- Gather the necessary materials: You will need a soldering iron, solder, nikel strips, and 21700 cells.
Prepare the cells: align up the cells using a 3d printed plastic tab.
Connect the cells: weld the batteries with nickel strips or wires to connect the cells in series and parallel.
Wrap the pack: Wrap the pack with tape, neoprene, and heat shrink for protection.
Charge the pack: Charge the pack with a suitable charger and use it for your next FPV drone project.
This video will provide you with a step-by-step guide to building a 6s2p battery pack for your FPV drone. By the end of the video, you will have a better understanding of how to build a battery pack from scratch and be able to apply this knowledge to other projects as well.

Everything is very detailed! Thank you!
Just finished up the battery with new ones. Holly crap i got 13 miles on my 7" now
@@zoeconner11 are you on analog or digital system?
Thank you for the video. What are teh dimmensions of that shrink wrap you are using? please.
I used this this one

Am building a 6s5p pack and am confused at one thing, at +ve and -ve collectors can i use 0.15mm * 10mm pure nickel strip spot welded to 5 cells in the terminal group and solder a 10guage wire running the length of the terminal group on tip of nickel strip. Would this be enough to handel 100 amps continuous?
Well your video help me make my first pack. Just got the welder today. Not sure what i did wrong. About 2min in flight it drops to 3.2v quick. What did i do wrong? Everything charged up good. I checked when i landed it says 4.08v. So when do i land? Thanks
Did you use the same cells as I did?
It’s normal for it drop a bit due to amp pull.
Make sure to charge with Lipo settings and not lion, or batteries will not fully charge and drop real quick!
With lion you can go down to 3.0 with no issue

DJI O3?
What did you modify on that purple welder? Can you tell me, please? is it diode and something or ? tnx for help
I added 5 more mosfet and copper on top of the traces going from positive and negative to mosfets
@@GlishaSo I will take some pictures tomorrow and send it to you
@@Voodoo_Nation oke tnx!
@@GlishaSo Here is a video I uploaded that shows the traces, Mosfets are same as the orignal ones, you have to make sure you match the part number, I got mine from Aliexpress

What size heat shrink did you use?
I used this one
a.co/d/1TmF6nF
Whats a good amp to charge for these?
I charge it at 4amp
What's the C ratings
not sure on C rating but Molicel 45B can provide Continuous Discharge Rating (max) 45A (80C Temp cut-off)
10C
Hi what is the Mah of this battery pack and how did you determine it? I built the same with 21700 4800mah 6s2p
If you take two 6s1p 4500 mah batteries and wire them in parallel you will have twice the capacity (9000mah) but the same voltage (22.2 volts). If you wire the same two batteries in series, you will have twice the VOLTAGE (44.4 volts) but the same capacity (amperage), in effect it will then be a 12s 1p 4500 mah battery
Hi, I found your video to be the best that I have viewed. Thanks for the posting. I have a request for you to post the diagram you show in the video in PDF format so it can be printed and used as a guide.
I did make a diagram that’s in the video, I can make it a pdf if you like
That would be great. I photographed the screen of the diagram and it is a pain to use as a guide. Thank you.
@@benpowell3277 I’ll make a PDF and post the link
@@Voodoo_Nation Thank you I am looking forward to it.
See if you can download from this link
