Iv been looking for a day or two now but does anyone know the biggest mah 6s or 3s combos can you use on the big rock 6s? I have 5200 and they fits perfectly I but would like to have longer run times amd don't want to spend the money on batteries not knowing if they will fit since this is my only 6s rig in my whole rc fleet Everything else is 3s or 8s lol. Pic for fun
