I've converted two old nitro planes to electric and working on my third conversion as I type. It is always a struggle to balance the plane without having to add dead weight (which I absolutely refuse to do, especially on an electric). So here's some tips.
Mount the ESC as far forward on the motor box as possible. Which as @ChickenBalls said will also help on cooling.
Mount the battery on the underside of the plane as far forward as possible (but save this step for last to balance it out). On my first conversion I had to make an extended battery mount that actually extended out past the firewall about 1/2".
On my 2nd conversion which was a tricycle, I added a 1/2" spacer block to extend the nose gear forward. That was a big help.
I also used a Great Planes adjustable motor mount which allowed me to fine tune the balance by sliding the motor back and forth.
And obviously mount the receiver as far forward as possible.
Using all these tricks helped me hit the CG mark without adding any dead weight.
