CANBus Batteries

CANBus Lithium Batteries for Integrated Power Systems

CANBus batteries go beyond storing energy. They communicate battery data, such as state of charge, voltage, temperature and charge limits, to compatible inverter-chargers, battery management systems and monitoring devices. Charging equipment can then respond to what the battery actually needs instead of working from fixed voltage settings alone. The result is a better-coordinated system for caravans, RVs, boats, 4WD builds, off-grid homes and commercial energy storage.

This range includes LiFePO4 and lithium batteries from Victron, Enerdrive and Pylontech, plus the Axion CANBus Bluetooth series. Options run from compact 12V 100Ah units to 12V 300Ah high-capacity batteries and a 48V rack-mounted module for larger installations.

Featured CANBus Battery Ranges

• Victron Smart NG (NextGen) LiFePO4: 12V 100Ah and 150Ah options designed to integrate with the Victron ecosystem. Learn how they pair with Victron's BMS in our guide Introducing Victron NG Lithium Batteries and Solar BMS.
• Enerdrive B-TEC Ultra: IP67 waterproof lithium batteries in 12V 100Ah, 200Ah and 300Ah sizes. They suit installs exposed to moisture, dust or confined, hard-to-reach spaces.
• Axion 12V 300Ah CANBus Bluetooth: Available in dedicated Caravan and Marine versions, with Bluetooth for convenient battery status checks.
• Pylontech US5000-B: A 48V 100Ah (4.8kWh) rack-mounted module for off-grid homes, tiny homes and commercial or industrial energy storage. Modules can be expanded as demand grows.

Why Choose a Communicating Battery?

A battery that reports its condition gives the rest of the system accurate information to work with. With compatible equipment, CANBus communication can help optimise charge rates, coordinate protection events and give you clearer visibility of system health. This matters most in larger lithium systems running inverters, DC-DC chargers and solar together, where several charge sources share one battery bank.

How to Choose the Right CANBus Battery

Start with system voltage. Most caravans, RVs, boats and 4WD setups run on 12V, while larger off-grid and commercial installations often use 48V for lower current and smaller cabling. Next, size the capacity to your daily energy use and the number of days you want to run without recharging.

Check communication compatibility with your existing inverter-charger, GX device or BMS before purchasing. A battery from the same ecosystem as your other equipment usually makes integration simpler. Consider the installation environment too. IP67-rated batteries suit damp or exposed locations, and marine-specific versions are built with boating applications in mind.
