Description
The Mastervolt 66012750 Lithium-Ion battery boasts easy installation, along with a long lifespan along and fast recharge, making it an ideal replacement for lead-acid batteries. This battery saves up to 70% in space and weight, recharges in less than an hour. They are suitable for use in unlimited parallel operation, or up to 10 units in series, making it easy to increase capacity in your electrical system.
The Lithium-Ion (LiFePO4) battery is extremely safe chemically, and features a waterproof electronics cabinet. It has been tested and certified according to UN38.3, ensuring it is safe to transport. It has an Battery Management System (BMS) but should be used in conjunction with an external safety relay. The MLI Ultra batteries are equipped with a self-learning balancing algorithm that predicts the behaviour of each individual battery cell and balances proactively, resulting in a faster and more efficient charge cycle. The self-learning system eliminates unnecessary stress on the cells, resulting in an even longer battery cycle life.
The battery is MasterBus compatible, meaning they can be connected easily to a MasterBus system where you can operate and monitor all Mastervolt devices in one panel. In addition, they can also be linked via CZone / NMEA 2000 protocols.
