1-8S 1S/2S/3S/4S Single 3.7V Lithium cell Capacity Indicator Tester 4.2V Display Electric Vehicle Power Tester Li-ion
The power display panel can be used by lithium, lead acid, or nickel-hydrogen cells/power packs as long as the required voltage is within the parameter table range.
Working voltage: 3-34v
Working current 5mA
Operating temperature: -20~50 ℃
Voltage error 2%
Warm sound prompt: this model is not waterproof. If it is used outdoors, please do a good job of waterproofing, because electronic components need to be used in a dry environment.
Usage: Connect the positive and negative terminals of the display board to the positive and negative terminals of the power pack under test, and the nixie tube will display the real-time power pack charge.
Power pack type power display: Select tin on the corresponding bonding pad to detect the power pack voltage corresponding to 1S-8S, which is very convenient.
Only one S1-S8 optional pad can be connected; two or more short circuits are not allowed at the same time.
Usage: Connect the positive and negative ports of the display panel to the positive and negative ports of the power pack under test. The digital display tube will display the real-time power pack charge. Note that after connecting several series of lithium cells in series, it is necessary to connect tin to the corresponding pads.
For example, if a 2S power pack is measured (i.e., two 3.7V lithium cells connected in series), a short circuit on the pad corresponding to S2 of the board is required.
Pay attention to the number of corresponding power pack strings and use them within the corresponding voltage range. Do not exceed a voltage of 4.3N at most. (For example, if the tin on the pad of S3 is selected, the maximum voltage detected by the module should not exceed 4.33=12.9V)
The power pack voltage is greater than N x 3.3V, and the power pack voltage corresponds to 1 grid. (Note: N is the number of cell segments)
Display charge parameters: (Note: N indicates the number of cells)
When the power pack voltage exceeds N * 3.3V, it will illuminate 1 blockWhen the power pack voltage exceeds N* 3.5V, it will illuminate 2 blocks of chargeWhen the power pack voltage exceeds N* 3.7V, it will illuminate 3 blocksWhen the power pack voltage exceeds N * 3.9V, it will illuminate 4 blocksWhen the power pack voltage is less than N* 3.3V, the four display screens will be turned off, indicating that the power pack charge is less than 3.3V and needs to be charged.
