BMS Technology

The internal battery management system in the Seastar Marine series is the only one of its kind on the market. Not only protects the battery from over-discharging and short-circuiting but allows the battery to be compatible with almost any modern battery charging system or alternator as a drop-in replacement for existing lead-acid/AGM batteries. This BMS also allows the battery to safely discharge and charge at a constant rate of up to 200A, and to discharge in short bursts at an astonishing 300A. Meaning these batteries can handle massive load draws, and recharge quicker than any other battery of their kind.

Ultra Light Weight

Lithium batteries give the added advantage of being ultra lightweight. Seastar Lithium batteries will weigh as little as a third of the weight of an equivalent lead-acid battery.

Ultra Long Life

Seastar lithium batteries show unmatched cycle life at 100% depth of discharge testing. Designed to last 10 years or more when cared for and used correctly, the long life of these batteries will actually lower the cost of use over time when compared to using traditional lead acid batteries that need to be replaced regularly every 3-4 years. The deeper discharge abilities and quicker charging times that our lithium technology provides also result in less generator run time for the end user, meaning less hassle and more savings.

100% Waterproof Sealed Casing

Perfect for marine applications, the battery casing that houses the cells and internal BMS is fully sealed and IP66 rated.
