Plus if Di2 goes wireless and gets lighter!

So I now superglue my tabs...I don't think people need see this as a temp fix.... it's stronger than the original, pretty sure the issue is dealt with that easily.

Yeah... shouldn't be necessary but hey... not a hard fix

Me too. Here are photos of permanent repair I've done. UD carbon fibres are going 90 degrees each next layer to make strong both: the tab and the brace. To make sure this piece of carbon wouldn't fly away if ( very unlikely ) debonded, I've milled out plastic casing little bit deeper near both ends of the brace to anchor them firmly. The brace is the same 1.2mm thick as the tab.

Not sure that'll happen. Di2's battery are pretty light and small. And last longer than Etap due to the communication through power line that Di2 use versus high polling rate wireless communication.
Yes, Di2 now have a wireless unit to talk to computer about gearing selection, battery and etc. But that is only a single slow (high latency, low polling rate) wireless data channel. No match for energy consumption of wireless communication that are delay sensitive like shifting command of Etap system.

If Di2 go wireless, it'll gain all the weight saved from wiring through more and larger battery.

Pfff, yesterday I thought I had tough luck breaking an eTap battery untill I found this topic. Holy crap. I've ordered a new one but hopefully won't need to do so every 2 months or I'll go crazy.

I've had this happen as well. Oddly enough both batteries within 1 ride of each other (ca 12k on the groupset). SRAM warrantied them through jenson with no issues.
