge without requiring separate onboard chargers.
Charging Multiple Batteries in Parallel
The charger can also be used with compatible lithium batteries connected in an approved parallel configuration.
For example, two compatible 36V lithium batteries connected in parallel can form a larger-capacity 36V battery bank.
Always follow the battery manufacturer's parallel-connection and charging requirements before connecting multiple batteries.
Installation & Compatibility
The MillerTech 1210-3615 is designed for compatible 12V and 36V LiFePO4 lithium battery systems.
-
Connect the 12V charging leads to the 12V battery or approved battery bank.
-
Connect the 36V charging leads to the 36V battery or approved battery bank.
-
Connect the charger to a suitable AC power source when charging.
Verify that each battery supports the charger's specified charging voltage and current.
Important: This is a dual-voltage lithium battery charger. It is not designed to charge a standalone 24V battery, and the two outputs must not be connected interchangeably.
Why Choose MillerTech?
The MillerTech 12V/36V Dual Bank Marine Charger provides a straightforward way to charge both your trolling motor and cranking/electronics lithium batteries from one onboard charger. With dedicated charging outputs and a 3-year manufacturer warranty, it's a practical solution for modern marine lithium battery installations.
