12v battery pack 18650 lithium ion 3s7p

[test-]

Please look up why there are gaps on the nickel strips (over each cell).

Those gaps serve a purpose, that you are not using correctly.

Also, always check the voltage on cells that you are wiring in parallel. Don’t assume that new cells will all be charged to the same voltage when you receive them.

Another issue: when connecting the BMS board, you should start with B-(ground), then B1 (4.2V), then B2 (8.4V), then B+(12.6V).

Wow, the battery terminals are in danger of shorting out your cells. Perhaps some kapton tape or an insulator to prevent this?

The charger you are using is only 0.5 Amps. At that rate, each cell in the 7P parallel arrangement will only see about 70mA. For a 2500mAh cell, that would take 35 hours to charge.

sana lagay din sa description yung mga pyesa paps. pra may guide kami

Hello. where did you buy the cells, and how much did they cost? thank you in advance

[fatsalda]

What is the capacity of each battery and how many amperes is the final power?

[fernandofrediani]

Hello there
I have replace my no break battery by a Lithium one similar to that.
However as the nominal voltage is 11.1V, when it reaches that the no break starts to beep quicker thinking that it is near out of charge, but it is not.
Anything that can done about that ?

Sir spot welding machine ka video banaiye sir

[pollywollydo]

So what’s the. Barge voltage and rate for this pack ? Just getting started🥴

[quilvinlowelcastillo]

sie ilang ah po ang total niyan? at paano po makuha ang ah ?

[GuestTwentyfour]

What heat do u use on the soldier iron

[abirpranto-hu]

With this current wait 20 year to full charge 🌝

Sir 18650 Lithium ion battery ka life style Kitna Hai.???

[genmckoy]

Boss how much po safe discharge voltage ng 18650 battery pack? Bumibili lang ako kasi hindi ko pa kaya mag build. Sana mapansin.

[jonathancharlesferriols]

is that a 3s 60amps bms? or if hindi pwede bang ganitin ang 60amps?

Ilan oras 12voltts 20watts bulb 3s7p magdamag ba ilaw? Sana masagot mo dalawa ko tanong. Godbless u❤❤

[juangonzalez-zvpj]

Cuantos anperio hora tiene la batería

[ramiesarsalejo]

Boss tanong Lang ako Kaya ba mag charge maghapon 3s7p na 20watts solar panel pwm kulay green

Merhaba. Bu aküyü nasıl bir devre ile şarj ediyorsunuz?

[claudiuserprinse]

Hi, I would like to make a battery pack for UPS with 18650 3000mah BMS 60A 3S 6P batteries, what do you think?

[laurabarnes]

Can I parelle 2 of this pack to increase the total amperage
