ok did some 48 volt agm pc925 and 40ah 3C lith batts the last couple of weeks.....


4 agm pc925 is 100 pound pack

4 of the lith was 60 pounds


agm best out of 5 runs was 11.896 @ 48.64


lith best run 11.704 @ 49.83 mph

this test was on my green drag cart with me driving arounf the 800 pound range....


on a 144volt pack it will save 120 pounds....

now the trick is to find a better lith C rating for more power...
