I've read a post by one of the MAXAMPS support folks that it isn't good to store LiPo with full charge as it could ruin the battery. The post was in response to someone who had stored his LiPo for about 6 months in a cold climate and was having problems getting a charge into it.
label on my LiPo indicates it should be stored at a particular voltage...I guess I still need to check and see if that is the voltage I would see at about 50% capacity. I'm assuming as much at the moment.
LiPo rocks!
Only problem is stuff starts falling off the truck before my LiPo reaches cuttoff so I have to remind myself to reinspect the car a few times during the run!
