As of now, It will take me a day to print a set of 12s4p . That’s no where close to being sustainable. Because I will still be printing these I’m doing an early cost ended up higher than I wanted to be.
You will have the option of mix of 1s4p and 2s4p modules for cutomized flexibility at different part of your board. Pieces will be cleaned up, Inspected and test fitted before shipping out.
Dimension of 1s4p module is 22h x 73w x 76l 2s4p saves 1mm in length.
- 1,2,3,4s 2-8p modules
- Stagger stack
- Align stack All available as long as it doesn’t exceed 10 cells in length. Price will be figured out and discussed.
- Choices of 30Qs or VTC6
- Hex bit to save elbow grease
- Mini hex bit ratchet (highly recommending hand turning for finish compression. Not liable for damages caused by over compression)
Offer will be availabled once beta tester receive their units within 2 weeks and provide user feedback and pics.
Saving you some math and comparison:
NESE 10s4p modules = 90 EURO (with 4p modules) and 84 EURO (with 2s4p). + Shipping
Warnning! Subjective opinion, Do NOT over react.
Advantages over spot welding:
- Low initial cost
- -cost on spot welder
- Save you time and effort to
- Research spot welding technique
- Source material
- Easy to replace cells
- Easy to upgrade battery pack
- (Work in progress) travel friendly. Dis assemble into smaller packs for flights
- Lesser conductivity between cell and busbar/braid contact (this is debatable, not going to argue.)
- Not fool proof. If you assemble wrong, you and I will be very very sad.
- Material, 3d printed part not the best at mechanical properties. That’s why I’m raising money to scale up production using other manufacturing method.
Advantage over NESE:
- shorter module length across cell diameter for more compactness
- Adjustable flexibility between modules
- Future prove as I will keep working on these and backward compactible is on the list.
Disadvantage vs NESE:
- Require a little longer and more tedious to assemble
- can mess up you if assembled incorrectly
