I've found a picture of a BMS someone took appart.

The left one is from a Chinese copy but the right one is the original LG one. Looks like both cells would connect to it. Comments say that the original BMS has a temperature sensor and charging control and that's why some Chinese copies won't get recognized by the Surface.

I think I'm getting somewhere with my idea.

If it's done properly, I don't see why not. The only thing that might get in the way will be if there's an individual bms system in each cell that handshakes with the "central" system. I haven't actually cut into batteries in a while, generally only replace them

Stud finders don't actually find studs. They find changes in reflected (inaudible) sound waves. So, there is something there that is more dense than the sheetrock (or whatever) you have over it. Could be pipes (probably not unless you're drilling into a "wet" wall, usually reserved for behind toilets/showers/tubs), could be you've got metal or metallic studs (some construction, especially high-volume housing), could be wires just in the exact place you're scanning. Try scanning above and below by about a foot. If you're still getting a metal return, you might want to consider relocating your project.

Hey, I mean that's cool, but you're relying on the memories of the small number of people who read this post. I just don't think this is a very effective way of getting the message to the people that actually need to hear it. Maybe ... stickied comments here and on the original sub? I guess?
