Having a gander. I see some have a fag lighter section, does the car trickle charge through that ? That would be a boon if so, getting at the battery is a pain isnt it !
If the lighter is permantly live then that would work.
I use an optimate on my battery and have the connector wired the battery so it's easy to plug in (however my battery is under the bonnet to pretty easy). You could wire something similar so the connector is accessible. Personally I prefer having the charger connected directly to the battery.
