Pretty good looking pack, nice job.

Is that 25 or 30mm nickel?

Lol, didnt get pumps, saved 30$. Gonna mix by weight and use large syringe for transfer.
Gonna be fun learning in the shop when rest of materials come in.

@Halbj613 You’re faster with a with a file. Just deburr the edges and wipe each edge on both sides only once and you’re done.

outline is @BillGordon

Halbj613 · January 17, 2021, 10:58am

long past that stage but good info for next time

building a battery is way more work then i expected

probably put 10 hours+ into it now

cfelzien · January 17, 2021, 10:59am

Holy fuck how big is it? 30s400p?

Mainflow · January 17, 2021, 11:00am

Oh and you’re left with sharp again

Movation · January 17, 2021, 11:02am

I can take that long, I will often take a whole weekend to build or rebuild a battery, I Ballance test my P groups before final assembly. Anyone who tells you it’s cheaper to build yourself is on drugs especially if you value your time.next time I will send my cells to @TinnieSinker to build. It will be better built and my wife won’t break my balls for being in the shed all weekend.

I’m just fucking with you. I know a good pack takes time. That’s why I use makita batteries.

Halbj613 · January 17, 2021, 11:07am

cutting nickel + rounding
welding
fishpaper
soldering
balance leads
making sure evrything is good
protecting pack

cfelzien · January 17, 2021, 11:10am

I tig torch all my packs. Use foil to connect p-packs. And use a small food scale for balance.

Halbj613 · January 17, 2021, 11:10am

15 minutes and done

cfelzien · January 17, 2021, 11:11am

Fucking send it. I ain’t got time for perfect.

Movation · January 17, 2021, 11:16am

Last time I used the derelict robot battery PCB and that was my quickest build ever around 4 hours. My cost was around $500USD for a 12S4P pack. I spent a shit ton on 50mm 0.2 Nickel (1kg) before realising I could have bought it from Andrew pre cut for the pcb for a just few bucks. ::facepalm::

itsmeOli · January 17, 2021, 11:29am

thank you, its 30mm x 0.2mm and i welded at 35-45J

BillGordon · January 17, 2021, 11:41am

Me and @Linny will be building a pair of these @DRI PCB batteries out before summer. We’ll be holding hands the whole time.

glyphiks · January 17, 2021, 11:44am

If you need to offload some of that nickel…

Movation · January 17, 2021, 11:44am

It’s so easy if I had bought the precut nickel it would have only taken an hour. No balance wires it’s built into the pcb.
