short circuit the positive and negative pole of battery.
Suggest to adding a fuse between battery and
controller. (Slow motion type, the action current of the
fuse should be 1.5 times rated current of controller.)
The controller could detect the temperature of
environment to adjust the voltage of charging, so that
the controller should be closed to battery as near as
possible.
Recommend system current density of cables less
Try to use multi strand copper wire in order to
connecting with the terminal firmly. Loose power
connection and/or corroded wires may result in
resistive connections that melt wire insulation, burn
surrounding materials or even cause fire.
The battery should be full charged each month. Or the
battery will be destroyed.
