Once these batteries drop below about 50-60% full charge they will never come back and the life is really short. Sounds like you might just have a bad battery, however, if your using it hard with the accessories you have, you might have killed it.
I don't have those accessories yet. Future planning.
I charged the battery but haven't had a chance to load test yet.
