Hi guys, I left the "On Button" on my M5. It drained the battery, obviously. The last time i left the battery on, the battery died. I could no longer charge the battery. But someone told me that shouldn't happen. That i should be able to charge the battery and be ok. I am very confused. I bought a new free fly charger, thinking that it might be my charger. I've been through 3 batteries already with this daggum M5. I'm so frustrated. I mean it's a great piece of equipment, when it works. But the batteries,,, it needs major babysitting and major care. With todays, run and gun schedule, who has time to babysit these batteries. It should just be plug, leave and play. /rant.
