Ok, that's a good point. It does seem to go for days without needing a charge. I still need to power the converter though. So I guess I'll stick with the P O L i have and use it for that. Thanks man. I'm planning on getting that thing done and ready for install next week while I'm off. Maybe I can get it installed, even thought he rest of the system won't be anywhere near done. Lots to come that's for sure.
