Star Dogg, talk to Li Ping about your requirements. He has the best reputation when it comes to LiFePO4 batteries. Send him plenty of pictures if he needs them of your current setup and describe exactly what you have and what you want out of a new battery. You can check out his website at
http://www.pingbattery.com. His email is on his site as well. Get the 5A chargers when you get to that option and you'll be able to recharge your battery very quickly.
Good luck and keep us informed on your results.
