 the production cost of the BMS is almost exactly 140 euros, quantity of 25 boards produced in Germany locally. Would estimate if you find some cheaper components, for example, the terminals were quite expensive, like three euros something per terminal. And yeah, if you have an integrated solution where, for example, you already know that the cables are going here or there, then you could easily change the BMS design a little bit and maybe solder the wires directly onto the board or have another solution for the terminals and save a lot of cost. And also for a larger quantity, obviously, cost would go down. So I would estimate can go down to 50 euros, depending a little bit on the really the current you need. But yeah, that's the ballpark numbers. In terms of competitor BMS is so what I've seen on the market, usually around 400 to 500 euros for BMS systems that are comparable to this one. And yeah, obviously, they need to put some margin on their production costs. But if you need a BMS inside your battery system, and this BMS suits your needs, then you could just go ahead and let it be produced for the much lower cost than if you buy an off the shelf one.
