The Zbms is one of the most popular choices as far as BMSs for the OneWheel go. Known as the “dumb” BMS, this BMS is sought after due to it not needing any programming, or data wires. It is as plug-and-play as BMSs get. This BMS does not offer any cell monitoring or VESC connection features, but don’t worry, this BMS is tried and true as one of the best options out there.
The ZBMS is seldom in stock, though it is recommended to get one if you can.
