I would suspect that there might be some issue with hooking different types of batteries in series. I know I could do 12 Ds, but then you have more pieces to deal with, even in holders. Electronics whizzes, please help. Allister are you there?
Probably not wise wise to mix the battery types. What sort of conditions made you decide to upgrade???? Although after hitting Home Depot today, I'm either going to go with a 14.4 NIMH (and overV) or keep looking for a smaller SLA. Because of the hills, winds and speed that I travel, I don't have the luxury of getting a full 4lb 12 V battery.
