Battery Capacity Meter, 12 Volt with blue backlit LCD display, and percentage measurement

Battery capacity meter for accurate measurement of your battery

If you use solar panels with a charge controller without a status display such as voltage and percentage, this battery capacity meter is an ideal tool to see how your battery is doing. The meter has a green backlight that is always active so that you can also see the status in the dark.

Setting procedure:
1. Disconnect the module power supply, press and hold the setting button next, power on module. Display shows the current power setting parameters;
2. Press the setting button to select P / L / F ,

P = 12V lead acid,
L = 3.7V lithium battery,
F = 3.2V lithium iron phosphate battery);


3: Press the function key (S1) to set the number of the battery strings, according to the function keys and set the key up or down to choose the number of batteries in series;
4: Press the function key (S1) for a long time to enter the advanced setting interface, use setting key to select S1-S5, enter key to select or cancel the current mode;
5: Reenergize the power after setting. The power automatically saves setting data.


E.g. 10 lithium battery power, turn on power percentage and voltage automatic rotation display (S1 mode)
Operation: Disconnect display module power, press and hold the setting button, power the power module, press the setting button for a short time to select L, press the function key to select 10, press the function key for a long time to select S1 and re-power.

The own energy consumption of this meter is very little with only 15mA, the meter can be called energy-efficient
