ZB2L3 BATTERY CAPACITY TESTER

Link to buy - s.click.aliexpr....
- amzn.to/36fDfDX
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)

Short and effective, here´s my like

[@KoolBreeze420]

Could you not use say some 12v pc fans or something to make the load? Does it have to be these resisters and does it have to be 2?

[@SAI_LINGESH]

Instead of that two "5w 7k5 ohm load resistor" can I use alternative loads? Like bulb/motor/anything else which drinks so much energy as load?

[@ElectroRetro]

Yes

What does mean if code err2(error) come out? I have chacked voltage battery using multimeter 3.8v but when using this tester pop up code err2

[@ElectroRetro]

According to the description of zb2l3, Err2:The battery voltage is lower than the set termination voltage

[@mastergne1423]

@@ElectroRetro i see. So i need to recharge and test again right? Normal discharge voltage is 2.5v right?

[@ElectroRetro]

Maybe you set the termination voltage higher. To start the test with the automatically determined termination voltage, press the “OK” button. The display will flash the termination voltage 3 times and begin testing. If you wish to set the termination voltage yourself, press “+” or “-“ to modify the termination voltage as desired, then press “OK” to start the test.

[@mastergne1423]

@@ElectroRetro its working now. Buy when i set termination “P2.7” the last voltage stopped at 3.0v what does mean that? Why he not stop at 2.7v?

After stopping the test at 2.7v. The battery voltage may rise to 3v.

did I see "after 2 hours"? Is that how long to test the capacity of one battery?

According to the capacity of battery. Low capacity battery takes less time and high capacity battery takes more time.

[@BuluBuridSMDA]

Hi bro .. Want to ask about this module .. In terms of finding the real/original capacity on one 18650 battery, what is the most accurate load size to use? What's the maximum load that can be used or handled? 1 Amp or 2 Amp or 3 Amp? Thanks 4 answer & greeting from Indonesia ..(^_^)/

[@ElectroRetro]

I discharge 18650 batteries at 1amp of load. I use couple of 5w 7.5 ohms resistors in parallel to get 1amp. The maximum discharging current of this module is 3amps.

[@machtundrebel3127]

@@ElectroRetro Thanks for this straight to the point performance! Exactly what I wanted! So in order to set the discharge rate, I have to set a certain resistor? Is there a manual which resistors to use for which rate? Thanks

@@machtundrebel3127 if you buy this module you can get 2× 7.5 ohms 5 watt resistor. You can use 1 resistor for 500ma discharging current or use 2 resistors in parallel to get 1000ma. thanks for watching

[@ElectroRetro]

It's not made to test low voltage batteries, although it supports it. Can't guarantee the accuracy.

[@zbeat2045]

DO NOT BUY THIS PIECE OF CRAP. It can measure voltage fairly well but it can't accurately measure current. My testing shows 705% error at 1.0V, it gets better at higher voltages, 27% error at 3.5V. Measuring current is the primary thing this device needs to do for a battery capacity test and this device can't do it.

[@stafiejulien]

What do you recommend then ? There is something better then this little board?

[@ricksummerfield784]

I found they drift out of calibration, some after only a few cycles, so not super great if you have hundreds of cells to check
