MacBook Pro 2017 with touchbard battery replacement.

Hello. When are you going to support macbook pro 2017 with touch bar battery replacement? I could not find any battery in this site (Its my first btw). If this is not supported yet can you recommend a site where I can find a battery? I dont like amazon because seller might send fake batteries and this the only site that I trust for parts. Thank you and really appreciate it.

PS: how can i protect my battery from bloating? im a developer and my mac is just plugin all the time.
