3cell & 4 cell batteries?

Right now I run a 3 cell 2100mah battery in the 450 Trex. I have an opportunity to buy some 4 cell 2100's. I have the stock Align ESC and motor from an SE kit. Can I run the 4 cells with no issues? Anything to change? Can I run a 3s then a 4s for the next flight back and forth? The spec on the esc says it can take 4 cells but there is no adjustment for it. I guess it will give more power but will my throttle curves be messed up for 3 cells? Anyone try this test?

I think you will have to adjust the pinion or the headspeed will change.....

Yup, you'll need to adjust head speed to not only keep your head within safe operational limits, but without adjusting your gearing, going to a 4 cell will increase your amp draw, risking cooking your controller and motor :).
