Hi ,

My next frame can only be install with di2 internal battery .Shimano BTR2

I knew that SM-PCE1 can be use for diagnostics/firmware update . Can it be use to charge the battery as well ?

Or I still need SM-BCR2 to charge the battery.

p/s - i will list my new external di2 battery/charger soon . not needed

Thanks

You need the SM-BCR2 to charge the battery. I had a SM-PCE1 but it wouldn't charge the battery. The SM-BCR2 has a different cable that plugs into the front junction box, not your standard e-tube like the SM-PCE1.
Gaulzetti Cabron Disc = (weight unknown)
Rock Lobster Team Tig SL Disc = (pending)
Sold: Ridley X-Night Disc = 7.80 kg | Ridley Noah FAST = 6.86 | Ridley Fenix = 6.74 | Raleigh HiLife = 7.46 | Fuji SST = 7.34 | Van Dessel FTB = 7.58

You can update the firmware AND charge the battery with the SM-BCR2. You don't need the SM-PCE1.

Because they didn't have the SM-BTR2 & SM-BCR2 ready for the market when they first released the PCE1?

Do keep in mind that if you have any issues and need to run any diagnostics on your DI2 E-Tube components, you will need the PCE1.
