Building Solderless battery pack
#1
It has been a few month back since starting working on the concept of solderless solution. 
I need something that can build around bigger pack for high power application like powerwall. 
Tried many concept and fail due to adding too much stuff and weak structure. 
The final concept is very similar to everyone's build but with added panels on both sides.. with "Fuse"
It takes me literally months to come out the design and correct dimension to work with. 
"Fusing" is also not easy to come back even spending days doing research and finding suitable method to implement.
Overall I pleased with the result amid some minor improvement. 
I was surprise during the first prototype how fast the assembly takes when building a battery pack. Only ~15mins.
You may want check out my blog on this project.

Nicely done!

Your individual cell fuses are quite brilliant!

Yep, I search high and low to come out with this simple solution... Sometime simple thing is not easy.

Do you have an idea of what each kit will cost to purchase?

$155 for one? That means a 14s powerwall setup would cost $2170 in just holders. That's ridiculous...

For 14s is $140/pack. I understand from your point of view. This cost is pretty high at the moment due to the low quantity run as I want to test the market feedback. What's your acceptable range you're looking at...

If you can large bulk quantity battery holders, then something like 999$ for a 14S pack would be your best bet.
The power of lithium ion is in our hands!
We'll show them what we're made of!

Thanks for your feedback... 
I'm open to all feedback at this stage. Any feed back will take into consideration and look into. 
At the moment is a pilot run, we hope there'll be more people to support this project. 
With the pricing are more affordable, more people will get to build their battery power pack simpler and faster...

Yep.

Is there a way you could save on material costs?

What are the connections/busbars made of? Going from copper to aluminium would be good since it would be lighter, quite a bit cheaper, and you wouldn't lose much conductivity over a busbar.

Making a smaller pack of 32p cells would also be good for people on a tighter budget wanting to start.

Edit: Meant 32P.
