Description
These batteries are designed using only the highest quality components and are backed with our 4-year warranty. This includes the use of a robust Battery Management System (BMS), Aluminium encased prismatic cells, solid busbar connectors and internal protection to reduce movement and damaging vibrations. Our batteries can also be placed on their sides providing versatile installation options.
The integrated Battery Management System is designed to monitor, protect, and optimise each cell within the battery. The BMS maximises the performance of the battery by automatically balancing the cells and protecting them from over charging, over discharging, over temperature, and excessive charge or discharge currents. Our integrated BMS allows our batteries to be used as an alternative replacement for most applications requiring deep cycle batteries, however if the charging system does not support a Lithium charge profile, there are some compromises – please contact Amptron for more information.
