On-board charging ?

[Just_Build_It]

I'm considering using an on-board charging method while still connected to the ESC. I did some reading about the topic and I'm curious if anyone here charges their battery via extra plug to the battery so there is no need to remove the battery or body and deal with all that mess. I'm going to use a Y splitter so I can just pull out the extra female for charging that will be tucked away.

Does anyone have any experience with this setup and if so, where is your charging port?
