Just a quick caveat to charging the battery through a Powerlet outlet. This is intended for those who have Fuzeblocks installed on their bikes:
If you draw power for your Powerlet from a Fuzeblock fuse block, you CANNOT charge your battery through that Powerlet even if it is not a switched circuit. I emailed Curt at Fuzeblocks.com this week to ask him about it and this is his reply....
The input power to the fuzeblock has a diode on it for protection in case someone wires it up backwards. However by placing that there it prevents the unit from being compatible with a trickle charger since the current flows in the reverse direction which is what the diode prevents.
So I apologize but I had to add that feature because of liability and safety issues. On the next version I may add a special input just for trickle chargers.
