you can't treat Lipo batteries like "normal" batteries... I have screwed up 2 of them by over discharging them,, which is what is sounds like happened to yours.
after use they should be recharged and stored charged.
I store all my batteries in a metal container and inspect them every 2 days to monitor their condition.
tossing a lipo in a bag after using it.. and forgetting it for a month is a mistake.
