I have one of these to charge 1s lipo's:

I've charged BRB batteries with it, but you have to make an adapter. It comes with extra connectors you can modify. (Watch the polarity!) It isn't as fast at charging as the BRB USB widget.

Yes, the Beeline TX and BigRedBee using a 1-cell LiPo battery, 210mAH and 850mAH respectively. Nominal 3.7V, typically 4.3V when charged and not under load. That charger should take <1hr to charge the smaller one.
If the cell (technically not a battery :wink
has been discharged below a certain voltage (not sure, 3.3, or thereabouts, depends where you read the number on the www) it is not recoverable and needs to be replaced.I generally keep a few spare LiPos around. Some I have killed by over-discharge after a flight and need replacing, and I have had a couple puff up after flights which is usually a bad sign. I suspect it is due to the rapid change in air pressure. Having spares handy keeps me flying

Yes thats probably what happened, the rocket was in a tree for a week, the BRB has a low power shutoff feature even with that on it will shut down the transmitter but still draw. I ordered a bunch of 3.7 LiPo and a charger, transmitter fired right up, thanks for all the help.
