DIY 4 x 18650 Battery Capacity Tester

Please make a review video on the soldering iron

Looks like a suicide bomb...

please make the gerber file for this. just like DIY 18650 charger. it will be awsome...

All you literally did was stick a couple premade battery testers onto a piece of plastic.
Its pushing the limits of what's called making.

Hello, do you know wich kind of resistors i have to use for testing a 12V Akku? The two 5w getting too hot

What type of screw need that board? M3 ?

i have 4 too , device are badly constructed, they dont tell us baterry capacity left, you get only range how many current resistor spend util voltage drop down at set,, also you can try discharge with 10 ohm resistor and you will get another Ah value

which cable size you used on this proj.???????

Nice video. Thx.I bought this same tester and it came with two resisters marked ZY 5W7R5 . I used only one resister and tested my havested good batteries showed before charging 3v- 4v readings. But after almost one hour draining the batteies this tester showed mah readings made me frustrating. They are 0150, 0337, 0341, 0362, 0507, 0509, 0511, 0622, 0648, 0962, 0995, 1001, 1094, 1096,1425,and 1598. Are these my real capasity of my batteries or have to understand or how to read this readings? Thx for your reply to send me or correct way.

I am interested to make a testing board like yours. But I couldn't undertstand how you did give the power to all 4 micro USB plugs. Can you please explain that.

What is the meaning of error 2 and error 3????

Is it okay if I parallel 5 of that? Also can you give me a link for those screws that you use on battery holder?

will these modules also charge?

You should try to make more unit an sell it on ebay

I have only capacity tester I dint get 5w 7.5ohms ceramic resistors ,what can I use it alternative for it .

So there is not a capacity tester with more than one cell test at a time?

This is great, could you make a pcb design like your single discharge tester but with 4 like this? I am waiting on the parts for my 80 bay tp4056 charger and would like to start working on a 40 bay discharge tester.

Hi Steve, good video, looking to build one myself. Can you comment on how accurate you have found discharge capacity results from these ZB2L3 tester boards to be, similar ones can be pretty inaccurate eg see vidoes by KainkaLabs thanks.

Hi. Is there a way to bulk test batteries? Ive got about 100 old laptop batteries to test.

Try Zanflare LCD display smart charger Zanflare C4, specifications
- Input: AC 100 - 240V, 50 / 60Hz, 0.6A max, DC 12V, 1.5A
- Output: USB 5V 2A
- Charge current: rechargeable Li-ion batteries 4.2V, 300mA / 500mA / 700mA / 1000mA, rechargeable Ni-MH batteries 1.48V, 300mA / 500mA / 700mA / 1000mA
- Discharge current: 300mA, 500mA

Do you need to Set the low voltage cut off every time ( USB disconnected )

Toooooooo slow wasting time

.

Nice

good morning
why not use PCB boards?

good morning
you offer the JLCPCB site but you don't use a PCB board... why?
thank you

Sal am, au début on a besoin du schéma du circuit ensuite tu explique étape par étape lentement Merci

I have 6 of this my problem is the outcome of test is very far fron lii500.

Cool!!! Like & subscribe!)
