- Page 13 The self-heating function needs to be disabled or enabled individually on each battery in the parallel battery bank. The self-heating function will not be able to operate normally if a PWM charge controller or a small current battery charger is used to charge the battery at low temperatures. It is recommended to disable the self-heating function to prevent it from starting and stopping operation frequently and consuming the battery.
