Thank you for teaching us "How to Build a 3s Li-ion Battery Pack". You made it so easy to understand. We all appreciate it very much. :)
You're welcome.
Finally I got the point . I've watched a couple of videos and articles , but I just understood the process know . Thank you so much
You're Welcome! Thank you for watching
What's up brother! I just made a 300mah 3s Li-ion pack using your tutorial! Still very relevant. Charging now and test flying my 3.5" Prototype in a bit. Thanks!!!
I have two power packs I ordered off of Ebay with four of these batteries. I got to power a headlight on my bike. They are covered with black plastic but they are the exact same color and size as these.
Thank you for sharing this video. Thats exactly what i want to build for my 3" cinewhoops. Just for cruising and no crazy flying.
That's great. Thanks for watching.
thank you for the diagram.i looked and looked . yours made sense.
Great! I was glad I was able to help you.
When I make packs, I use heat shrink tubing to secure them in and basically wrap them in. Tape works, but for a clean sweet look, the heat shrink tubing works well. just have to get some big enough! nice job tho!
Nice job. Didn't know how to do this til now. Keep up the good work 👊
Thanks for watching. You gotta just do it!
Thanks for the video!!!
Perfect video. thank you Exactly what I needed to do mine and the shape as well. time to order some balance leads ,
update did one without a balnce lead , simply easy again thanks
I buy a used driller battery and is the same also have some safety resistors or something elese
I don't trust myself to work with batteries, but cool to see how you can make use of these to make a bigger pack.
Thanks. it's not too difficult, you just have to take precautions. That's one reason I don't use flux because that could drip into the cell and that's not a good thing.
Nice job
Thank you!!!
your tutorial is easy to understand, because of the number mark, do you have how to 4s tutorial?
Thank you so much.I am just curious is there any way to charge this battery setting without parallel cabling ? And if there is , how should I set the charger?
I set it up like it's a Lipo battery. This way you charge the maximum 4.2 volts per cell
.... I used the battery welder from temu....then use some Car jumper cable clips And clamped it to an actual car battery and welded it up at 68%... No I'm working on some type of strain relief So the wires don't get jerked and I'm frustrated...5000 mah li ion very weak n heavy...
@@dnacannotchange They have some battery spot welders in Amazon. Works great and super easy to use.
You need a new felt time, or better a rollerball, cos i keep being distracted by wondering if it will work, or that squeaky noise!
Otherwise an excellent & helpful video!
Ciao molto interessante il tuo canale complimenti 👍🔋😁🤝
Best safe. On the top of each cell The negative is right next to the positive. Only a hair keeping them from shorting. solder could make a small bomb if it enters that hair crack.
Side note I have made mistakes on batteries that can be viewed on my channel.
That marker sounds killing me
nails on a chalk board
You are not supposed to put them closed to each order
....built e 3 cell 5,000 milliamp power Lithium.... Does it have any power and it only has a 900 milliamp power capacity.... Cycled it twice
There is no danger in using flux and compared to the amount of time you spent on the cell (4 seconds then 8 seconds straight on 1, 8 seconds on 2, 5 seconds on 3 and about 5-8 seconds attaching the wire. Roughly same amount of time on the other side. So each cell gets almost half a minute of an 860 degree iron) it is way way safer to use flux. With flux you can be on and off in less than two seconds with the proper tip per attachment per side so less than 10 on each cell.
Edit: plus balance lead time puts them at more than 30 seconds.
Edit edit: Kapton tape will change your life but its not super cheap. I got 4 different sized rolls 1/4" width up to 2" width for $11
I will have to try that out. Thank you.
