    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. This BMS is for a 7S (25.9v nominal) lithium ion battery. It protects against over- and under-voltage as well as over-current, and ensures that the cells are balanced.
    To wire, you will need to battery and charge/load ground the 10AWG wires attached to the board. You will also need to tie each of the balance leads into the individual battery cells. Note that this has a common charge and load connection, not separate as some boards have. Balance wiring is not shown, but is included.
    This BMS is suited for smaller projects, but don't expect it to be adequate to protect a large build such as an off-grid power wall. This is perfect for eBike and scooters up to 1000 watts, as well as RC projects. And the case is waterproof, so you can ride anytime, anywhere.
