i recently took my 5Gpod up to the mountain for the 1st time (rockin while while boardin is the best). the prob was that the battery died from full charge after like 2 hours. now it was cold that day (like 15-20 F), and i think the battery loses power when chilled. luckily i had a few heatpack hand warmers so i stuffed 2 into my pod pocket and the battery went up to like 2/3 full and played till i was ready to go home. any one else have similar issues w/ pods in the cold?
