and the temps were 120 to 128.is this normal? i know the battery is getting a lot of air flow from the top but what about the bottom.the bottom of the batt
is sitting on the bottom of the tray,how do i get more air to flow to the bottom to keep it coooler? or is that each cell is a difference tempeture.is that normal,or is one or two cell going bad.any help would be great.
