LiFePO4 Lithium Batteries for Mobile and Off-Grid Power

Lithium iron phosphate (LiFePO4 or LFP) batteries deliver high usable capacity, stable voltage under load and a long cycle life in a lighter, more compact package than lead-acid. This range covers 12V, 24V and 48V lithium batteries from Victron Energy, Enerdrive, Exotronic, Invicta and Pylontech. Capacities run from compact 20Ah units up to 400Ah house batteries for caravans, RVs, boats, 4WDs and off-grid installations.

Choosing the Right Lithium Battery

Start with system voltage, daily energy use and the space available. Then match the battery design to how you plan to charge, monitor and protect it. Key differences across this collection include:

• Built-in vs external BMS: Victron SuperPack and SuperPack NG batteries include internal protection for simple drop-in upgrades. Victron Smart and Smart NG LiFePO4 batteries are designed to integrate with an external BMS for larger, system-controlled installs.
• Bluetooth monitoring: Exotronic Alpha and Apex models and Victron Smart batteries allow state-of-charge and cell data to be checked from a phone.
• CANBus integration: The Exotronic Axion 300Ah comes in Caravan and Marine versions for communicating with compatible chargers and displays.
• Form factor: Slimline options from Exotronic and Enerdrive B-TEC suit tight under-seat or under-bed spaces. IP67 models such as the Enerdrive B-TEC Ultra and Exotronic Alpha IP67 offer added water and dust resistance.
• Cranking capability: Invicta Hybrid lithium batteries carry 800 to 1400CCA ratings in standard case sizes such as LN2, LN3, 95D and H31H.
• 48V storage: The Pylontech US5000-B 4.8kWh rack-mounted module, Victron 48V Smart NG and Exotronic 48V Alpha batteries suit larger inverter-based systems.

Charging and Protecting Lithium Batteries

LiFePO4 batteries perform best with lithium-compatible charging profiles from your mains charger, solar regulator and DC-DC charger. Pair your battery with suitable shunts, low voltage disconnects and isolators from our battery management range. These help you monitor state of charge accurately and protect the bank from over-discharge.

Common Use Cases

Caravans and RVs: A 200Ah to 300Ah 12V lithium battery supports fridges, lighting and inverter loads for extended free camping. High-capacity options are available in our 201Ah+ batteries collection.

Marine and boats: IP67-rated and marine CANBus versions suit house banks where moisture resistance and weight savings matter.

4WD and canopy setups: Slimline and compact 50Ah to 100Ah batteries fit drawer systems and canopies. Invicta Hybrid models can serve as lithium starting batteries.

Off-grid, tiny home and commercial: 24V and 48V batteries reduce current draw and cable size for larger inverter and solar systems.
