I ordered two different types of flexible busbars in order to compare them. Flexibility comparison is done without measurements. Just by the feeling I got while flexing them. The two types of busbars that I've tested are on the image below. The first is the laminated one from Weber Power Tech. The second is the braided one from the Minerals Official Store.
And here are the results:
The most important aspect is axial flexibility. This is what the busbar should mitigate while cells are expanding and contracting. For me the winner is clear.
Docan also offers braided busbars. The price is even lower, but the middle part is not tinned according to the pictures. I'll be using these for my build due to the price difference.
And here are the results:
- Axial flexibility - the braided busbar is the winner. The laminated one requires a lot more force to change its length.
- Radial flexibility seems equal.
- Contact area - the braided one wins. The laminated one has an oval hole while the braided one has a round hole.
- Price - the braided one is cheaper.
