Neddy,

I really like peak chargers. I also like higher capacity (say Nickle-Metal Hydride) batteries. However, part of the problem can be solved by reading and learning about the batteries. After you have soloed, you will be able to fly a lot longer because you will no longer have the instructor stopping you before the battery gets down to its Nominal or Standard voltage.

There are many days that I start flying at 5.0 volts. Stopping when the battery drops below 4.8 is a conservative approach.

Makes no sense to stop at 5.0 volts.

Sorry, that is about as polite as I can say it.
