I want to build my own battery, with a specific geometry (quasi triangular, to fit inside a standard bike frame) and capacity & discharge rate requirements.
AFAIK, only em3ev "officially" builds quasi triangular batteries. I believe Schwibsi, a member here, can do that, too. But I want to build my own.
I have been asking around who could spot weld in Barcelona, but I cannot find anybody. Even, an organization devoted to e-vehicles, they have told me this is a recurrent issue, but nobody really knows how to do it.
A member of this forum, cwah, kindly suggested he could maybe do that. Definitely I want to explore how this could go. But I have found another way:
supowerbattery111 sells packages of cells already spot-welded, either in series on in parallel. For example, if I wanted a 10s5p of these nice Sony VTC5, I could ask "brics" in 10s or 5p, I have been told. Then, connecting these brics is to be done with soldering, not spot welding, which I assume I could get it done locally.

Question:
The "normal" thing would be to have 10 brics of 5p, in order to connect them in series to build a 10s5p, right? It would be as if I had 10 cells, and each cell would be connected in series, and also connected to the BMS. Is that right?
