Hi All

I wanted to ask any of those Di2 specialists if buying the above battery rather than the older version one (SM-BTR2 Di2) has the following benefits on a Ultegra 6870 system:-

allow for wireless access to the use the E-Tube app to run what ever process on the mechs/shifters?

I am 90% complete of the system, just need to buy front and reach mech with a battery all to be installed on a P5. Issue is, I dont think there is value to buy 9070 di2 when the 9150 is ready to be shipped (and ultegra is priced very competitively for a TT bike I will use very little). It would be a sensible upgrade next year for me. But the choice of battery could end up being important if i upgrade and cannot for any reason use the SM-BTR2.

This is my first dabble into Shimano, ever.

Thanks,

The new battery will be necessary to utilize the new E-Tube mobile apps as well as enabling syncroshifting features. You will also need the newer D-Fly unit to utilize the E-Tube mobile apps.

There is no downside to buying the newer battery besides slightly higher cost.

Downside to the old battery is that it’s next to impossible to find… everyone is out of stock. Can go used (if you can find one), but batteries are consumables in my mind.

E-tube! eTap is a Sram product.

Sorry, but that was driving me nuts.
