Battery Management System

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 a 14S (51.8v nominal) lithium ion battery, and allows 30 amps continuous discharge and 20 amps charge. That's 1500 watts of continuous power. Wow!
The board comes with 10AWG wire to connect battery negative and charge/load negative. You will also need to tie each of the 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 eBikes, scooters, go karts and other higher-power builds. And the case is waterproof, so you can ride anytime, anywhere.

We ship the majority of our orders by the next business day. Lithium batteries may take up to two business days to process to accommodate inspection and logging into our system.

Our shipping rates are based on the weight of all ordered products plus estimated weight of packaging. We make every effort to forecast an accurate shipping cost, but cannot be 100% certain in all cases. Please contact us at sales@higherwireenergy.com with any questions prior to purchase.

We pack and label all lithium battery shipments in accordance with Federal Regulation 49CFR173.185, as well as USPS Publication 52 Hazard Class 9 or UPS/Fedex guidelines. Unless otherwise stated, lithium batteries are not eligible for free shipping.

We try to pack all items in an order in a single box, however we may on occasion need to ship items separately. Special shipping does not apply to lithium ion batteries, and orders that include batteries may not qualify for free or expedited shipping.
