Support for gel batteries, sealed batteries, Fluid batteries, lithium batteries and other different types
of battery charging procedures.
With a limited-current charging mode, when the battery plate power is too large and the charging
current is greater than the rated current, the controller automatically reduces the charging power
and makes it work at the rated charging current.
Support capacitive load instant high current start.
Support battery voltage automatic recognition.
Overheated protection.

Step 1: Fixed screw
First put the installation position guide board in the right position, then use a pen to mark
the installation position, drill 4 suitable size installation holes at 4 marks, and fix the screws.
Step 2: Fixed controller
Aim the fixed holes of the controller at the four screws fixed in advance and hang them to
ensure the safety and reliability of the controller.

V/24V/48V Automatic recognition).
Note:After the 36V battery system is turned on, the machine needs to be powered up again.
Or if the 36V battery system is already turned on and you want to another battery system,
you need to turn off the above operation and then power up the machine again.
