Stupid question, I can charge the Di2 via junction box with a battery charger can't I?
If it has a cylindrical battery, yes. If it has the BTR1 that you'd normally put in a dock to charge, that kind won't charge through the junction.
by a battery charger you mean a powerbank? or the original DI2 charger?
