The problem I have is that I usually just replace battery packs when I feel that they are not going to be reliable to me. I value my planes more than what a replacement battery pack costs.

this is also a good point, Iuse to "test" my batteries by how many 10 minutes flights I can get before thelow batt alarmstarts beeping. Ithink any 600 to 750 mAh pack should give you at least 5 flights.
