Ever since the first Golf Cart was invented by JK Wadley of Texarkana in 1932, they have been powered by Acid Lead Cell batteries. The Glass Mat (AGM) battery became widely used in the 90's but this too was based on lead technology .
Both of these power storage devices have great drawbacks, they must be maintained, can't be over-discharged, only produce about half of their stored energy and are very heavy.
Lithium Technology is ready to take electric carts into the 21st century. Our batteries charge 2-3 times faster, can be fully discharged at full voltage, last 5-10 times longer and weight 1/2 as much as AGM batteries.
