I think I have a real fix that you might want to incorporate into your 701.

 With the battery behind the seat, and the cowl closed, it is a little hard to get a high amperage connection to the battery for a jump start or for charging.  This plug is the perfect solution.

The 75 amp plug is bolted between two aluminum angles, riveted to the side of the fuselage, and covered with tape. To make a high amperage connection, you just peel off the protective vinyl tape, and plug in the pigtail.

The plugs come from DCpower.com and are rated at 75 amps. Their part number is DC75-2 and cost $8.00 for a pack of two. You will also need 4 feet of their awg  6 wire. I got two feet of their twinlead and split it.

Make two 3 inch long angles. The standard Zenith angle is too narrow, so you will have to bend some .025 that is at least 30 mm wide on one side. I used some extra AN-3 bolts to mount the plug to the angles. I then drilled a 5/8 hole in the side skin, enlarged it with the Dremel to a rounded-corner square, and then drilled and riveted the assembly  in place.

For the external wire, you will solder the wire to the metal part of the plug, and tin the other end for connecting to the jumper cables or to the charger. It gets stored in the baggage compartment. The internal wire of course goes from the plug to the battery positive post.

Many colors of sheet vinyl and electrical tape are available, and will cover the hole and blend in with your paint  nicely.

I mounted an Anderson Powerpole SB120 from powerwerx behind the copilot's seat back, protected by a captive rubber cap. I like having the connection behind the sort-of locked bubble door. These connectors are commonly used for charging electric forklifts. 120 amp rating.
