Module Highlights:
1. Support battery and Acting Battery,voltage range:6V~60V;
2. Can display voltage,percent of battery,charging time at the same time through LCD;
3. The function is very powerful,realizes the automatic charge control,
the control charge time, also may set up and uploads the corresponding parameter through the serial port;
Function description
1. Automatic Charge control function:

By setting the volt-HI:'UP' volt-LI:'dn';When the battery voltage is below the volt-LI:'dn',the relay,the charger begins to charge the battery;when the battery voltage is up to volt-HI:'UP',the relay is diconnected and the automatic charge is completed once;
2. Charge Time Control Function:
How to turn on the time control function?
After entering the parameter set, set the parameter op is non-zero, then turn on the time control function, op default parameter is:--:--h, the default does not turn on time control function;
After the opening Time control function (OP is non-zero), when the battery voltage is the lower volt-LI'dn', the charger began to charge the battery, the system began to clock; During the timing, the battery voltage ≥ volt-HI'UP', relay disconnect; If the OP time is up, the battery voltage is still the lower volt-LI'dn', the relay keeps the conduction, automatically closes the charge time control function, and flashes the H:ER to remind the user, the time parameter setting is unreasonable; Press any key to stop flashing;
Note: Time format: 00:59 (00 for hours, 59 for minutes) The maximum time is 99:59, which is 100 hours.
3. Serial data upload and parameter setting function:

The system supports UART data upload and parameter setting
UART:115200,8,1
Cmd:Func
on: Relays enable to open
off: Relays disable to open
start: Start data upload
stop: Stop data upload
read: Read the param setting
dw10.0: Set volt-LI:'dn'
up20.0: Set volt-HI:'UP'
xx:xx: Set the charge time OP 00:00 stop charge time

Data Upload message Format:
Battery voltage + battery percent + charge time + charge status 12.0V,020%,00:10,OP

Parameter Setting
a) Press and hold the SET key to enter the setting interface;
b) Switch the parameters you want to set by short press SET;
c) After the selection of parameters, can be set by the UP/DOWN key to support the short press, long press (fast increase or decrease); To set other parameters, repeat step b, c);
d) After all parameters are set, long press set key to exit and save;
The Key Function Description:
In the Run interface (main interface):
Short press SET button to display the current set of parameters; Short press UP button, toggle display charge percentage and charging time;
Short Press DOWN button, select Turn on/off relay enabling, if the relay can be closed, will show ' off ' as a reminder;
Long press UP button, switch low power state
on:No operation in 10 minutes turn off backlight
OFF: Backlight is always bright
Long press SET button,enter the parameter settings.

Calculation of voltage percentage:
voltage percentage = battery voltage/(volt-HI – volt-LI)
Additional Features
a) Charging time recording function: not open charging time control, the product will record a full time, when the entry time display interface, flashing display charging time, and then exit time display interface or next charge to open (relay conduction) when empty;
b) Automatic parameter detection: When the parameters are set, exit, if volt-LI dn≥ volt-HI UP, the system will flash display "ERR" as a reminder;
c) Battery Access detection: This product attached to the battery, if not connected to the battery, the system will be shown in the downlink "NbE" as a reminder
