Module is at least 3x more expensive than 18650 cells itself 
No thanks, i stick it with hot glue.

Yea, looked cool until I saw the price. Even for bulk quantities, we are talking $22 per 8 cells and thats not including connecting pieces. So basically the same cost as bulk 18650 costs... It would be a nice product at about 1/2 or 1/4 as much $.

At least we got some idea to build something similiar itself. :wink:

8P modules...interesting. Could be configured in a flat plane or in a cube. I think in this day of 3D printing, it would be very easy to copy, so...I am a little surprised that the price is so dear...
i think it's because they brag on having it been made in France.
i too think it is way too expensive.
Now the important thing is the plastic used what i have read is that it will no burn up and go into flames , they mixed a fire extinguishing product with the plastic and it''s tough enough to be thrown on the ground several time from 2 meters height without breaking with cells inside.

Prices are high in the EU for anything on an ebike.

It really does seem to be a well thought out design.
But that price is just too high.
Yes it's servicable, but for the extra investment you could just buy another pack with brand new cells rather than trying to service a pack of used cells.
I wonder how it would handle extremely high current draw after long term rough use?

It is very interesting design.
The air cooling and flexibility is key. Very impressive. The fact that they built fire proofing into the plastic is smart.
I found another serviceable battery for golf carts years ago.
I lost the graphic - no spot welding - however it was bulky heavier and inferior to this design.
These kind of posts interest me allot. The use in aircraft - thats amazing -
It got me thinking about whats inside solar impulse - and its modular battery?
It must be an incredible piece of engineering.

Hi there,
Here is a new technology that just came out for any interested person that want a very easy way to custom build a battery pack...
You can use many cell chemistry for the 18650 form factor,
no need for soldering nor spot welding,
assemble like LEGO blocks (serial or parallel)
optional BMS available which use cell phone (or portable media compatible) as display via wireless.
This is simply amazing!... TYVA ENERGIE....

WOW. that's expensive. I can't see the value in this unless the price goes down.

spring contacts. cell density. yuck.
If tesla used these they'd be selling a P65D instead of a P100D lol. And it would be 300hp instead of 650hp due to the spring contacts.

This is what it actually is:
I wander if the holder has some sort of stop so cell weight does not lay on the springs. Ether way dos not look like reliabe solution to me.
2s8p 140€ plut vat without cells.

3d print versions of it will be possible sooner or later- keep checking on thingiverse. But i dont see a use for anything besides hobby and maybe testing. Manufacturers dont want consumer to be able to diagnose to swap out a dead cell, they want to be able to sell a whole new pack. This product wont go far in real life EV world imo.

I had a similar idea except with 13 cell in each module :

250 euros for 4 empty units (sold as starter kit)... So an empty 32 cell battery box for 250 euros.... Way to expensive
The springsteel contacts they use also seems like they will not be able to hande anything much more than an amp per cell...
The thing is, flimsy spring contacts creates resistance.
The added resistance generates lots of heat when the amp load is high.
Heat is the worst enemy of springsteel, as the tempered metal looses it's recoil past a certain temperature.
So the springs really need to be made of a beef wire gauge to withstand the amps without too much resistance.
Steel is also not as conductive as copper.
But copper does not have good recoil, and copper will form surface oxidation over time and create additionnal resistance.
I'm thinking they should invent springs with a springsteel core coated with an ultra thick copper-layer, plated with nickel for oxidation resistance...

Here are the internal cells configurations...
You can have 1P, 2P and 8P cells arrangement accordingly to the top and bottom lids version used.
See enclosed assembly manual...
