Seemed a little early to experience diminished power. Purchased five new 12v 20amp batteries that I had nothing but problems with. Trying to find out more information on stock batteries was impossible. Original batteries had Chinese lettering with no English information. Left with a question of were the original batteries lead acid deep cycle or regular? Also, is there a uni (one piece 60v 20amp battery available? Otherwise the trike performs well and is an attention getter.
