Quantium™ Lithium Iron Phosphate (LiFePO4) Battery 12.8V 42Ah

Quantium™ Deep Cycle Lithium Iron Phosphate (LiFeP04) batteries are a safe, high-quality, energy-efficient, lightweight drop-in replacement for traditional Lead Acid, AGM, GEL batteries. They are featuring an integrated quality smart battery management system (BMS) to ensuring the safe operation and protection of the battery by monitoring and managing the charging and discharging process.

These LiFePo4 batteries are designed to replace lead-acid batteries for Caravans, Motorhomes, Campers, 4×4, Water Craft, Trolling motors and are perfect for storing solar energy.

Many of the cheap lithiums flooding the market today that use low-quality cells, which results in not only poor performance but worst of all poor safety. Quantium™ batteries are made with the best materials by reputable manufacture; this shows in the quality of their construction and high continuous power output. 


Quantium™ LiFePo4 12.8V 42Ah Deep Cycle Lithium Iron Phosphate batteries come with a genuine two-year replacement warranty by Maxon Batteries, an Australian family-owned business, this also backed locally by Battery Central Brisbane.
