Amptron 48V 75Ah / 75A cont discharge LiFePO4 Battery

AMPTRON® 48V 75Ah Lithium LiFePO4 Batteries are an alternative replacement (AR) for most applications currently using a deep cycle Gel, AGM or Flooded Lead Acid battery. The maximum continuous discharge current is 75A and peak discharge current 200A for 5 seconds.

Our batteries come with a 4 year warranty and are designed using only the highest quality components. This includes the use of a robust Battery Protection System (BPS), aluminum encased prismatic cells, solid busbar connectors and a solid frame to reduce movement and damaging vibrations.  AMPTRON® batteries can also be placed on its sides without the risk of components coming loose or loss of usable capacity.

​Our Lithium batteries use a high quality robust integrated Battery Protection System (BPS) and is designed to manage and control all the battery protection requirements. The BPS maximises the performance of the battery by automatically balancing the cells and protecting them from being over charged or over discharged. Our integrated BPS design is what allows our batteries to be used as an AR "Alternative Replacement" for most applications requiring durable, high quality, dependable and lightweight Lithium Batteries.​
