battery pack lifespan?
I am currently building my extra 300s 4 (GP). I am using all new equipment besides the reciever and battery pack. I know the reicever is ok but I am wondering how good thepack is. The pack was in a plane that I only used basiclly one year. Thu there is not a lot of time on the pack (maybe 30 -50 flights) The one thing I am worried about is the pack is about 4 years old. How long can they be good? It didnt sit for years but was probably charged a few times the first year anda few in the years up unti I flew it all one summer. My question is is it ok to use now?
