6.4.1 Low voltage protection
When the LCD shows as displayed at left, press the MENU key for 1s, the
icon flashes, now you can set the controller's low voltage protection.
1. Lithium Battery
Low voltage protection setting range:
12/24V: 9.0-30.0V (default: 10.6V)
12/24/36/48V: 9.0-60.0V (default: 21.0V).
2. Liquid, Gel and AGM Battery
Low voltage protection setting range：
10.8~11.8V/21.6~23.6/32.4~35.4/43.2~47.2V (default:
11.2/22.4/33.6/44.8V).
6.4.2 Low voltage reconnect
When the LCD shows as displayed at left, press the MENU key for 1s, the
icon flashes, you can set the controller's low voltage reconnect.
1. Lithium Battery
Low voltage reconnect setting range is:

12/24/36/48V: 9.6-62.0V (default: 22.4V).
2. Liquid, Gel and AGM Battery
Low voltage reconnect setting range：
11.4~12.8/22.8~25.6/34.2~38.4/45.6~51.2V (default: 12/24/36/48V).
The low voltage recovery voltage (LVR) should be higher than the low voltage protection
voltage (LVD) at least 0.6/1.2/1.8/2.4V. If it is desired to improve LVD, then LVR must improve
first.
