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 Acid 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 Battery Technology is ready to take electric golf carts into the 21st century. Our lithium golf cart batteries charge 2-3 times faster, can be fully discharged at full voltage, last 5-10 times longer and weigh 1/2 as much as AGM batteries.
