1S-8S 3.7V Lithium Battery Capacity Indicator Module 4.2V Display Electric Vehicle Battery Power Li-ion

1. Working voltage: 3-34V, working current 5mA.
2. Working temperature: -20~50℃
Voltage error 2% do not shoot if higher accuracy is required
Warm sound reminder: This model is not waterproof, if you use it outdoors, please do a good job of waterproofing because the electronic components need to be used in a dry environment.
Lithium-ion lead-acid nickel-metal hydride batteries can use the power display

board, as as the required voltage is within the range of the table.
How to use: Connect the positive and negative terminals of the display board to the positive and negative terminals of the battery under test, and the dial tube will display the real-time battery power.

1. Battery power display, select the corresponding pad to tin, you can detect the voltage of the battery pacorresponding to 1S-8S, which is very convenient.
S1- optional pads can only be connected to one type, and it is not allowed to have 2 or more short-circuit 1 lithium battery at the same time.

2. How to use: Connect the positive and negative ports of the display board to the positive and negative ports of the battery under test, and the dial display tube will display the real-time battery level. Note that several strings are connected in series
For the lithium battery, it is necessary to connect tin to the corresponding pad. For example, if you measure a 2S battery that is, two 3.7V lithium batteries are connected in series, you need to short-circuit the tin on the pad corresponding to S2 of the board.
3. Pay attention to select the corresponding number of battery strings, and use it within the corresponding voltage range. The maximum voltage should not exceed 4.3*N. For example, if the pad of S3 is tinned, the maximum voltage detected by the module should not exceed 4.3*3=12.9V

When the battery voltage is greater than Nx3.3V, it will light up for 1 grid Note: N represents the number of battery cells

Display power quantity s: Note: N represents the number of batteries
1 When the battery voltage exceeds N*3.3V, it will illuminate 1 battery
2. When the battery voltage exceeds N*3.5V, it will illuminate 2 pieces of electricity
3. When the battery voltage exceeds N*3.7V, it will illuminate 3 pieces of electricity
4. When the battery voltage exceeds N*3.9V, it will illuminate 4 pieces of electricity
5. When the battery voltage is less than N*33V, the 4 displays will be turned off
