Shimano ultegra 11speed di2 mini group

Hi all - I’ve got an external battery 11 speed di2 group I’m looking to move on as follows

6770 shifters
6870 front and rear mechs
Y cable junction box
BB shell mounted junction box
All cables (all have been cut and re soldered to fit into non di2 frame - all function perfectly)
External battery and cradle
Battery charger included

I’d like £400
Can do collection around London Bridge/Waterloo or even Tunbridge Wells or happy to post it

Photos to follow

Let me know if you split it

what would you want if split?

Depends on the price. Rear mech, cables & junction box, and the battery.
I'm also looking for an old Di2 battery that's defective or that doesn't hold charge anymore btw.

ok... may I ask why you're after a defective battery?

Cause they are freaking expensive for what they are and I could easily make a DIY one with 18650 cells, I just need the PCB that comes with official ones.

ah yeah understood...

I might be interested the front derailleur if splitting?

I might be able to help with the battery, drop me a PM. Its the seat post version, the connector is damaged, so the batteries and the circuit board are fine.
