Description

AMPTRON® 12V 50Ah Lithium LiFePO4 Batteries are a Plug and Play replacement for any application currently using a deep cycle Gel, AGM or Flooded Lead Acid battery. The maximum continuous discharge current is 50A and peak discharge current 100A for 5 seconds.

Our Lithium batteries have an integrated Battery Protection System (BPS) and are designed to handle superior abuse tolerance. The BPS maximizes 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 any application requiring high quality, dependable and lightweight Lithium Batteries.
