Another guy suggested this? http://www.hobbyking.com/hobbyking/store/__11903__Turnigy_nano_tech_1300mah_3S_25_50C_Lipo_Pack.html which would fit perfectly into the casing I am thinking of getting, is it okay? He also sent me a pic of a 1500mah in his mod though the casings height is 22mm and the exact same battery I checked was 28mm so dunno how it fitted.
