My advice would be to stay away from those charging issues in the first place and run 2 x 4S batteries.
Most of the people I know that fly with big power (Over 6S ) all fly with 2 batteries in series 8S = 2 x 4S , 10S = 2 x 5S etc
All my big planes run with this system it gives flexibility with installation because you have a lot more options when it comes to the physical size of the batteries that you can use.
I keep my batteries in pairs and always fly them as pairs, that way the load on both batteries is equal and they are matched for reliability.

PS: Hello from the northern beaches, just joined WRCS and as you would expect they are a nice bunch with an absolutely awesome field.
Miss you guys.

Hi Gazz, On Friday I bought 2 planes from a WRCS member, his name is Phil and is a lawyer, really nice guy. He is mainly flying 2 mtr planes now so he waas selling off his excess. I got a 1200mm Eflite PT 17 Stearman, balsa, and a 1100mm P-47. Hope you enjoy the new Club mate, you will be missed at PRCAC.
