ZB2L3 Battery Capacity Tester 1.2-12V (OT5300)

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 drain while the module keeps track of how many Ah are available. Suppose you have an 18650 battery with 2,000mAh on the label, then you can test whether this is actually the case. The indication of cheap Chinese batteries often 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, advice OTRONIC 5V Micro USB power supply) - Working current: no more than 70mA - Discharge voltage: 1 00V-15.00V - End voltage range: 0 5-11.0V - Support via 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 Please note, an external 5V power supply with a micro USB connection is required to supply the board with power. We recommend our 5V micro-USB adapter.
