Specially used to measure capacity. The integration of charging and discharging eliminates the operation of disassembling and assembling the battery to replace the charging and discharging of the device.The size of the discharge current can be switched and it is convenient to use. Small size, easy to carry. stable performanceThis product is a capacity tester, which is specially used to measure the capacity of 18650 batteries. The 1.77-inch TFT display can simultaneously display information such as battery internal resistance, capacity, voltage, current, power, etc.;The operation of charging and discharging equipment; preset three modes of automatic, charging and discharging, after selecting the corresponding mode, the equipment, and the will run automatically; the size of the discharge current can be switched for .Technical parameter:Install the power supply and the to be tested;Use the Type-C data cable to connect the Type-C power supply port to the 5V power supply. The external power supply is used to charge the battery in the state. If you only need to discharge the , you can leave it unconnected;Select the mode, the default is AUTO automatic mode;Click the button to the ;Wait for the process to end and the status indication to stop.About power-off storage:This product has no power-off storage function. Shutting down, restarting, and switching the working mode can cause the accumulated data to be cleared It can be used The working mode corresponds to the state changeProduct name: capacity internal resistance tester charging and discharging integrated versionWorking voltage: DC5VDetection voltage: less than DC5VCapacity measurement range: 0~99999mAhEnergy measurement range: 0~99999mWhBattery internal resistance measurement: support, measurement error is about 10%Display real-time voltage: supportDisplay real-time current: supportDisplay real-time power: supportLog run time: supportWorking mode indication: supportCurrent Status Indication: SupportedSimultaneous discharge: not supported (simultaneous discharge of Test and external power supply Test is not supported)Discharge load: 10W 8J cement resistance x 2Discharge current : 0.5A or 1ACharging interface: Type-CExternal discharge interface: Type-CPreset discharge stop voltage: 3V (not adjustable)Preset full stop voltage: 4.2V (not adjustable)Colour:greenMaterial:plasticPackage Contents:2 x Battery Power Detector ModuleOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
