The Amptron 12V 50Ah LiFePO₄ Battery is a high-performance, deep-cycle lithium battery designed to replace traditional AGM, Gel, or Flooded Lead Acid batteries. With a continuous discharge rate of 70A and a peak discharge of 140A for 5 seconds, it is ideal for applications such as RVs, marine systems, solar setups, mobility scooters, and industrial equipment.

Constructed with high-quality components, including a robust Battery Management System (BMS), aluminum-encased prismatic cells, solid busbar connectors, and a solid frame to reduce movement and damaging vibrations. The integrated BMS maximizes performance by automatically balancing the cells and protecting them from overcharging, over-discharging, over-temperature, and excessive charge or discharge currents.

  • High energy density, more usable energy in less space.
  • Lightweight and compact design.
  • Can safely use 100% of rated capacity.
  • Built to service higher loads without loss of capacity.
  • Flat discharge curve for longer run time and more efficient use of capacity.
  • Heavy-duty built-in Battery Protection System (BPS) with multiple safety features.
  • Explosion-proof nickel-plated steel prismatic case.
  • Flame-retardant electrolyte.
