[Sleeping911]

i have foung the best dual mod to be the sleeper mod....flip the pcb upside down dremel the box that holds the clip for the charger out (you may want to glue in a piece of plastic from one of the packages with a flap cut out ( i did cant say if its any better with another battery in there anywayz it will cover the hole somewhat and radius of battery will allow you to get the charger clip in there.) and stick in your 2nd battery....or if you want to get crazy stick in a 2.4v 70nimh out of a se in the front and then rip an se battery in half and stick it in the smaller area where the stock 100nim 1.2v was. i also dont recomend dremeling off thepost holding the stock battery in place.
