well I've given up on the alarm battery. the 2nd one went today. It didn't leave me stranded but I couldn't go out to play today and that makes me MAD
anyway after hours of searching I came across 2 US sites;
motydesign and Ballistic EVO2 50 4-Cell Lithium Battery
I went for the Ballistic as its orange and suits the tracker colours
both will fit inside the seat area and the Motydesign one would prob be
easier to fit, but who said anything about looks being easy?
I got a meet coming up in 3 weeks, lets hope it arrives before then
