Thanks all for the pictures. The mirror image of the left battery to the Van's right battery installation is an attractive option and would be my first choice. The hinged front battery box also makes sense. I guess I should have mentioned I will have a constant speed prop, and my concern with the mirror image left battery installation is that it will interfere with the prop controller cable. I'm still assembling the forward fuselage, so I don't have the engine, engine mount, prop cable or PC680 box to decide on a location, but I'm trying to plan well in advance. Can the prop controller cable and cable mount be clocked or installed so that it misses the left battery box?
