I went to the hobby store(UGHH) and bought another battery a couple days back, a 5 cell 4.2ah 6v. I haven't put it in the truck yet but if it works out OK I will buy another one of the same to get the run time up to where it is with the lead acid battery. Two of these are still way lighter than the lead acid battery and they will also reduce the charge time a whole bunch. How many amp hours do the batteries that you guys use have?
