Hello Everyone!

This is my first battery build and I will upload pictures and some documents here. :slightly_smiling_face:

It’s only a post where I document how I build my battery.

Okay, let’s go build it​:slight_smile::raised_hand_with_fingers_splayed: Here you can find my ordered parts for the build:

-Spot welder: https://malectrics.eu/product/diy-arduino-battery-spot-welder-prebuilt-kit-v3

-Lipo battery for the spot welder: https://hobbyking.com/de_de/turnigy-battery-nano-tech-2700mah-3s-65-130c-lipo-pack-xt-60.html

-Samsung 30Q cells: https://www.nkon.nl/de/samsung-inr-18650-30q-3000mah.html

-10s Bms: https://bmsbattery.com/bmspcm/833-16889-smart-bms-10s13s-60a-with-blue-tooth-android-or-ios-app.html

We won’t lol. No, seriously. Ask before you do something if you are not 110% sure about it. It would be a tragedy to hear about another fire…

Better be safe than sorry

(I just mentioned the links to all of the parts which I’ll use👆.) Okay, my first step was a circuit diagram to see, how to connect each pack to the other one. I drew it with a pen on paper. :point_down:

Yeah, It’s for the first battery.

Don’t forget to make a salt water test with the nickel to be sure it’s pure nickel. Also would say that 3m is a bit less. How did you plan to install the nickel. Just on the plus/minus tap or single cell and bend over the edge?

Did you also get some fish paper to separate the packs from each other?

how many batteries are you going to be making?

I used about 11 meter for my 10s6p. 7 meters could probably had done it.

You can see the fish paper on the left side of the picture :raised_hand_with_fingers_splayed:

It’s for the taps…i don’t see anything which looks like a full sheet of fishpaper :tipping_hand_man:

Sound about the same i used on my last pack. But it sure also depends how you lay the nickel and how much layers you plan to add.

For sure I will build more then one battery. Because otherwise I wouldn’t had bought a spot welder. :slightly_smiling_face: And idk how much nickel I’ll need, but I’ll build 10 pieces of 3 parallel cells packs, so i only have to cut 20x 6cm strips.

So you add up the nickel with copper braid or silicon wire?

Yeah, with a silicon wire. So it will be a bit flexible.

Okay, sry for the bad picture :joy::raised_hand_with_fingers_splayed:

Not how you connected the p-packs, I mean to add up the one layer of nickel. One layer is not enough to handle all the current you could potentially draw with this battery pack.

I highly recommend you to read through this thread if you didn’t already made this.

I know, I read this tread. But thanks😉
