Hi guys, I got a Bamboo GTX overseas and recently came back to the USA. The only way I was able to ship it back to the USA was by removing the entire battery assembly. I thought now would be a good chance to replace the battery cells but after reading a few guides, I see the word BMS popping up frequently. Do I need this and any other original parts from the battery assembly to create a new one?? Sorry, I am complete noob here I would appreciate any help and any links that can help me better understand the whole replacement process. Thanks!
