Monster Marine 36V Lithium Battery Charger

The Monster Marine Lithium Dynamic Charge System 36V is a dual-purpose bench and onboard charger designed for boats running both 12V cranking and 36V trolling motor systems. It charges both banks simultaneously from shore power, diverts alternator current to your trolling batteries while underway, and includes reverse-charge capability to jump your cranking battery from the 36V bank in an emergency. The integrated Smart Battery Monitoring system tracks and balances all connected lithium batteries while plugged into AC power, maintaining optimal charge and waking dormant BMS units automatically.

CHARGER RATING
AC Input: 100-120V AC
DC Output (Shore Power): 14.4-14.6V @ 10A (12V bank) and 43.8V @ 10A (36V bank)
On-the-Run Charging: 43.8V @ 10A to trolling system
Reverse Charge (Emergency): 14.6V @ 30A to cranking battery

TERMINAL CONNECTIONS
Pre-terminated ring connectors on DC output leads. Charge status LEDs on top of unit indicate active charging.

SMART BMS COMMUNICATION
Integrated MML Smart Battery Monitoring system continuously tracks battery health and maintains optimal charge balance while connected to AC power. Automatically wakes lithium batteries from low-voltage BMS cutoff and resumes charging without manual intervention.

COMPATIBILITY
LiFePO4 and AGM batteries. Designed for 12V cranking systems and 36V (3×12V series) trolling motor systems. On-the-run charging prioritizes the cranking battery first, then diverts excess alternator current to the 36V bank once the starting battery reaches full charge. Emergency reverse-charge function converts 36V bank power to 14.6V @ 30A for cranking battery boost, available as timed 30-minute assist or emergency mode.
