Only issue being, Sometimes brands like Toshiba Lock there BMS board such that once you disconnect the battery i.e. once the input to the BMS goes to 0 volts, and it resets, it needs to be reprogrammed to start functioning normally.I've been seeing videos about this but I have no experience in these matters, in soldering and all. I'll still give it a second look. The advantage of doing this is that you get original batteries, and it is cheaper, right?
I had tried this with my earlier Toshiba laptop, Luckily it didn't require much machinery to reprogram as it had the serial Rx and Tx exposed so I did that myself with binary from some Russian ftp links.
But in later versions sub 2010 and later, they had removed that possibility too.
