I have created a 7s 15 p battery pack with bms, and tried to use it with apc ups.. It just trips when power goes.. When i use it with existing battery in parallel it works fine

[@mcells_batteries]

Hi, voltage is same? 7S has 29.4Vmax, try discharge battery to 24V and try use it in ups.

[@carlosguzman4461]

Check bms limits

[@antoniovescovi2351]

sorry but can't you explain what those black battery holders and the various stickers you stuck are? And then there would also be that circuit board you plugged in later. Can you put the links where you found the various materials and tools you used to assemble the battery pack? Thank you

[@cikokustamsi1453]

[@hollywoodj500]

Holla budy can you please tell us what kind of Spot Welder you were using in this project please?

[@DroneSurf]

My only suggestion will be to add the gasket insulator same you use on the side of the battery on the top and bottom or fiber glass insulators. Other than that looks amazing.

[@mcells_batteries]

Thanks for comment. Yep, today we use fishpaper for all sides, battery pack is wraped to shrinkable foil like in video but on sides we use insulator glue for waterproof efect.

[@GregOnSummit]

Where did you get the wire stripper?

[@bryancunningham1095]

Great video, that very first weld on your first spot didnt look like that first weld took, i only see one dimple on your closeup, rest look fine.

[@mcells_batteries]

Yes, sometimes is welding pressure little bit different and it make some changes but it has not effect for final work.

Hello, May I ask which cable cross-section? you used ? Thanks in advance.

Will it matter if I get a 15amp bms for this battery pack?

Very very nice pack and craftsmanship but the sound of your tools smashing the table was Killing me....

[@mcells_batteries]

Get lower volume :D

[@thompsonibeh344]

How much does it cost for a setup like this?

[@KetansaCreatesArt]

Great job. Worked systematically. They say if you cut the balance leads unevenly short and long, there will be difference in resistance and the cells will be charged unevenly. Is it valid?

[@divikumar5475]

Its a small pack its ain't gonna get a potential difference between the balance leads

Hi, can anyone tell me what is the white striped wtape tht was used to hold down the BMS called? Thanks in advance! Appreciate it.

It’s a certain kind of packaging tape that has “strands” in it to give more rigidity. For the life of me I can’t remember the name.

Hi Thanks for the video very helpful. My first attempt at making battery pack for EBike, only able to get 18650 2200MAH cells, will they be ok to use?

Brother Nice demonstration and excellent clean work. I just have one doubt.. why did you use a black wire for battery and charge positive ? and why a blue wire for battery negative ?

[@bilalswed7522]

How can I assemble batteries with a capacity of 24 and a current of 150

[@bobforte9343]

Capacity of 24Ah? You’ll need a (insert number for voltage) S and 10P pack if using 2400mAh cells. (Insert)S5P if using 4800mAh 21700 cells. 3000mAh cells would be (insert)S8P. The first number I’m omitting is the cells in series. 7S for a high 24V. 6S for a very low 24V. 4S for a 12-16.8V and 3S for 9-12.6V. Thankfully 36V fits just about perfectly at 10S with 3.6 nominal and is close enough for 3.7 nominal cells.

[@arnoldluna9513]

How's the temp.cut off with the red cells?

[@mcells_batteries]

Inside of pack is bimetal switch with cut off temp. 70°C. This protect pack from high temp.

[@kwicwrk169]

Surprised you soldered them ends n not taped them like everything else 😂

[@mischamick]

Nice build, very clean, thumbs up! But 2 comments from my side: -At 5:10: Too dangerous in my opinion: While welding on the second side of the battery, there should be some tape for isolation on every cell you are not working on at that specific moment. If you missplace your strips left or right or one strip falls down on the pack while handling it or something like that you´ll get a short. Also if there is a metal strip or anything else conductive left getting under the pack. -Why are you using black for the positive discharge wire???

[@mcells_batteries]

Hi, thanks 🙂 1. - Yes, I realize it but I know what I'm doing. Therefore, I often check the location of the connectors. 2. - I ran out of red wires 😁😁

[@theo2378]

Ran out red wire lol

[@m.barrios]

Hi! the video is superb. I would like to ask you why you use a 7s configuration instead of 6s? which do you recommend and why?

[@mcells_batteries]

Hi, thanks :D 7s was better for customer device, has higher voltage, higher energy instead of 6s.

[@m.barrios]

@@mcells_batteries thanks for the fast replay. If my device has a nominal voltage of 24V VDC, would a 7S configuration be suitable or 6S is more recommended?

[@mcells_batteries]

@@m.barrios You need know maximum possible voltage, but if is 24VDC nominal voltage i think you can use 7s.

@@mcells_batteries thanks so much for you support! Continue the good work 😃
