I am also using Powerbox products in all of my planes and never had a single issue with this setup for hundreds of flights. My batteries are mounted in the nose, so I need extensions anyway to connect the batteries to the PB. When I solder the extensions, I simply "Y" one branch with an MPX plug at the end. Works perfectly and as explained by Bob, the PB is smart enough to always use the battery with the higher voltage. This way they drain about the same, although one of them also powers the e-gear.
