NESE, the no solder 18650 battery system

Should you use button top or flat top calls with the NESE?
Also, has anyone come up with a good design to top mount the pack on a mountain board? I know you can use somthing like a pelican case but I think they just look meh.

Flat. And yeah, I have seen NESE builds mounted on top. There is a NESE build thread. Look for that…

I have 1 new unused diebiems. Bought it for dimensions only.

I have seen 3d printed topmount cases for nese.

Impressive! :clap:t2:

You found a very good solution for some problems - good job :+1:t2:

I’m trying to price out some stuff but everything has just 1 in stock.

How much would a complete 13s5p 21700 set cost me? Would be in a brick configuration with your series connection tabs.

TIA!

I’ll take it…

I am sold out and everything 3d printed is on backorder with min 2 week que.
You can still order what you need and take advantage of the discount, i will still apply it if the time runs out as you inquired before 15th.
The cost including shipping could be calculated on site. You need 13 x 5P modules and 12 bus bars

I got some Samsung 50G cells with no shrink wrap. I’m thinking of using them in NESE without the shrink wrap. I would just add the insulation ring.

Is that a bad idea?

I’m a little concerned about putting the cells in the module and removing them out. The insulation rings tend to slide off and if that happens the cell could easily short out at the positive end. Once they are all in safely, I don’t think there’s any potential issue.

I have done it. But just on one module. I would insert some fishpaper, seat the cells then pull it out.
Risk free :slight_smile:

So, after more thinking… isn’t this a one way ticket though? Because I can’t really think of any similar trick for getting the cells out safely.

I guess I’ll just use the insulation rings and do the installation outdoors… and keep my fire blanket around… you know, just in case.

I would try and print single layer, prob 15mm wide blade and stick it in between when pulling out. Or search arround for tough thin plastic to use for separation of contact. I think its safer pulling out than putting in

Greetings @mishrasubhransu, I really like your latest design for the NESE mounts! Do you have enough on-hand to sell me what I need to mount 12, 21700 5P Modules? This Switchblade is still setup for pushing with the tiny wheels, but I am thinking about swapping on a set of direct drives to have an efficient street board with 20AH of range.

On a related note: have you experimented with any sort of skid plate to protect the NESE enclosures from potential road rash or unavoidable puddles? I am thinking about cutting down a sheet of Lexan to the shape of the assembled pack or I may try my hand with heated Kydex to get a more contoured fit.

Yes, I made a few extra sets. Made sure that it works with 21700 modules too. PM me for details.

As for skid plate, I have used acrylic plate in the past, but in newer board I prefer to have a ABS vacuum formed enclosure.

I didn’t order enough bus bars. Does anyone in the U.S have about 5 they want to get rid of?

If you wont find any, give me a shout, i can arrange them with cheaper, untracked shipping unless you are tight on time

cool…I’m good on time. If I don’t find any…I’ll let you know. thx.

having some sort of open source 3D printed NESE version of this design for the community would be incredible … but is it even possible? - a question to the dudes that make a these things @mishrasubhransu and @Agniusm (And I dont mean with the Trampa PCB/Circuit board…thats too complicated, just a regular NESE in this config)

Sorry but design of what? Integrated plug and play BMS with couple xt connectors? Cause by the looks of the dimensions 12 x 7p nese would come out same or smaller, even adding one nese enclosure for bms.
On the other hand its very limited and only few people would benefit.
I think its too complex. If bms goes, everyng goes or at least you would need to reasemble everything with premium on the bms/cell board. Rather than swapping off the shelve component.
I am against designs that are complex. I see many on fb battery groups and they are always left in cgi state

Sorry, no I didn’t mean integrated plug and play BMS, just mean a single 3d printed NESE pack design like you can see better here

But what your saying is this is basically already possible with the existing designs (you would just have to stack a number of the NESE units horizontally) and that the same 12s7p NESE would take up even less space than this Trampa one?
