i did a battery mod to my old cm030 which i sold to my freind where i got 2 standard 7.2 batteries it came with hooked them together got my dad to put on a breaker so as to not overload the motor and it lasted for about a day and a half of gaming you just need a power breaker and the voltage is kept down so its not shooting like crazy with the spare parts from the other battery i found out which side was + and which was - and just soldered a ics battery modded so it fitted throught the hole in the top and wrapped around the front of the gun and i put a 20mm rail on it so you could put it on and take it off the gun (but my dad helped me with all of this he's a computer nerd) so do it at your own risk
