Thanks for all the help gang, you guys are great.

Let me get a couple more things straight with you guys before I quit buggin you (till the next topic). I bought this charger and I have to open my car hood to use it. If I charge the reciever pack a day or two in advance or more (with my car hood open while charging) is it ok to go flying, or should I only fly when I charge the night before. Is the purpose of trickle charge for when you fall a sleep at the field with the hood open and the battery charging? What is the best setup if I have a plane or two and want to fly all day without running out of battery power: bring multiple cars for battery charger charging, use mutiple battery chargers off the same car battery at the same time or get a field box that accomodates a car battery? Lastly, is their any point where I need to worry about having a car battery charger with me because I'm the only one at the field, and my car battery is drained because of charging all my airplane batteries off the car battery?

At least I don't have to ask about kinds of batteries or charging rates because I read the instruction booklet.
