If you depend on auxiliary batteries to power your adventures, work, or equipment, keeping them charged and healthy is critical. But managing separate chargers, monitors, and regulators can be complicated. That’s where a battery management system (BMS) comes in.
A battery management system is an all-in-one solution that controls every part of your auxiliary battery setup. Instead of piecing together multiple devices, a BMS combines charging, monitoring, and protection into one smart, compact unit.
WHAT DOES A BATTERY MANAGEMENT SYSTEM DO?
A BMS does much more than just charge your battery. It manages power intelligently by:
- Charging your battery from multiple sources including your vehicle’s alternator, solar, and mains AC shore power
- Automatically prioritizing the best available power source with Green Power Priority™
- Monitoring battery health and showing real-time state of charge, power use, and time remaining
- Optimizing charging for AGM, Gel, Calcium, and Lithium batteries
- Protecting against overcharging, deep discharging, and electrical damage
With a BMS, you know exactly how much power you have, where it’s coming from, and how long it will last.
WHY DO YOU NEED A BATTERY MANAGEMENT SYSTEM?
- Simplify your setup - A BMS combines chargers, monitors, and regulators into one system, making power management easier.
- Protect your investment - Batteries are expensive. A BMS extends their life by charging them properly and preventing over-discharge.
- Know your power - Real-time monitoring shows your energy use, charge levels, and how much runtime you have left.
- Stay off-grid longer - By managing multiple power sources efficiently, a BMS helps you maximize energy use and remain independent for longer.
WHERE ARE BATTERY MANAGEMENT SYSTEMS USED?
A BMS is essential anywhere reliable auxiliary power is needed:
- Camping & Overlanding: Run fridges, lights, and accessories without draining your starter battery.
- RVs & Vans: Keep appliances running and devices charged at camp.
- Boats: Power electronics, pumps, and lights on the water.
- Worksites: Operate tools and equipment where mains power isn’t available.
