I'm doing an annual on a friend's 205 and they've told me their battery dies all the time.
It has this tiny battery that is PMA'd for pa18's but nothing else. There is no 337 or W&B for it. But what I can't understand is the reasoning for it and the styrofoam. Anyone seen people doing this on planes the 205's size? I've seen that battery on lightsports, but was shocked to see it here. It was on it when he bought it.
