Same here. Sony vtc's and LG he2's only. LG's are available and fairly cheap. I'd recommend buying a set to pair up for the flask.
I originally bought 4 thinking I'd need to have a set fully charged to swap in when the pair in the flask died but that really hasn't happened to me yet. When it gets low(after 4 days usually), I charge it when I go to sleep. If it's not fully charged I'll do it again the next night and that usually does it.
