Di2 Battery Hack Question
Has anyone broken down an internal di2 battery to make it smaller/more flexible so it may fit into a tiny frame hole
Context - I have a slice RS - which has very small frame openings and cannot fit a standard internal battery, but am wondering if i broke down a btr2 and extended the wiring loom with soldering whether it might be safe to make the battery a bit more flexible ie (chipboard, flexi wire, battery 1, flexi cable, battery 2, all wrapped in some flexi plastic or loosely heatsrunk heatshrink.
Anyone done this?

Also does anyone know how big the non-modifiable electronics on the barend port are - I could modify it to sit in the plug in a pro missile evo if the vital part is 14mm or smaller.

If you gutted a battery, you could probably swap the cell/s for something with a different form factor if necessary. What's the deal, does a Slice RS have an ISP?

Slice RS seatpost is super narrow... If I recall maybe 2cm length and 7mm wide.. it was probably right on the limit of the 3:1 ratio and as narrow as possible... They used to mount the big fugly di2 battery under the BB/rear brake area... I owned one, it was absolutely awful to setup!!!
I'd try to get hold of a dead battery, to see what the biggest internal part is aside from the cells. I think LiPo cells are all basically just a flat sheet that's folded or rolled up anyway, so there should definitely be scope to get cells in there.

Yep seen that video. Its essentially 2 AA battery plus the chipboard. Seems that if deconstructed I could get it into the downtube. My bars are pro evo missiles - so too narrow.

Better if you can get the weight down low anyway.
The TT is a pig at almost 9kg. With a 71kg pilot plus gear not sure it will make a big difference in terms of flickability where a 150g battery sits.
