how many watts are you pulling with the APC 15x8 props?.. and this power level is fine for flying off grass?, do you wish you had more?
If I understand correctly, you are using two 3s packs per nacelle in series, each pack is 5000mah so you essentially have a 6s 5000mah pack per nacelle.. and after a 12 minute flight it took 2200 to recharge one of the 6s pack.
Are you using one or two chargers?, yes one charger would take forever. It sounds like 5000mah batteries are too much, you could get over 20 minutes of flight time with them. You probably could save some weight with 3000mah packs and still fly 12 minutes. It is good to have an excess of juice.
is the flight speed adequate with the 15x8 props?.. they definitely have a lot of thrust to get off the grass.
Video would be nice to show electric deniers
