The voltage and percentage are linearly related. U-L corresponds to 0% of power, U-H corresponds to of power

Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.

Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!

Package Includes:

1 x Digital Voltage Battery Power Indicator (The default 12V lead acid)

About model selection:

[Factory default second-line lead acid 12v] You can use it directly on lead-acid 12V when you get it. If you use it in other batteries, please reset U-L (undervoltage) and U-H (full charge).

More settings are as follows.

For changes, please refer to the following method:

1. There is a high on on the back of the board. Pre the on for 3 seconds to display 1-U, release the on, pre 1 second to display UL, release the on, pre 1 second to display UH, release The on, pre 1 second. Display 4-d;

Second, when displaying 1-U, pre the on for 3 seconds, you can fine-tune the voltage measurement. At this time, release the on and pre it again. The voltage will be fine-tuned upwards. Pre and hold again, And then fine-tune it. You can adjust it repeatedly. Wait for the screen. Automatically save and exit ar flashing; generally no need to correct

The value is added, the stop is preed and Then the on is preed, the value is reduced, and the adjustment can be repeated ar the screen is blinking. Automatically save and exit. This voltage value corresponds to 0% of the power.

At the time, release the on and pre it again. The value is added, the stop is preed and then The long pre, the value is reduced , and the adjustment can be repeated ar the screen flickers. Automatically save and exit. This voltage value corresponds to of the power

5. When 4-d is displayed, the display mode can be adjusted, and the long pre can change the value. V is the voltage mode, % is the percentage mode, and the V% voltage and percentage cycle are displayed.

6. When 5-L is displayed, the power alarm value can be adjusted. At this time, release the on and pre and hold again. The value is added, the stop is preed and then long preed, the value is reduced, and The adjustment is be repeated repeatedly. Ar the screen flickers, it will automatically save and exit. The default is 10%. When the battery level is lower than this value, the alarm will flash.

7. Ar each adjustment value is set, wait until the screen flashes automatically to save and exit before proceeding to the operation, otherwise the new adjustment value will not be saved!

Setting example: Set up a battery-powered system. The lowest alarm voltage is 21v. The full voltage is 27.5V. The display mode is only showing the percentage.

Set as follows: select 21V in U-L, 27.5V in U-H, and % in 4-d;

Frequently Asked Questions: (Q & A)

1 : Power percentage and voltage Do you want to switch manually?

A: The default power percentage and voltage values are automatically displayed in turns and displayed in 2 second intervals. Users can also set their own fixed display one.

2 : I don't know how much my lithium battery is. How to buy it

A: Lithium batteries are generally divided into two kinds of lithium batteries: 3.7V/3.2v.

Lithium in the option is the default 3.7v (full charge is 4.2v) lithium battery. Look at the maximum output voltage of the charger/4.2V to get the number of strings. For example, the charger writes a maximum output of 54.6v. 54.6v/4.2V=13 strings. 12.6V/4.2v=3 strings. Lithium-free parallel connection.

3.2V lithium battery (full charge 3.6v). For example, the maximum output of the charger is 14.4v. 14.4/3.6v=4 strings. For 3.2v lithium battery, customers need to set it up.

3: I don't know my battery U-L, U-H is how much v.

A: The general approach is as follows

U-L is the battery undervoltage value, you can try to use up the power to finish the observation of how much voltage, v, set accordingly.

U-H is the full battery voltage, which can be filled with the charger. Ar the charger is unplued, the voltage v is observed and set accordingly.

4 : How to connect, use 2 lines or 3 lines.

A: The battery voltage is le than 30V using the 2-wire method. For example lead-acid 6v, 12v, 24v. Lithium 7.4v, 12v, 15v, 24v.

The battery voltage is more than 30V, using 3-wire mode. See the wiring instructions in detail!

Note: The product does not have leads and requires welding conditions.
