Anyone have a source or sources that custom laser cuts nickel?
I’m doing a 20s1p Onewheel pint pack and i may be overly finicky here but really need this nickel design.
I know the single tabs mboards has something very similar so I’m not too worried about those but the two different types of series connections the field and the ends I can’t find something similar. Mboards has a 2s piece but the tab is ginormous most mine only need a small balance wire tab.
Also the end ones do you think putting that cut in them compromises the current handling in a significant enough degree?
Thanks guys.
Plan is to be 0.2 nickel and i like the slit personally to keep welds away from the center of the negative post.
Yeah i know i could probably hand cut them just prefer the cleanliness and consistency of machine made components.
Might have to bite the bullet a modify a printer with a laser head just haven’t done too much research on how beefy of a laser I would need to cut 0.2 nickel.
Yeah in order to eliminate 1 notch those would need to be 2 different pieces or put that balance tab in a weird spot on 1 side or the other. I’m not getting why they are too small overall. They are just about the same size of the terminals of a 21700 cell, about 12mm wide and 24mm long. Would it be beneficial to make them closer to the size of the hole cell? Kind of just matching what other precut nickle option seem to do.
You will need a fiber laser to cut through the nickel. I attempted 0.2 nickel on my 75w CO2 laser and no dice, hardly even made a mark on it. It’s too reflective of a surface.
Sweet thanks for the input, fiber is a but more serious idk if that’s easily retrofitted?? Or a good idea to have just out in the open… lol I got some research to do on that end… thank you!
I’m actually building a 20s1p 21700 pack right now. I’ve used zbattery solutions nickle for torquepack builds in the past.
Tonight I’m going to use doublestack 21700 .2 Amazon nickle. Just cut the tabs into the shape i want.
Yup definitely an option if possible though id just like them machine made I know it will cost more but how insanely clean it makes my batteries has got me hooked…. Lol
Yeah but man no way you are wiring it and probably no fish paper isolation either. I’ve never actyally stacked naked cells in the stock Xr box is the plus box really bigger??
I’ll post pics this eve. There is plenty of room above the cells for connectors and bms behind in the regular place. Plus box is definitely better for 20s1p 21700
Finally finished my v2 modular fly battery lol. Rode it today for probably about 30 miles (with charging) and it held up pretty well considering the small leads. Obv. it’s not meant for very high current.
The black stuff is not burning; I believe it’s just some grub that got into the case or just my fingers
Couldn’t find anything, you might need to open it up and look at the sticker on the pack. Seems from some of the blurry images to be a cheap brick type and no good specs. The sticker on the replacement batteries isn’t readable online but looks to have the information. My guess is it’s 30q type cells but no way to confirm charging current without opening it up. It should be on the sticker
There’s a local guy who has one of these. He runs 2x 4a chargers without issue.
If you really want, the battery bay is pretty easy to open and close up again, though if you want to retain waterproofing you’ll have to re-apply the gasketmaker compound (can be purchased in squeeze tubes)
When in doubt, charging at 1A per cell in a P-group is pretty safe, so if it’s a 6p battery then 6A should be fine, etc.
Good to know, that could potentially cut the time from ~11h towards 5-6h which would be plenty quick. It has 100-150km of range at my weight so no need for much more.
I’m very familiar to the concept (kinda built Lacroix Boards for a living ya know )
My problem lies with knowing the number of parallel without opening the floorboard.
I’ll probably end up opening it eventually but I would like to keep it closed a little longer before my ADHD diy brain kicks in and wants to modify stuff
I’m building this exact same pack right now as well. I was originally going to build a 15s2p and had these on hand.
