Lithium 18650 Battery Capacity Tester Internal Resistance Power Bank Storage Battery Test (Board+Fan)

Advantages:

- The original IR power tube, imported double ball bearing fan, and custom air duct radiator are used to ensure heat dissipation of the current-sense resistor and reduce temperature drift to ensure long-term stability. Power redundancy is not less than 50% (25℃).
- It can be powered by cellphone charger head Micro USB 5V port. Classic digital tube display is durable, outperforming LCD display. It has been tested before delivering.
- Parameter automatic memory function make is ideal for assembling power adapters for fully automatic aging cabinets or battery capacity testing.
- Accurate capacity measurement and small internal resistance measurement error.

Main Functions:
- MICRO Power Supply: Above DC5V 0.5A
- Tested Voltage: 0.1V-20V
- Voltage Error: <0.5%±0.02 (12-bit AD acquisition)
- Current Range: 0.1A-5A
- Current Error: <0.5% ± 0.02 (14-bit DA output)
- Capacity Range: 9999Ah 9999Wh 9999min
- Principle of Internal Resistance Test: DC pulse type test with ohmic differential compensation operation (pulse 3A)
- Internal Resistance Test Range: 999mR; Resolution: 1mR; Internal Resistance Test Error: <10%±1mR



Features:
- Support testing various batteries 1-20V
- Auto Identification Mode: It can automatically identify the battery type, automatically set the cutoff voltage and perform capacity test. In automatic mode, the battery needs to be fully charged before starting the test.
- Manual Setting Mode: It is user-friendly. You can adjust the cutoff voltage as needed.
- 3 Testing Modes: Two-wire period mode, two-wire continuous mode and four-wire mode can be switched to meet your needs.
- Multiple Protection & Diagnosis: Including protections for battery reverse connection, over-voltage, power tube damage, open circuit of discharge circuit, restart automatic operation, and replaced battery diagnosis.
- Parameter Settings: By parameter setting, it is possible to switch between normal test mode and high-current test mode. The normal test mode supports a discharge current setting of 0.1-2A. The high current test mode supports a discharge current setting of 0.1-5A, which is more suitable for performance testing of power batteries. The current can be adjusted arbitrarily every 0.1A.
- Power-Off Memory Function: All parameters, including the one being measured, are automatically saved. After the power is cut off, you can restore the scene and parameters as long as you re-power it.

Three Testing Modes:
- Two-Wire Period Mode: periodically cut off the discharge circuit and measure the battery voltage, which can effectively prevent the influence of the line loss voltage drop. In this mode, the battery voltage is measured at the moment of cutoff (within a few milliseconds) instead of the measured load voltage. It will be higher than the voltage directly measured by a multimeter.
- Two-Wire Continuous Mode: It is mainly used for electronic load testing. In this mode, the voltage of the load-carrying terminal is directly measured. Do not use this mode for battery capacity measurement, otherwise the results will be inaccurate. In this mode, when the battery is actually loaded, it can measure the battery power that the load actually uses.
- Four-Wire Mode: For professional measurement, special fixture is needed to accurately test battery performance.
