Neither manufacturer names the other. One publishes what the device requires, the other publishes what the battery does, and we have set the two side by side — including wherever they do not meet.
“OnePack 72V 105Ah Lithium Battery Pack”
Only a 70-volt system, which is ICON's figure for this cart; Trojan call this pack 72 volts — check yours before buying.
Not established: EVERYTHING EXCEPT THE VOLTAGE. Trojan name one cart anywhere read — the E-Z-GO RXV Gen 1 ELiTE — and it is not this one. Whether the pack physically fits this cart's battery bay is unestablished: Trojan publish dimensions (544 x 357 x 270 mm) and no cart maker here publishes a bay. Whether the cart's existing charger suits it is unestablished. Whether the cart's controller, onboard computer or CAN system accepts a single pack where a string used to be is unestablished. A matching voltage is the start of this question and not the end of it.
Two first-party figures compared, with neither company naming the other: this cart's maker states a 70-volt system and Trojan state a 72-volt 105 Ah pack. A single pack replacing a string changes the arrangement as well as the chemistry — where a cart carried six or eight batteries wired in series, this is one. Recorded at the comparison tier because that is all the agreement of two numbers supports.
