36v DYNO4 Dynamic Charger
Description
The Monster Marine Lithium DYNO4 Dynamic Charge System is a true 4-bank smart marine charger engineered from the ground up for anglers who demand total energy control on the water. Custom-built and field-tested by professional anglers nationwide, it keeps every battery in your boat fully charged, perfectly balanced, and performing at peak efficiency - automatically. Whether you're plugged into shore power at the dock or running your outboard mid-trip, the DYNO4 adapts in real time to your system's needs.
Say goodbye to center battery imbalance in your 36V trolling setup. The DYNO4 delivers a dedicated charge lead to each battery, supports emergency jump-starting directly from your trolling bank, and can even wake lithium batteries that have hit low-voltage cutoff - all without manual input. It's the all-in-one charging, monitoring, and safety solution built for serious anglers who can't afford surprises on the water.
Key Features
- True 4-Bank Dynamic Charging: Individually charges and balances 1 cranking battery and 3 trolling batteries (12V each, 36V system) with a dedicated charge lead per bank.
- MML Smart Battery Monitoring: Integrated Monster Marine Lithium Smart Battery Monitoring automatically supervises voltage, health, and balance for all batteries while connected to shore power.
- On-The-Run Charging: Monitors and prioritizes your cranking battery while the outboard runs, then redirects surplus current to trolling batteries - keeping your full system topped off while you fish.
- Built-In Emergency Jump-Start: One button activates reverse-charge mode, pulling power from the 36V trolling bank and converting it to 14V / 30A to jump or recharge your cranking battery on the water.
- Automatic Lithium Battery Wake-Up: Auto-detects low-voltage cutoff on lithium batteries and safely wakes the BMS to restore charge flow with zero manual input required.
- Universal Battery Compatibility: Works with Lithium-Ion, LiFePO4, AGM, and Flooded Lead-Acid batteries - one charger for your entire system regardless of chemistry.
- Wide AC Input Range: Accepts 100-240V AC, 50/60 Hz for reliable operation anywhere you have shore power access.
- Max Output - 40A Total: Delivers 14.4-14.6V at 10A per bank for efficient, balanced charging across all four banks simultaneously.
- Short Circuit and Reverse Polarity Protection: Built-in safeguards protect both the charger and your batteries from common wiring mistakes and electrical faults.
- Rugged Marine Build: Salt-resistant, vibration-tested, and sealed to withstand the harsh demands of on-water use season after season.

FAQ
Can the DYNO4 charge both lithium and lead-acid batteries in the same system?
Yes - the DYNO4 is compatible with Lithium-Ion, LiFePO4, AGM, and Flooded Lead-Acid batteries. It intelligently manages each bank independently, so even a mixed battery system can be charged and maintained effectively within a single setup.
What does "On-The-Run Charging" mean?
On-the-Run Charging means the DYNO4 actively manages your batteries while your outboard motor is running. It prioritizes keeping your cranking battery fully charged first, then automatically redirects any surplus current to your trolling batteries - so your entire system stays topped off even while you're out on the water fishing.
How does the Emergency Jump-Start feature work?
If your cranking battery dies on the water, simply press the onboard button to activate reverse-charge mode. The DYNO4 pulls power from your 36V trolling battery bank and converts it to 14V / 30A of output to jump-start or recharge your cranking battery - getting you back up and running without needing a separate jump pack or assistance.
What happens if my lithium batteries hit a low-voltage cutoff?
The DYNO4 features an Automatic Lithium Battery Wake-Up function. If a lithium battery's BMS shuts down due to low voltage, the DYNO4 automatically detects this condition and safely sends a controlled wake signal to revive the BMS and restore normal charge flow - no manual intervention required.
Does the DYNO4 require professional installation?
The DYNO4 comes with pre-terminated DC output leads with ring connectors and a full user manual covering setup, safety, and troubleshooting. Many anglers install it themselves, though if you're not comfortable working with marine electrical systems, having a qualified marine technician handle installation is always a good idea to ensure safe and optimal performance.
Is the DYNO4 suitable for use in saltwater environments?
Absolutely. The DYNO4 features a rugged marine build that is salt-resistant, vibration-tested, and sealed for harsh on-water conditions. It is designed specifically for the demands of marine environments, whether you're fishing freshwater lakes or saltwater coastal waters.
