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.
042723/0543h PST 🇺🇸 TEST-1 Thank you for pointing out the flaws in the assembly. I was like aghast when the spot welding was performed, quite unusually. Also, it’d have been quite appropriate if an insulating sheet was spread at the bottom of the cell array and specially on the top. When the lid with both terminals were being placed, I was in shock. Aw well…
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 ?
Yes, i was doing it no problem. I am courius is this possible to connect in series to get higher voltage but i am not sure and i dont want to damage the bmss
Thank you for showing the polarity and current flow

Do I need bms wen I already have Mppt charger and can I parelle to set of a pack of 12v 60000mah

Can you explain what the purpose is?
Hello. where did you buy the cells, and how much did they cost? thank you in advance
What is the capacity of each battery and how many amperes is the final power?
Абсолютен аматьор!
hello, i am a beginner want to ask, in your video is a 3s 7p circuit. what if i want to make 3S 2P with 18 batteries? thanks for your answer
How 3s2p with 18 batt? 3s2p is 6batt
sana lagay din sa description yung mga pyesa paps. pra may guide kami
So what’s the. Barge voltage and rate for this pack ? Just getting started🥴
What heat do u use on the soldier iron
मुझे चाहिए एक पैक कितना प्राइस है इसका
Hello there

Anything that can done about that ?
Price
is that a 3s 60amps bms? or if hindi pwede bang ganitin ang 60amps?
Power Bank se spot welding kaise iska ek video banao na sir ji
Sir spot welding machine ka video banaiye sir ji..... Plzzzzz
Cuantos anperio hora tiene la batería
Hi, I would like to make a battery pack for UPS with 18650 3000mah BMS 60A 3S 6P batteries, what do you think?
Thats ok if its 12v appliances because if you use like a 24v battery into 12v appliances like wifi routers it will fry the board
Sir 18650 Lithium ion battery ka life style Kitna Hai.??? .....
Up to 2 to 3 years i used brand new battery 2500mah each cell
Can I parelle 2 of this pack to increase the total amperage
Yes, i was doing it no problem. I am courius is this possible to connect in series to get higher voltage but i am not sure and i dont want to damage the bmss
How much demo
sie ilang ah po ang total niyan? at paano po makuha ang ah ?
Boss tanong Lang ako Kaya ba mag charge maghapon 3s7p na 20watts solar panel pwm kulay green
How much ah
Merhaba. Bu aküyü nasıl bir devre ile şarj ediyorsunuz?
Bms 3s40a
@helectro3021 bms değil. Şarj aletini sordum?
Boss how much po safe discharge voltage ng 18650 battery pack? Bumibili lang ako kasi hindi ko pa kaya mag build. Sana mapansin.
With this current wait 20 year to full charge 🌝
Ilan oras 12voltts 20watts bulb 3s7p magdamag ba ilaw? Sana masagot mo dalawa ko tanong. Godbless u❤❤
Boss ask ko lang Kong pwede ba magkaiba Ng mah pero same voltage lang.
Dapat po hindi nag kakalayo ng capacity .
Какая толщина ленты? Чистый никель или нет? Какую устанавливаете мощность для сварки?
hellow sir what kind of bms is that? can you give me a link or name of that bms? thank you sir
3s Bms 25a
shp.ee/y7ks5tg
Or you can purchase bms only from this shop
@@edisontechvlogs8766 thank you sir
3s 12p 30 amps na bms ok rin ba?
Boss ask ko lang pwede bang magkaiba ng mah pero same voltage lang Yung batt.sana masagot mo Ako boss..rhanks
Mas mainam po hindi nagkakalayo ng capacity ang battery
Salamat boss ha..ok lang sya 1500mah to 1590mah?
How much money 💰💰
I'll pay
Please send
❤
Ok pero dímelo potencia del soldador y ce celdas
Soldering iron 60w
2500mah each cell
How are you charging your battery pack?
You can charge it on solar or you can just plug in your power outlet by using ac to dc charger
what volts and amp does the charger need to be or have you got a link were i can buy one @@edisontechvlogs8766
spot welding hot fingers??? at 99%
For 2 dollars more you got a 100 amp bms
It would be around 15 ampers per cell. The question is: isnt it too much for one cell ?
