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

[@abdelbary8]

Lithium advantage in storage capacity. its important to concern to choose the right cells with specs like discharge rate and the real capacity based on your application

[@Sydney268]

Nice video, not sure what happened at the end, obviously you used 10a discharge wires for a 100a bms which was a bit silly, but what shorted out? Also you should have a probe each side of the slot in the nickel to spot weld - they are there to force the current through the battery(not just the nickel)

[@abdelbary8]

Me too not sure what’s happened 😅. Anyway, I used a low gauge cable and I replace it with better one in an enhancement video for the same project. Thanks for your feedback

[@enderq666]

What I can imagine is, he is holding that bzel with negative and positive terminals outside. negative terminal is already connected and is pointing downwards while he is trying to route cable through the positive terminal. I guess he touched with negative terminal a positively charged place on naked BMS.

[@enderq666]

or, the other way around. It is actually negative terminal he is connecting.

[@abdelbary8]

I guess so that’s what’s happened 😄 we must be careful when dealing with batteries

@@abdelbary8 true. Very nice video tho. I will use it to make my own battery to power up my sons e-quad. thanks!

Kalo perbandingan kuat aki apa batre yang ini

[@gorillamotors]

Will that 3S 40A board work with 21700, 26650, and 32650 batteries?

[@abdelbary8]

It will work as they are lithium ion batteries within the board max current

[@gorillamotors]

@@abdelbary8 That is what I thought. Thanks for confirming that.

Please give me a link for the charger

How to charge? What kind of charger to use? Please help

[@abdelbary8]

You can use either 12.6v adaptor or multi cell lithium 3s usb type c board

[@sonybravia1416]

!! А можно эту сборку использовать не в бесперебойнике а с инвертером, если понадобится?

[@abdelbary8]

As long the used cells discharge rate and capacity are capable for your application it will be suitable. Additionally to the used bms too

[@sonybravia1416]

@@abdelbary8 !!! Will it withstand a 220v 200w load? And how long?

[@abdelbary8]

Without knowing your cells capacity and discharge rate and the BMS used additionally to the inverter and how many hours your load required to work i cant answer you even 200w is considered as small amount

[@sonybravia1416]

@@abdelbary8 !!! Assembly - 21x18650-7A, BMS 25A. How long will it work at 220V 200W?

[@jdedad]

Can you fix my battery pack? I have a couple bad cells

[@abdelbary8]

Repairing lithium battery pack could be done by replacing the cells with new. There’s many tricks to refurbish/getting them alive back lithium cells but be careful as that’s risky

18650 5000mah batteries 😁😁 3S 7P with 100A BMS 😅😅 insulation paper on side🤣🤣. You did the all wrong things

[@abdelbary8]

I agree with you, insulation paper used to isolate the nickel strips, Thanks for correcting me. Batteries and bms both are Chinese and need to do test on your own as I mentioned in the video. Anyway it’s working and FYI this battery around 1600mah only 😄
