Description
The Rock-12-120 lithium battery is safe and reliable whilst being small and lightweight, with long life and fast charging. Comparing the Rock-12-120 lithium battery with similar batteries, the volume and weight are around a third and a half respectively than that of ordinary lead-acid batteries. The build battery management system(BMS) provides multiple protection: over-charge, over-discharge, over-current, and over-temperature. The Rock-12-120 lithium battery will last at least 2000 full cycles before minimal performance changes. This means it can last up to seven years, depending on the frequency of use. It can also be charged and discharged under high currents without affecting its expected lifespan. The Rock-12-120 lithium battery can be used with solar inverters, vehicles, electricity grids, and many other charging methods. It is very suitable for use in various vehicles, such as electric boats, caravans, RVs, and so on.
The Rock-12-120 lithium battery support 100A continuous discharges.
Customers can parallel up to 4 of them in parallel, to make a 12v480Ahead system. The maximum continuous discharge rate will be 400A in 4 parallel scenarios.
