11.4~12.8/22.8~25.6/34.2~38.4/45.6~51.2V (default : 12/24/36/48V). SC-MAX series can not set LVD, its LVD is 0.8/1.6v higher than LVR by default. 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, than LVR must improved first. - Page 16 6.3.4 Batter y type When the LCD shows as displayed at left, press the MENU key for 1s,the icon flashes , you can set the batter y type. Display Batter y type GEL(Default) Liquid Lithium 1.Charging Voltage Parameters(Liquid, GEL, AGM) When choosing Liquid, GEL or AGM for battery type, the parameters of boost, equalization and float charge voltage can be set by RS485 or bluetooth APP.
