I have 2 of teh radio shack GP 3300 batterypacks. The first thing I did was cut teh stock plugs off and go to deans ultra. After that the plusg stoped melting. They last for about 20-25 minuts and give a great punch. They take about 15 minutes to charge at 6 amps. I have had them for over a year and haven't noticed and lose of power.
I have one and plan on getting two more. I have yet to use mine but they are GP3300 cells which i have used before! I have heard great things about them.
