The datasheet mentions that voltage regulation is offered by the BMS 12/200, but it doesn't go into any detail about it: "3. Excessive input voltage and transients are regulated down to a safe level." Does anyone know more about how voltage is regulated, the limits, and if it's programmable? All I've found is that the approximate cutoff voltage is 11V.
