Good stuff bro glad to see everything is solid …
so this is what brimstone can do, if anyone wants we could do a group buy.
Nice!! Glad that is working out.
Keeps us in the loop hammer 
wow cant believe i made my last post but forgot the pic
this is what they can make me with their printer, its not as many cell as i want but it will cut me down to 5 pieces instead of 20.
if anyone wants any for their own pack i could talk with the guy.

3D printing is expensive for big pieces. I have a sled for 24 cells that I put together out of 3D prints and then made a mold and now I can pour whatever resin. If any of u want one pm me and I’ll pour u one for the cost of the rubber. Maybe 20$ for 90 duro rubber or I could do a hard plastic. It adds compression and also flexes a bit with the board. I’ll post up a pic later today.

I’ve made a bunch out of differnet materials. I need two but can’t decide which would be best to use. I plan to make all the connections with just the copper pressed and then sink the cells in probably a clear rubber. It’ll end up a long solid brick with two wires coming out.

so fuck ton of ride time now.
pack still works and works great for the most part.
the problems i have had though include -lots of rattle from the case at speed on 83mm wheels, fixed by going back to 90mm. -my solder joints sucked at first so i have to check cell voltage in trouble spots so i dont run them in to thermal runaway.
but the pros outweigh the cons -bad cells can be removed and replaced in 60 seconds if i have a replacement. -due to the current rating of the the contacts if i over draw (I.E short) it will blow like a fuse and save a cell or two. -fault finding is a lot cheaper since i dont need to slice open a heatsrink wrapper. -it offers the safest most balanced charge possible because i take each cell out one by one and charge it on my 4 bay and 6 bay charger.
like this set up is great and offers so much there are improvement i can make and will make on my new build but for now its perfect.

How much would he charge for 6 packs of those? I’m wanting to build atleast a 20aH 6s out of 18650s
@delta_19 NIce work, dude!! I don’t suppose there are any pics floating around? I’m glad this works out! It really makes the concept of DIY battery maintenance super user friendly.
for my custom sleds (4 2s4p and 2 4p) it cost $68 usd in total but, the 4p sleds where 6.50 each and 8 cell bays where 13 each.
@Ulfberht there are some pics in the thread but i can take more
Cool man! I’m totally inspired by your build. It’s a little pricey for those sleds, but it sounds like the tradeoff could be pretty freakin’ sweet. You could swap out to a totally different battery type, chemistry, or whatever without changing a thing. Too Cool! I soooooo want to try this out.
Yeah def sounds really pricey but does save alot of soldering and worryin about burning a hole and lighting your li-ion on fire 
would be cool if someone started a product line of 6-10s ready sleds at a better cost ratio for the DIY battery guys like us
Where are those sleds from? Are they custom made or are they online somewhere for sale?
Thanks for replying in the thread.

EDIT: The sleds are 3d printed. Something like above.
I got mine from brimstonevapeco.com $70 all said and done. They are custom just email with what you want

How are the sleds doing?! I really like the freedom from soldering or spot welding but worried about the vibrations of my stiff board breaking connections.
What’s the electrical resistance compared to soldering or spot welding? I’ve heard the best connections with the least resistance can be achieved with compression. The solder tabs can’t be made of copper because it’s too conductive and wont build the heat needed to melt it with a spot welder.
i have had a few breaks but only with lead based solder silver is stronger.
im not on the forums much right now because pokemon go is a thing.
