I am quite sure the Samsung SDI lithium battery pack in the EZGO Elite uses Samsung INR18650-29E7 cells in a 14s20p array (280 cells per pack). There are 2 of these packs (560 cells total) in an EZGO Elite 4.2 that TVGC sell.

Each cell weighs 45g x 560 cells for a total of 25,200 grams or about 56 pounds of lithium battery in 2 packs. For reference, one Trojan T875 lead-acid battery weighs 63 pounds...ONE!
56 pounds of INR18650-29E7 cells containing about 50 cents of SECO electricity will propel the EZGO Elite for 60 miles. Impressive.
560 INR18650-29E7 cells can be purchased in bulk for under 3 dollars each or about $1600.
