If you are planning to run a 21s battery please do not use regenerative braking. This will create back EMF (voltage spikes) Higher than the ratings on the components.

When using ADC analog inputs, do not exceed 3.3v (If using ebike throttle, power from the 3.3v instead of the 5v)  Using above 3.3v can possibly damage the controller. If confused about this, reach out to support with questions.
