Availability: InStock
Rating: 5.00 (1 reviews)

The Harmony 32 is a high-power BMS which can manage up to 32 cells in series for batteries discharging up to 600A. An on-board ESP32 micro-controller running open-source VESC Software enables precise real-time monitoring and balancing of individual cell groups. VESC Tool enables complete flexibly to configurable all the parameters of the BMS so that the battery can be operated safely. With a maximum charge current of up 30A and real-time monitoring of cells, the battery can be wirelessly monitored while waiting for the battery to charge. This BMS also features short circuit protection up to 600A with a 10µs response time.

Isolated CAN-bus connectivity allows for seamless integration with other VESC devices for effective communication between all devices in the system. Other communication methods include USB-C, Wi-Fi and Bluetooth for convenient and flexible options to connect, configure and monitor the device using VESC Tool.

Suggested applications include small electric vehicles such as E-bikes, electric motorbikes, go-karts, trikes and buggies.
