Hi Guys,
Is it possible to charge a Di2 battery without going through the Shimano SM-EW90 junction box?
Cheers.

AFAIK, you need a junction box (somewhere) to plug the battery charger into. I've used a separate box and Di2 cable to charge a spare battery before (outside the bike).
If you are an electronics wizard, I'm sure you could whip something up, but it isn't practical.

I mean, the battery itself is a two terminal device (at least the external btr1 type). I imagine any off the shelf li ion charger should be capable of charging 2 series cells should be able to do it.
You'd just have to make a custom etube connector. That's not a bad kickstarter idea though. An external battery bank for recharging di2 on the go.
