Description
A battery management system (BMS) is essential in a lithium ion battery build. Li-ion batteries are much more sensitive to voltage than lead acid, and can be dangerous if over- or under-charged. It protects against over- and under-voltage as well as over-current, and ensures that the cells are balanced. This BMS is for an 20S (72v nominal) lithium ion battery, and allows 100 amps continuous discharge and 50 amps charge. That's7200 watts
of continuous power*. Wow!
*It is highly advisable to over-size your BMS to minimize the chance of failure. Thus, while this is technically able to handle 100a continuous, we HIGHLY recommend purchasing a larger BMS if your application regularly calls for 100a.
The board comes with wires to connect battery negative and charge/load negative. You will also need to tie the included balance leads into the individual battery cells. Note that this does NOT have provision for separate charge and load, as some boards do. Balance wiring is not shown, but is included.
The balance function is suited for smaller projects, but don't expect it to be adequate to balance a large build such as an off-grid power wall. This is perfect for eBike and scooters, as well as RC projects. And the case is waterproof, so you can ride anytime, anywhere.
