    ATTINY841 BMS

    ATTINY841 BMS thumbnail
    DIY BMS using ATTINY841-SSU this hardware has a higher balance current, fuse and TVS diode to help with voltage spikes. Most importantly, an external crystal to the micro controller (attiny841) which means the device is more reliable in low voltage situations
