BMS (Battery Management System) is designed to handle superior abuse tolerance. Smart Battery Lithium Batteries are dual purpose for starting or deep cycle applications and can be connected in series or in parallel. The BMS maximizes the performance of the battery by automatically balancing the cells and protecting them from being over-charged or over-discharged. Our integrated BMS design is what allows our batteries to be used as a drop-in replacement for any application requiring high quality, dependable, and lightweight Lithium Batteries.
