I am going to be using GP3300 7 cell packs in my Corona. I have a GWS charger and an MRC Quick Charger. Would either of these be suitable for charging the 3300s? If not, what would be a functional no frills charger? I realize that there are lots of high end ones out there, but for now I just would like to get one to help keep me in the air

Thanks, Howie
