[vc_row][vc_column][vc_tta_tabs][vc_tta_section title=”Description” tab_id=”description”][vc_column_text text_larger=”no”]ZB2L3 is a simple, cheap, standalone battery capacity tester. It connects to the battery and a load resistor. This module can discharge the battery by drawing current to the high wattage resistor. By calculating the discharging current, time and others parameter it can measure the capacity of a battery. The discharging limit can be set by user. This module has a 4 digit 7 segment display which shows different parameter like volts, current and capacity of the battery. The module is powered by 5v and has a micro usb port to connect the power cable.

Note:

Using the resistance of the discharge process, resistive load will seriously heat, please pay attention to safety!
Please install the 50W aluminum resistance (has been soldered half part of high temperature line) to a metal plate to use!
This circuit voltage in order to improve the measurement accuracy, specially designed DC bias, when the terminal connects nothing will display a small voltage, but does not affect the actual measurement, if you are shorting the input terminal (absolute 0V) will display 0. If you want to know the principle, you can check the superposition theorem of electrical engineering.

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 discharge current or the circuit resistance is too high
Err4: Overcurrent (current exceeds 3.1A)

Package includes:

1 x ZB2L3 Battery Capacity Tester Module
2 x 5W 7.5Ohm Resistor[/vc_column_text][/vc_tta_section][vc_tta_section title=”Specification” tab_id=”specification”][vc_column_text text_larger=”no”]

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 current: Maximum 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 is switched by shifting the decimal point, when it is less than 10Ah will display X.XXX, up to 10Ah or more will display XX.XX, and so on.

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 ……
