A volt meter with a load is a good thing to have. I check my packs before each flight then usually check before each flight after that. When I get close to say 4.8 volts then I put the pack on a field charger and start the process over again. On those real lazy days I check before the first flight then on the third flight. My flights last about 10 minutes and I get about 5 flights per charge. Even if I have enough juice left in the pack I put it on the charger. Most of my servos are digital and all of my planes are stunt planes of some sort, I don't have a float around plane at the moment. I only take the trainer out when I have a student or the wind is up. My packs are all nim
Are you talking a 4 or 5 cell pack? If 4 cell why are you charging when the voltage gets close to 4.8? Seems to me you are wasting most of the battery charge. Also do you ever slow charge or do you always use the field charger?
