DIY Li-Ion Battery Capacity (mAh) Tester 

Love your layout very nicely done my good man :)

WOW, amazing job! Gelous ! Congrats !

I tested the batteries on xtarvc8 and then on these zb2l3 and the values ​​are close. I recommend these capacitors but it is good that the batteries are charged and discharged then measured again i like the video congratulation !

Well done, great video

Very nice👍

Good video 👍

Impressive 🙏👍😊

Excelente, bom trabalho. Parabéns

The video is interesting. I paused the video frame by frame and had fun with your creativity in writing the mah values. Completely different from what the display indicated... anyway...🤣🤣

Sir pls put your expert thoughts on OLA fire 🙏

Amazing😍👍

interessante o video. Pausei o video quadro-a-quadro e me diverti com a sua criatividade ao anotar os valores de mah. Completamente diferente do que indicava o display...enfim...

Super bro I like your video

а bms плата разве не нужна?! вы же не проверили все на напряжение 4.2 вольта! просто они же могли по разному заряжаться,ну а так все четко! идея КЛАССНАЯ)!!!!!

Nice

Amazing

Bhi big fan

Good, good man ❤

Hm osum idia..thx

Great video, thanks for the brilliant idea! I ordered 12 of them. What charger do you recomand to power them all?

cool as ....

Terima kasih.

Maybe invest in a new clean soldering iron with a good point on it... 😊

Bom dia parabens

Essas placas são fiáveis? Depois desse teste as células devem ter algum tempo de repouso? Obrigado

Inspiration for me

4:40 ligou invertido a bateria kkkkkkkkkkkkkkkkkkkkkkk 2:22 alguns modulos fixados com parafuso soberbo 2:32 outros modulos fixados com cola quente Resumindo... ideia boa mas muita gambiarra 🤣🤣🤣🤣🤣

where i can get this tester

What lithiam battary collect.

Excellent What power supply have you used Thanks

👍👍👍👍👍👍

What is the maximum AH capacity of each battery? thanks for sharring

What power supply have you used

Colar banaoge bai please,

Bhai yah capacity tester chahie Jo aapane banaya hai kaise milega

Wow🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉

25×2.40$=60$ only on the modules

Jajajaja amazing

I don't get accurate readings.🤔

You think is it DIY ? Realy ?

4.28 4.34 bro that is obviously not a good way to charge those cells. I would also be concerned about voltage drop along the path of the ZB2L3’s. They should be fine with 2A, they don’t draw much current but how low is the USB Micro voltage at the end of the string? I think min voltage is 4.0 but I wouldn’t be happy to see less than 4.5 on the last row just so that they don’t act funky during testing. Your cells also dropped in voltage significantly by the time you loaded all the cells in which tells me they did not spend enough time in the CV stage….or your bench power supply was feeding 4.35 volts and pulling them off early prevented most of the cells from truly retaining that overcharge. If the cell reads less than 4.15 it’s internal resistance is likely through the roof.

Very bad Idea. Do not copy him. The lower side of this Board is quite unsafe.

helo 2 sc

Bro make a some new

Phon no send karainn

Nice
