Best charger is Astroflight 109. With the XL3100, you don't wanna go much higher than 5s. So, if I were you, I'd get 2 4s 4400 packs or 2 5s 4400 packs and hook them up in parallel so you get 14.8 volt 8800 mah or 18.5 volt 8800 mah. If you ALWAYS use them together, you can charge them at the same time with the Astroflight 109 and charge it at the 8.0 amp rate. You can fully charge your pack in about an hour then. Heck, you'll easily make the 12-15 minute mark.
