We offer select Battery Management Systems (BMS) for use in e-bike batteries in all common e-bike voltages: 24v, 36v, 48v, 52v, and 72v. The 12v BMS is more meant for trolling motor systems on canoes and kayaks, as well as small, off grid DC power systems like a weather station, phone charging system, or hydroponic controller.
They are manufactured by Daly in China, and have an excellent build quality for the price. Our BMSs all allow simultaneous charge while discharging, which is essential for any solar EV or powerbank application. These BMS units can come in handy for repairs or DIY battery packs. Make sure the rating of your lithium battery cells exceeds the capacity of the BMS before purchasing the unit. If you want to learn more about BMSs, click here.
