APPEARANCE AND LCD DIAGRAM
1) Power-down memory function:
in the charging process (constant current and follow-up stage), the product can re-
member the current charging mode after power outage, and restores the original
state when the grid resumes; the maximum time is 12h with battery connection.
In power-down memory state, the Power LED is on, the LCD doesn’t display,
and the backlight is off;
2) Charging mode:
identify 6V/12V batteries automatically; for 6V batteries, only 6V/1A SLOW mode is
available; for 12V batteries, three charging modes are available, as follows:
• 6V 1A /SLOW charging mode (default)
• 12V 1A /SLOW charging mode
• 12V 4A /FAST charging mode
• 12V 4A /LOW TEMP charging mode (Environment temperature <10°C)
The minimum voltages for automatic identification of 6V&12V batteries are 3V and
7.4V respectively.
3) Protection:
• Short circuit protection: keep or return to the initialization interface.
• Reverse polarity protection: the LCD displays reverse polarity signal
• Overheating protection
4) LCD display function
The product integrates LCD, as shown in Fig. 1. It displays the analog battery status,
charging mode, charging state, real-time voltage, and error message, and integrates
LED indicators. The specific LCD states are shown in Fig. 4 below:
a: reverse polarity icon
b: wrong battery icon
c: 12V battery icon
d: 6V battery icon
e: analog battery icon
f: slow mode icon
g: fast mode icon
