Question #1..... 60Hz vs 50Hz?
Forgot to say, they're also multi-frequency. 85 to 265 VAC and 45 to 65Hz.
I use one and DonTom has about 20 of them.
I doubt it would fit in your lower storage section. The cable with the Andersen connection is rather thick and not foldable. It's also pretty heavy.
Don and myself go with a theory that it saves stress on the onboard charger, and it cuts your time in half (with 1) so that's nice.
They are a great backup if your onboard charger goes out as well. The Quiq charger can charge by itself.
For longer trips the charge tank is the way to go for your bike. It'd only take about an hour for about 90% charge with a 7.2 battery.
If you still want a Quiq charger it does need to have been programed for the Zero BMS interaction. Your local dealer should be able to get you one. They run $600 U.S. so a bit more in Britain.
Oh one more thing.
You will need a separate circuit for the Quiq charger and the onboard charger, if your using a wall socket. They will pull too many amps and throw your breaker.
Well at least in the U.S. with 20 amp breakers at 120V.
A charge tank would be great, but it's more money, more weight (that can't be removed, I wouldn't need it very often), and the tank storage is really handy.
The current draw wouldn't be an issue, the limit is 13A at 240v which is a bit over 3kW and using the Quiq with the onboard would only be about 2.3kW.
I don't think the cable would be the limiting factor, the way it would go in the compartment (if it fits through the hole) the thinner input cable would go facing down and then the output cable would be facing up and should have plenty of room to be coiled up.
As you've got one would you mind taking some measurements for me? I need the height, width, and depth of the main body of the charger as well as how far the mounting brackets stick out (if they're not removable), noting which dimension measurement they add to.
