But based on your question, it sounds like you are trying to 'push the envelope' and fly on a marginal battery. If so, please make sure your home owners liability insurance is paid up, you are a current AMA member, and that you have a plastic bag with you to collect the remains of your plane after you finish with your suicide flight.
Perfect example happened today... a guy showed up at the field for the maiden flight of his Cap-232 after some repairs. The controls just quit and the plane went in. One of the more experienced guys checked his Rx battery afterward and it was dead. The battery had been put on a charger last night but there have been a few blackouts around here lately, especially last night. The battery did not fully charge. Had it been checked with a meter that applies a load as you mentioned before the flight, the crash would have been prevented.

Another example... I went out flying with a friend of mine after work. He had forgotten to charge the night before so he threw it on for a "quick 30 minute charge". Problem is, he had a habit of this. Right in the middle of a flight, the controls went dead and the plane went in. A gorgeous, one of a kind, scratch built plane was destroyed.

I now keep track of all my batteries, cycling and testing them regularly. The expanded scale volt meter is in my flight box and it's going to get used before every flight. I like my planes too much to lose them to something as stupid and preventable as an under-charged battery.
