Got to do it ,tired of being nervous about running out of juice at the end of a tournament day. I'm looking for a lithium battery and charger to run 2 carbon 9s, 2 carbon 12s,hydrowave and any additional led deck light I will install in the near future. Has anyone done this? Who should I talk to,most battery web sites are so vague its difficult to figure out what is available and how much it costs. Thanks
