Specifications: Power Supply Voltage: DC 4.5-6V (micro USB connector) Operating Current: less than 70mA Discharge Voltage: 1.00V-15.00V; Resolution: 0.01V End Voltage Range: 0.5-11.0V Let-through Current: 30mA; Resolution: 0.01mA Voltage Measurement Deviation: 1%+0.02V Current Measurement Deviation: 1.5%+-0.08mA Battery Capacity Range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch; when it is less than 100mAh, the display is XX.XX; more than 100mAh, the display is XXX.X and so on. Board Dimensions: 50mm x 37mm Finished Product Dimensions: 50mm x 37mm x 17mm (length x width x height; copper foot height is counted) Metal film resistor kit included: 9pcs resistors(200: 3pcs 510: 3pcs 1K: 3pcs) Instructions: 1 The tested battery should be fully charged first. 2 Connect the tested battery to input connector's "+" and "" and you cannot connect it oppositely (connecting it oppositely may damage the circuit with load). Connect load resistance to 2 "R" connectors and power up the tester by micro USB (cannot be powered up by desktop or laptop's USB) and the display is battery voltage. 3 Start the test by directly pressing "OK" button and the tester can automatically set the appropriate end voltage according to battery fully charged voltage and end voltage blinks 3 times to start the test. If you want to manually set the end voltage, press "+" or "" before pressing "OK" button; end voltage display starts with "P" and its rest part is voltage value with 0.1V resolution ratio; press "OK" button to start the test after the setting. 4 The tester will connect the load controlling electronic switch after the test is started; the test process data display, discharge capacity (mAh) current discharge current (mA) and battery voltage (V) will take turns to display. When the battery voltage reaches its setting end voltage, the tester disconnects load controlling switch and the display data displaying capacity (mAh) blinks rapidly as its indicator light does; the displaying capacity is battery's real discharge capacity; press "OK" button to stop the blinking to get the static displaying data; press "OK" button again to recover to the very first being powered up status to change the battery to test the next one. Error code meanings: Err1: battery voltage is higher than 15V Err2: battery voltage is lower than setting end voltage Err3: battery cannot withstand load discharge current or wire is too thin or too long Err4: current is too high (>31mA) Package included: 1 x Battery capacity tester 1 x Metal film resistor kit

To the controllers with 12V/24V automatic identification function, 12V and 24V Battery Auto sensing.The short circuit, over-load, connection-reverse protection, as well as over-charge, over-dischargeprotection are available. Besides, the complete indications are usable, including indications for states ofcharge, storage battery and faults.Through the computer chips, the controllers take samples from the parameters of storage battery voltage,photo battery, discharge current and environment temperature, and then use the dedicated control mode calculation to control the discharge rate and make it matched with the characters of storage battery, realize the high accurate temperature compensation. PWM fuzzy charge mode and 7 phase voltage control are available for the storage battery, so that storage battery is always in the perfect working state .The various working modes of controllers can meet customers' different requirements.
