That’s awesome, thanks M.Hboards! Where does one get the PCB’s from, Google ain’t helping me find a store. Interested in seeing what braid you guys are using too. Brilliant stuff, tidy, my OCD is at peace looking at this eSK8 porn!
@thisguyhere sells the pcb and nickle (and braid if you ask) that’s where i got mine from. However you could get everything from China ( even the pcbs which are open source thanks to @akhlut) if your not in a rush but in my case i really wanted to finish my build quick so i ordered my pcbs, nickel and braid from @thisguyhere.

Didn’t see your response, but it looks like mhboards hooked you up with the info!
Just finished my battery swap for the GTX. Gotta reassemble but that the easy and fun part, haha.

Sorted everything I think JD, except the PCB’s. I see Esk8 life sells the 3p and 5p alternatives, but not the 4p 
That BMS wiring (yellow) is nothing short of art dude!

Thanks.
So another place that sells the boards (but everything included in the kit including sized nickel strips) is kaly.nyc. A little pricey but it is a complete kit to build batteries. Check them out as well
Tried getting the boards from the same supplier thisguyhere uses, but the robot came back with this message when I uploaded the Gerber file:
I’m going to try to get them to FIX it manually as I’ve no idea how to edit the gerber file.
I used to have a CNC machine that I milled PCB with, wish I’d kept it now!

Boards ordered, Peter Pan (actual name) will send me the updated gerber file when it’s done so I can share it for next time!

Thanks man, but just to be sure before I overcharge C7. The board charges through the bms wires, not just measuring through them? Why can’t it balance automatically then? I thought it charged through the main pos/negative and only used the bms wires to stop charging when any pack reached 4.2v (In this case C7)
because once one pack reaches 4.2 the charging is stopped… which is why you have to do them in groups.
I only just noticed your cunning battery layout! Instead of the LHB layout, you’re running your series links along five packs, then up one, and back again. So no massively long positive feed. Genius! Wondering though, it’d be way faster to weld one 30mm wide strip of nickel along the top and bottom of each pack, bent over and tacked onto the PCB than having to cut 80 pieces of 8mm wide strip eh? Any disadvantages you think?

You talking about useing the type of Nickel in the pic below? If yes I don’t see any reason why it wouldn’t work.

Hey dude, I just happen to have bought ten extra ! I’ll send them your way if you send them back when you do another order/ stock up? [email protected]
Thanks for the offer, I think* thisguyhere has a few in stock so I can go that route. But, I appreciate the offer!

That is beautiful!
Does it fit the GTX enclosure without any modification?
Thanks. But no, not entirely. 10S4P is too long so you have to stack the BMS on top of the esc. To do that you have to route out a pocket in the wood so it’ll fit.
Hey JD, I’ve got my nickel, and I’ve started tacking up the packs using 80 current, and 2 pulses on my Sunkko 788H, but when I tack onto the PCB it blows a small hole through the nickel and I can smell it’s burnt. Do you wind the current back for tacking the Nickel onto the PCB mate? Thanks in advance…
