How to Build a 3s Li-ion Battery Pack

[@scottgivens27]

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!!!

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.

[@alirezabaniasad530]

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

Thank you for sharing this video. Thats exactly what i want to build for my 3" cinewhoops. Just for cruising and no crazy flying.

[@ciscocalderon5436]

That's great. Thanks for watching.

[@fishycomics]

Perfect video. thank you Exactly what I needed to do mine and the shape as well. time to order some balance leads ,

[@fishycomics]

update did one without a balnce lead , simply easy again thanks

[@harrisonbowie829]

thank you for the diagram.i looked and looked . yours made sense.

[@ciscocalderon5436]

Great! I was glad I was able to help you.

[@RoninFPV]

Nice job. Didn't know how to do this til now. Keep up the good work 👊

[@ciscocalderon5436]

Thanks for watching. You gotta just do it!

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!

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.

That marker sounds killing me

Try using hot glue to attach the batteries together on the outside of the battery case to secure them togerher.Then you can use shrink wrap or electrical tape.

@@RobertJarosz-en8qn I did this video a few years ago when I first started making battery packs. I just did an updated video with improved techniques. I posted just a few weeks ago.

[@tygerfpv]

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.

[@ciscocalderon5436]

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.

[@coverdestroyer3572]

your tutorial is easy to understand, because of the number mark, do you have how to 4s tutorial?

[@ronygarcia8079]

Thanks for the video!!!

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.

[@Eric_Tennant]

Side note I have made mistakes on batteries that can be viewed on my channel.

[@alirezabaniasad530]

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?

[@ciscocalderon5436]

I set it up like it's a Lipo battery. This way you charge the maximum 4.2 volts per cell

Ciao molto interessante il tuo canale complimenti 👍🔋😁🤝

[@timmytson1]

Nice job

[@ciscocalderon5436]

Thank you!!!

[@instantdough7220]

I buy a used driller battery and is the same also have some safety resistors or something elese

[@pcka12]

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!

[@gasisthepastendoil]

.... 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...

[@ciscocalderon5436]

@@gasisthepastendoil They have some battery spot welders in Amazon. Works great and super easy to use.

[@ericklein5097]

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

[@ciscocalderon5436]

I will have to try that out. Thank you.

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
