ZB2L3 battery capacity tester discharge type 1.2-12V external load capacity of the battery and other tests 18650
Tools, single-function, by controlling the load off and get real-time integrated discharge current capacity results
Maximum support 15V 3A discharged through the discharge voltage and current, itself does not discharge
Maximum capacity statistics support 9999Ah (9999000mAh)
Automatically identify and develop appropriate battery termination voltage can also be manually adjusted
Specifications:
Power supply voltage: DC4.5-6V (micro USB connector)
Operating Current: less than 70mA
Discharge voltage: 1.00V-15.00V 0.01V resolution
Termination voltage range: 0.5-11.0V
Supported by current: 3.000A 0.001A resolution
Maximum voltage measurement error: 1% + 0.02V
Maximum current measurement error: 1.5% + - 0.008A
Maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch, when the display is less than 10Ah X.XXX, as shown above to achieve 10Ah XX.XX, and so on.
Board size: 50mmX37mm
Finished Size: 50mmX37mmX17mm (length X width X height maximum position size, contains copper foot height)
Instructions:
1. The first test should be fully charged battery.
2. Connect the battery to be tested positive to positive input, a negative input to the negative, can not be reversed (with load reversal may damage the circuit)! Load connected to the output of the positive and negative output, to work through the tester micro USB power supply (not available desktop or laptop USB powered), then the battery voltage.
3. Direct start test need only one press of the 'OK' button, the tester can automatically develop an appropriate termination voltage of the battery full charge voltage, and will start flashing after the test three times. Need to develop artificial termination voltage only when the battery voltage display state by pressing '+' or '-' buttons to modify the termination voltage display beginning with P, behind the representative voltage resolution 0.1V, set up after pressing the 'OK 'start testing.
4. After the start of the test the tester will control the load of the electronic switch is turned on, the test data shows that the process will release capacity (Ah), current discharge current (A) and battery voltage (V) between the wheel was. When the battery voltage reaches the set cut-off voltage, load control switches off the tester display data stays in capacity (Ah) and above and the corresponding indicator flashes quickly together, now displays the actual capacity of the battery is discharging capacity, about the press 'OK' to terminate flashing allows stable data display, press again 'OK' button to return to the power-on state can just replace the battery test the next section ......
Error codes and their meanings:
Err1: battery voltage is above 15V
Err2: battery voltage is lower than the termination voltage
Err3: Battery can not afford to load or discharge current line too much resistance
Err4: overcurrent (current exceeds 3.1A)
Note:Use the resistance of the discharge process, resistive load will seriously heat, please pay attention to safety!
This circuit voltage in order to improve the measurement accuracy, specially designed DC bias, when the terminal displays nothing then a small voltage does not affect the actual measurement, if you are shorting the input terminals (absolute 0V) will show 0
Method of use:
1. The battery under test should be fully charged first.
2. Connect the positive electrode of the battery under test to the input positive electrode, and the negative electrode to the input negative electrode. Do not connect the negative electrode with the load, which may damage the circuit. Connect the load to the output positive terminal and output negative terminal, and supply power to the micro USB of the tester (USB power supply of desktop or laptop is not available). The battery voltage is displayed.
3. Directly start the test only need to press the 'OK' button, the tester can automatically set the appropriate stop voltage according to the full charging voltage of the battery, and will flash display 3 times before starting the test. To manually set the stop voltage, only press the '+' or '-' button in the battery voltage display state to modify. The stop voltage is displayed at the beginning of P, and the following represents the voltage value, with 0.1V resolution. After setting, press 'OK' to start the test.
4. After the test begins, the tester will switch on the electronic switch to control the load, and the data in the test process will be displayed between the release capacity (Ah), the current discharge current (A) and the battery voltage (V). When the battery voltage reaches the set termination voltage, the tester cuts off the load control switch, and the display data stays on the capacity (Ah) and flashes quickly together with the corresponding indicator light. At this time, the displayed capacity is the actual discharge capacity of the battery. Press 'OK' to stop flashing and make the data display stable. Press the 'OK' button again to restore to the just powered on state you can replace the battery test Next......
Error codes and their meanings:
Err1: The battery voltage is higher than 15V
Err2: The battery voltage is lower than the set stop voltage
Err3: The battery cannot withstand the load discharge current or the line resistance is too high
Err4: Excessive current (current exceeds 3.1A)
Err5: Improper use or wiring error has caused the device to burn out and cannot be used (current sampling or control switch MOS burned out)
