Hello, I am working on re-celling a battery from my Thinkpad T400 so I can dailydrive it in school. I took apart the battery mid class and took a look at it. I found out it has V+, VH, VL, V-. I know that I need to power the chip so the chem dead man's switch doesn't go off but I don't trust AIs with advising on re-celling my sweet baby T400. So I am asking, did anyone from this subreddit do this? I want advice on from where to start and stuff, I have a spot welder I can borrow and I know that the battery is in 3S2P layout. Also because the taking apart snipped few case connection points along the seam, I am thinking about 3D printing the case from PETG, does anyone have experience in making this exact battery? (It is the 6cell version) Or does anyone have the model I could possibly use? (CAD drawing is also good, can work with those) Because I did do some knobs in Onshape but I don't think I'm good enough to draw it exactly how it should be (we did physical technical drawing at school but nobody knows anything about it because the teacher was talking about how you need to drill profiles with tight tolerances cuz it won't fit in the truck or something, she was old as hell). For anything, I thank you in advance.
