6 Miles is much less than I was hoping to hear. It seems everyone has different results, which is to be expected, with differing weights and type of route. I will have to wait and see if the SLAs will do what I need them to.
Has anyone read about the firefly battery by Caterpillar Co? They will be producing a lead acid battery with a carbon foam core, which they claim will have 4 times the capacity of a similarly sized normal lead acid battery. The only questions are when it will become available and cost.
