ZB2L3 Battery Capacity Tester 1.2-12V

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
