i took it out first thing this morning and had 5 excellent flights. i came home and decided to go back out to the same spot about 5 hours later.
All on the same day and no additional charging? and its most likely your flight pack was only a 6/7oo mah and had they received a full 14/16 hour initial charge as well as a simple charge just over night? You simply dumped your battery, that's what happened.
Forget the failsafe learn good charging practices for the type batteries you are using and yes the tester you linked is a good one and would work well for you
