The self-heating function MUST be disabled or enabled uniformly on all the batteries in the
parallel battery bank.
The warning status will not affect the normal use of the battery. But it is recommended to
pay closer attention to the battery to prevent it from entering the protection mode.
The normal operation of the self-heating function requires a stable charge current greater than
3A for each battery in the parallel battery bank. The self-heating function will start operating
automatically once the battery and the battery temperature drops below 41°F(5°C) and stop
operating automatically once the battery temperature rises above 50°F (10°C).
