With this module you can test the capacity of a battery. By connecting a fully charged battery and starting the Ah test, the battery will slowly discharge while the module keeps track of how many Ah are available. For example, if you have a 18650 battery labeled 2,000mAh, you can test whether this is actually the case. Often, the indication on cheap Chinese batteries does not match reality.
Suitable for all types of batteries up to 12V (max. 15V)
Cutoff voltage adjustable.
Comes with 2 load resistors and screws.
- Power supply voltage: DC4.5-6V (power supply not included, recommended OTRONIC 5V Micro USB power supply)
- Operating current: no more than 70mA
- Discharge voltage: 1.00V-15.00V
- End voltage range: 0.5-11.0V
- Supported current: no more than 3.000A
- Voltage measurement error: less than 1% + 0.02V
- Current measurement error: less than 1.2% +- 0.008A
- Battery capacity range: 9999Ah
Note, an external 5V power supply with a micro USB connection is required to power the board. We recommend our 5V micro-usb adapter.

Works, as far as I can tell. It is a pity, though, that if you haven't pressed the buttons for a few seconds, the display switches on its own between voltage, current, and charge, and blinking lights indicate which of the three is being shown. The English manual was translated from Chinese by someone or something that does not master the English language.
Worth testing
The only thing missing is (a link to) the manual
