The ship battery is made of lithium-ion cells and therefore the battery is part of battery monitoring (BMS).
The "BMS" function of all battery cells is responsible not only for the calculation of battery charge (SOC), but also to protect the battery against overcharging, deep discharge, overheating and short-circuiting.
When the battery pack power switch is turned off, the battery becomes self-discharge and the storage capacity is extended.
The battery pack has two communication ports. One is used to transmit battery status, which can be read on the NAVY engine's LCD and the other for communicating with other connected batteries.
Due to the physical and thermal protection of battery cells, the battery case is a high-strength extruded aluminum.
Generally, a battery is required for NAVY 3.0 and two are required for NAVY 6.0 simultaneously.
