Bose Sounlink Color Part 2 In depth details dissasembly

I had a lot of questions from the first video, I hope this answers all of them. I searched for the battery model but I did not find anything. My idea in case it will need a replacement is to buy a phone battery or something like that and connect the - + to the ends of this one, keeping the chip. I don't know why are there 4 wires but it s logic, if I connect a new battery where the old battery was connected ( at the ends ) it will work. As you heard/saw, without the enclosement the sound is nothing. It has to do a lot with the speaker radiators (those wide membranes that look like a speaker but have no magnet coil etc.).
