DIY Li-Ion Battery Capacity (mAh) Tester

[@MarianCobirlie]

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 !

[@Sharpfxscalper77]

👌

[@jcolivie]

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...🤣🤣

[@jcolivie]

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...

[@Willalvers]

Love your layout very nicely done my good man :)

[@user-cc7dh5kq2n]

Well done, great video

[@krish_machinology]

Sir pls put your expert thoughts on OLA fire 🙏

[@lalado6969]

WOW, amazing job! Gelous ! Congrats !

[@guardiao_das_riquezas]

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 🤣🤣🤣🤣🤣

[@skajijul7519]

Very nice👍

[@furik261]

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)!!!!!

[@qnedim3200]

You think is it DIY ? Realy ?

[@oljobo]

Impressive 🙏👍😊

[@farzanarahman3591]

Hm osum idia..thx

[@tompelbogel]

Terima kasih.

[@orlatris96]

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

[@josuedanielmartinezsanchez4540]

Puedes verificarlo poniendo un amperimetro en serie con la carga (la resistencia de 5 watts. mides el tiempo y haces el calculo corresopndiente.. tedebe dar el mismo numero o uno muy cercano.. sino, podrias tener algun problema

[@orlatris96]

@@josuedanielmartinezsanchez4540 obrigado pela resposta. Vou copiar o teu projecto. Se possível diz que fonte de alimentação usas para alimentar as 25 placas. Um abraço obrigado

[@dragosbogdanmuntean8556]

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

[@ericklein5097]

A proper charger. Xtar VC8 is a great charger and 4 slots do a capacity test (but only at 300mA because the charger doesn’t have a fan and would struggle to dissipate the heat). The charger can also put your cells into storage. Just select the storage mode and pop in any cell at any voltage. It will go up or down to get to 3.7V (charging up causes a slightly higher voltage than discharging, discharged cells end up around 3.64 which is actually a better storage voltage IMO)

[@dkbhai7825]

Good video 👍

[@orlatris96]

Excelente, bom trabalho. Parabéns

[@mdaslamknl]

Excellent What power supply have you used Thanks

[@bobcatt2294]

I am also awaiting the answer to your question.

[@mwsparky2]

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

[@user-cc7dh5kq2n]

Super bro I like your video

[@muhammadmurtaza6443]

Bhai yah capacity tester chahie Jo aapane banaya hai kaise milega

[@mdsajimhossain8834]

[@Maxttor]

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

where i can get this tester

[@user-dt5gw6hz3v]

Good, good man ❤

Colar banaoge bai please,

[@waheex]

cool as ....

[@valtersouzaribeiroribeiro9534]

Bom dia parabens

[@TheMrjogas]

I don't get accurate readings.🤔

[@ericklein5097]

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.

[@ThanatosUA]

ZB2L3 working from microusb 4.5-6v Each one need 70mA. 25 of them need 1750 mA, 2A charger will be enoughf

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