Good find on that RoyPow battery, MCJEFE ! I would probably do that if I hadn't purchased the cells already ! But I do need/want more than 105ah capacity.
Really? 1.7ah per mile with your EZGO RXV AC? That's quite efficient. It has the Curtis 235A controller(?). Regen Braking?
The EZGO Elite Lithium uses Samsung SDI cells.
I like the kick-in-the-seat acceleration performance of the EZGO 72V cart. Give it a test drive next time you are at TVGC.
The only real problem with the lithium cells is that over time the liquid electrolyte will eventually evaporate out of the cell (like electrolyte capacitors). You really need to slow charge the suckers so they don't get too hot...Perhaps 0.3C maximum to get extended life from them...Maybe 15 years. It is also a good idea to have a BMS with low temperature cutoff since charging at less than 32F will ruin the lithium cells....Granted, not a big problem in Florida.
