Top speed ?

Hello dear sir it's me Norman Wray wants to buy a 24 voltage lithium iron battery from you so get my name as your customers ok thanks 😊😊😅

Why did the battery back have green and blue cells?

You need security Torx heads to remove the screws. To release the two little covers for the screws, a good idea to lift up with a chisel from below. I cant see any way to remove these without some damage.

injineer you have done will we love you.

Hi. Is there a way to "unblock" a blocked BMS on Shimano Steps, or will replacing the dead cells with new ones reactivate the BMS? I'm interested in repairing the battery for a Shimano Steps BT-E6010. Thanks!

keeping silent all the way is the way to explain things!

10Ah 🤔 what type of 18650 did you used?

24v 250w electric cycle range kya hogi battery se?

24v 250w e cycle kitne km chalega isse?

Ти жену свою берешь тоже в рукавицах?

so when i charge how the batteries gain more weight ?

Thanks for this. Mine needed a head repair and other videos were showing a different model. It seems like Philips are pretty intent on making the insides of their toothbrushes harder to access and repair.

I had a very unpleasant experience. A client of mine, brought the functional battery and I in my tests I endeavored the battery! My tests consisted of checking the full capacity of the pack before balanced, which in the case measured 10.6Ah and how much capacity would have after the active balance. In the case measured 12.5Ah after the test. The stress range, from 2.5 to 4.2V by cell. Never do this with BMS on, to do this test I should have removed BMS like Mcellbatteris said! Anyway ... living and learning. Congratulations on your video, very good!

Is it possible to buy the laser cut nickel sheets somewhere? Or are you planning to sell it?

hello, I knew that these bms block if you take off the cells! how to do it right ? Thanks

"Promosm"

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.

Hi, I have a problem with my V60 MY 2020 plugin hybrid. The battery do not charching and turtle appears while driving, reducing power and switch out the EV battery. I'm waiting for maintenance now, diagnostic result are shown the foult code: Hybrid/EV battery cell balancing circuit E range/performance.

Hi, great video. i enjoyed it immensely. I have a Volvo XC90 T8 2017 model with the 10.4kw/h battery and i would like to replace it with the 2021/22 18.4kw/h battery removed from a salvage car. Is this possible? And if yes can the electric motor also be upgraded with the new 2021/22 one?

looks very commercial. two tips. bigger heat gun. dont cross bms sensor wires. if they short to each other or get pinched = fire

Thanks for sharing.

nice video

Can you make one 24 v 4amp or a 36v 4aml out put or tell me what to use

bro, you could make it 10s6p for more capacity

24 or 28 volts? 7SP3?

Hello, I assembled the same battery, tell me to charge it only at least 5A charging?

How did you get that thing out of the car ?

Pouch cells should no longer be used. They are cheaper to manufacturer but have consequences as shown in this video.

Super!!😮🤌🏻🔥 good job

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.

Nice job, but I’ve watched loads of these now and nobody says a word. A bit of explanation would be very helpful you know.

Thank you

Pls can you tell me the tools used to make the battery. Thank you

Where can I find those cell holders and nickel strips?

What is the diameter of the hot shrink pvc?

Di solito nn vanno saldati prima i paralleli?

This is just a seven cell, 24v battery, butt three wide, yeah? Off of the same bms. I was unaware you could do that. Excellent. I need some fat-assed batteries for the boy's electric scooter. Thank you random stranger!

nice

When I press the button first, show up immediately the 3 orange lights, and then 1 red light. What is the main problem? The PCB or the vacuum motor?

I must have done something wrong. The machine starts only while charging and then wont stop until not being charged anymore. Anyone have a solution for this?

There’s gotta be an easier way!! I’d like to build but Damn that’s not a quick process

Next time, build a rig for the soldering job. holding the T-Connectors is better as soldering them on the table - thats not a good solder job here. dont do this like shown here ^^

Now the shit won't do nothing on a charger + when on a charger and I press and hold power it glows red Nothing is overheating

👌 perfect

A physical barrier more than kapton tape would be preferred for the BMS/balance cables. Something like barley paper but this is a really minor thing to point out. The fact that you're using kapton paper is enough honestly, TH-cam is full of Indian kids using cells that look like they died 10 years ago and have been rusting away at the bottom of a river ever since, put together with zero capacity, IR testing, no balancing is done prior to assembly they don't even look at cell voltages and then they solder some random wire to the terminals and call it a day. Followed by 1200 comments saying "Genius boss you are great. I wish one day to build battery like you" Ehhh 20 seconds later the barley paper comes out! This is a quality build, just don't use the Smart Daly BMS's. The dumb ones are just fine though, good price and they work.

What is the charger boltage? I lost mine and used an 8.4v but got damaged

اشكرك can you show DIAGRAM please?

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

Gostei muito
