Take a bit of advice on this though Littlewood, put some form of remote access to the battery to charge it in case it goes flat for any reason, a lighter plug sort of affair behind the grille is what I'm using, I wish I'd have thought of it before last week, my battery went flat and I couldnt unlock it or pop the doors, I had to lever the door to unlock it and pull the interior door handle to get in, denting the door frame and door slightly in the process.
