[Closed] external Di2 install

Hi,

decided to convert my V1 tripster to external Di2 and wanted to check on what I need. apart from the mechs and shifters i think its

1) junction box A (MT800)

2) battery BT-DN110

3) battery case SM-BTC1

4 ) charger (SM-BCR2)

5) cables  / ducting / zipties 🙂

I'm planning on using the SM-BTC1 external battery case so I don't need a junction box B.

Was also planning to get the MT800 display unit rather than a standard junction box - partly because I like the idea of a screen but also because it supports wireless . Does anyone have any feedback on using that on a roadbike - is it better just to get a standard junction box A?
