Tight fit! The CF straps work, but ideally the upper cf piece would need a slight trim(tight against a 3700 cell). I put 6 gp3700 cells in the truck and got the strap tightened down, with some effort. A small spacer on the fixed end(side without the thumb screw) to raise the strap and a slight trim of the upper cf strap would allow them to work perfectly.
