2-Time Best Lithium Battery
Bought 2 x 100Ah which we use to run our fridges. So impressed with their endurance that I've just bought another 2 for the caravan! 
Power for What Matters Most
With 100% usable capacity and steady voltage, this battery runs your essentials for longer. Based on 1,200Wh of real, usable power from a full charge, with this battery, you can run:
-
60L camping fridge Up to 4.5 days in mild weather, 2–3 days in hotter conditions
-
32" LED TV 27+ hours of total viewing time
-
Laptop ~16 full charges
-
Small coffee maker (via inverter) 100+ cups brewed
-
2V water pump Weeks of normal shower/sink use
Works With Your Setup
The VoltX 12V 100Ah LiFePO₄ is compatible with most solar charge controllers, DC-DC chargers, and mains AC chargers with a lithium profile. Perfect for caravans, 4WDs, boats, home backup, or off-grid systems. Supports series and parallel connections (up to 6 batteries).
*For high-power or high-capacity needs, we recommend our 200Ah and 300Ah models for optimal performance and battery health.
Built to Last for A Decade
Enjoy up to 4000 charge cycles — that’s up to 10 years of regular use. Unlike lead-acid batteries that lose capacity after a few hundred cycles, VoltX maintains reliable performance for years, saving you money and replacement hassle.
Safe, Strong, and Built for Every Adventure
From camping trips to 4WD missions and off-grid living, this battery is designed to go where you go. Powered by premium lithium iron phosphate (LiFePO₄) Grade-A prismatic cells, it delivers reliable stability and efficiency.
The integrated Battery Management System protects against overcharge, over-discharge, overheating, and short circuits — so you can focus on the journey. With its rugged aluminium cell-casing, wide operating temperature range, and international safety certification (IEC 62619), it’s proven to perform in extreme weather and rough terrain.
Easy to Carry with One Hand
Weighing as little as 10.8 kg, it’s up to 70% lighter than equivalent AGM batteries, making installation and transport simple for anyone.
Fast Charging, Less Waiting
Supports charging currents up to 100A (model dependent) for rapid fast charging with our VoltX SRNE 50A AC LiFePO4 Battery Charger - fully within 2 hours.
Whether you’re topping up from solar, vehicle, or mains power, you can go from 20% to full in just a few hours with the right charger.
Smarter Value. Better Power.
VoltX delivers premium-grade safety, a longer lifespan, and more usable power than budget lithiums — all at a fair price. It’s the smart choice for anyone who wants dependable performance without paying premium-brand prices.
