NiMH- A must for speed
 

After charging my batteries with my peak charger I put 'em in and noticed a dramatic increase in speed, and cooler batteries. This is obviously due to the NiMH's ability to put out more current due to lower internal resistance. All those who use alkalines-stop:D . Note these are the Radio shack NiMH AAA's that come with the XMOD charger, I just bought some seperate.
