The battery is performing Very Good , it is powerful as I installed the 72 V pack on my Golf Cart , 2002 Ford Think Neighbor. The only advice I have on the Manual is to add in there that you note to turn on the Breaker Switch on the battery after installation ! So far I played 3 -18 hole rounds of golf and still have 40% battery , that is approximately 20% usage of battery per 18 hole round of Golf , of course that depends on the terrain of your course , My course has quite a bit of up and down terrain approximately 4.5 to 5 miles per -18 holes. That is still quite a bit of golf on one charge !
