I only remember throwing mine on the charger once, there might've been a brief second attempt in a hotel later in the race. I'm running it down now because I've never actually experienced what happens when it does go flat...
Di2 is great for travel too - much quicker to unplug a di2 cable and remove a derailler or quickly remove aerobars for packing.
I would love to have a smaller charger (or a bigger battery) but that's a nice to have - not many people race their bikes for 4000k!
It definitely removes hand fatigue which I have had riding/racing cabled bikes during 24hrs or audax. This was the first time I've used road Di2 and the first time I've used hydraulic road discs and once I'd set them up they were both lovely and unless there's a specific reason I can't use them I will likely have them on my bikes going forward.
