1-8S 1S/2S/3S/4S Single 3.7V Lithium Battery Capacity Indicator Module 4.2V Display Electric Vehicle Battery Power Tester Li-ion
Operating voltage: 3-34V, operating current 5mA.
Voltage error 2% (higher accuracy requirements do not shoot)
Warm tips: this section is not waterproof, if used outdoors, please do a good job of waterproof.
Because the electronic components need to be used in a dry environment.
Lithium lead-acid nickel-metal hydride batteries can be used in the power display board, as long as the required voltage is within the range of the parameter table.
voltage within the range of the parameter table can be.
The digital tube will display the real-time battery power.
battery-type power display, select the corresponding pad on the tin, can detect
1s-8S corresponding to the battery pack voltage, very convenient.

S1-S8 optional pads can only be connected to a kind of, not allowed to
Allow 2 or more shorted at the same time.

Usage method
1.Connect the positive and negative ports of the display board with the positive and negative ports of the battery under test.
The digital display tube will show the real-time battery power.
Note that the connection is a few strings of series-connected lithium batteries, it should be in the corresponding lithium batteries, it is necessary to connect the corresponding pads on the tin.
For example, if you are measuring 2S batteries (i.e. two 3.7V batteries) battery (i.e., two 3.7V lithium batteries in series), you need to be in the board’s S2 corresponding to the pads on the tin short circuit. pad on the board corresponding to the S2 short circuit.
2.pay attention to select the corresponding number of battery strings, to be used in the corresponding voltage range.
use. Do not exceed the maximum voltage of 4.3*N. (For example, if you select the pad of S3 tray, then the maximum voltage detected by the module should not exceed 4.3*3=12.9V)
Battery voltage is greater than NX3.3V, light up 1 cell of power
(Note: N is for the battery N is the number of sections)
Display power quantity parameters: (Note: N represents the number of batteries)
1. When the battery voltage exceeds N*3.3V, it will illuminate 1 block of power
2. When the battery voltage exceeds N*3.5V, it will illuminate 2 blocks of power
3. When the battery voltage exceeds N*3.7V, 3 blocks of power will be illuminated.
4.When the battery voltage exceeds N*3.9V, it will illuminate 4 blocks of power.
5. When the battery voltage is less than N*3.3V, 4 displays will be turned off, and the meter will be closed.
