I am getting my Fastech back up and running. I think I am going to go with the Hyperion 45c 5000mah battery's. My question is; should I just leave the battery tray alone and strap the battery in at an angle? or should I cut the front part of the battery tray so that the battery will lay flat?

I have been reading a bunch on this forum. I intend on upgrading the bullet plugs to 5.5mm on the motor, and will probably run 5.5mm plugs on the battery's also.

my main goal is to have a decently fast, but reliable setup. no nuclear meltdown speeds required.
