Compatible carts
Only the model family RoyPow name, which is "RXV" with no year, trim or voltage given. E-Z-GO have built RXV carts since 2008 and this catalogue holds three of them, so the claim attaches to the family name and not to a particular machine. Check the cart's own voltage and the size of its battery bay before relying on it. Check yours before buying. — applies to E-Z-GO Freedom RXV (Fleet), E-Z-GO RXV (Fleet), E-Z-GO RXV 2
Sources do not establish: whether the cart's existing charger, controller or on-board computer will work with a lithium pack. RoyPow say nothing about any of the three on these pages, and a lead-acid cart's charger normally cannot charge lithium correctly. The pack is listed as fitting the cart, with nothing stated about what else the conversion needs.
Applies to E-Z-GO Freedom RXV (Fleet), E-Z-GO RXV (Fleet), E-Z-GO RXV 2, E-Z-GO TXT

Only the model family RoyPow name, which is "TXT" with no year, trim or voltage given. E-Z-GO have built TXT carts since the 1990s, at 36 volts and later at 48, so a TXT is not one machine. Check the cart's own voltage and the size of its battery bay before relying on it. Check yours before buying.
