ZB2L3 BATTERY CAPACITY TESTER

[@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

Hi! Can I check 18650 20A-30A batteries with this?

[@ElectroRetro]

Yes

[@ervivekchoubey]

Can we use 21700 Li-ion cells instead of 18650?

[@ElectroRetro]

Yes

[@aaroncatolico7550]

*Does this have any type of automation for a charge, discharge, & then charge again or just strictly manual settings?*

[@ElectroRetro]

@@aaroncatolico7550 No automation

[@heklik]

Why do you need to put 2 5w resistors ?

[@ElectroRetro]

It's a load resistor

[@rahamathullahabdulkather9147]

What are the type of batteries I can test (Lead acid,Nicad, Li-ion)

[@ElectroRetro]

Yes, you have to set the cutoff voltage according to your battery

[@mario04549]

Sir can i use 5w8.2ohm resistor on this module for 18650 battery

[@ElectroRetro]

Yes you can use it. The discharging current will be about 500ma if you 8.2ohms resistor.

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?

[@ElectroRetro]

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

[@lambo-san]

Is the Ah is the same as mAh?

[@ElectroRetro]

1Ah = 1000mAh

[@yuliant0225]

Can it be used to lead acid battery ?

[@ElectroRetro]

Yes

[@vcys2]

I have got my unit, I put it on and test my 3.2v lifepo4 batteyr, after runs for few minutes, I touch the white register, it is very hot to touch... was it normal ? It is save to carry on for few hours ?

[@ElectroRetro]

Yeah, it's normal. If you want You can add a small cooling fan.

Sir how to check mobile battery capacity? By this module

Maybe 3v I don't know exactly.

can you make 15ah tester? will that support?

[@davidjesse8689]

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

[@ElectroRetro]

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

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

[@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

[@ElectroRetro]

@@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

Can i use different resistor

Yes, but the current will be different

[@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

[@jopalzm1]

@@ricksummerfield784 That's right, one battery measures 2500 mAh once and 375 mAh the second time after charging. It's totally wrong!
