I have several 4S batteries, the 2 smallest are a 2200mah and then a 3300mah. The 2200 fits OK but a bit tight. The 3300mah battery has no chance of fitting without carving out some of the power pod. I need to widen by about 3/16 ths. Has anyone modified the power pod in the Corsair to accept the slightly bigger 4S batteries?? Thanks, Ron
