Hi, all, very new here and i have a question

[Maisius]

I pick up a new eMtb in a few weeks time. Done it on a cycle to work scheme, so I am limited to £3000. I have chosen a Merida e140 400(2022) model. However this obviously limited the components on the bike.
I want to upgrade a few things. Does this diagram look correct. I have researched all over the Internet and come up with various answers.

Thank you all for looking

forgive me if this is a stupid question.

On the right hand side that Internal di2 battery not needed. Yor ebike battery will power the derailleur. Since they are all connected. Actually I am not even sure if system accepts that battery since there alredy is a power source (ebike battery).

Also consider some display instead of ew-en100.

Also your motor has to be re-programmed to accept a di2 shifter. This can anly be done by shimano service center.

Also you don't need two sm-jc41.
Motor has multiple ports and I think most displays have too.

Thank you very much for the information, that all makes so much sense, so is this new layout more correct, it is much simpler.

Thats correct and considered the usual set up in ebikes.
