The battery for this vehicle

51V 160Ah LiFePO4 Gen3

SKU A-051160-06

OEM

Advent HD CX’s own specification gives its battery as ECO 51.2 Volt 105Ah Lithium Battery Pack - Upgrade ECO 51.2 Volt 160Ah Lithium Battery Pack, while this pack is 160Ah. 51V 160Ah LiFePO4 Gen3 is documented by the manufacturer as fitting this machine, but it is not the capacity the machine’s own specification states — check which pack yours has before buying.

Why this pack is listed for the Advent HD CX

“BATTERY: ECO 51.2 Volt 105Ah Lithium Battery Pack - Upgrade ECO 51.2 Volt 160Ah Lithium Battery Pack”

The manufacturer's own statement for this pack. Reported, not endorsed — confirm with the manufacturer before buying or fitting.

Only the factory upgrade option. Advanced EV list "ECO 51.2 Volt 105Ah Lithium Battery Pack" as standard and "Upgrade ECO 51.2 Volt 160Ah Lithium Battery Pack" as the alternative, so a cart bought without the upgrade has the 105 instead. Check yours before buying.

Maker lists it as a direct fit. Advanced EV offer this pack as the factory upgrade on this cart, so it is fitted in place of the standard pack by the maker or the dealer rather than retrofitted. The cart also leaves the factory with a lithium charger — Advanced EV name it as an "ECO 51.2 Volt 15Ah Lithium Onboard Charger" — so unlike a lead-acid conversion there is no charger to replace.

Sources do not establish: Which 105 amp-hour pack the standard cart carries. Eco Battery publish four at 51.2 volts and 105 amp-hours and Advanced EV name none of them, so only the 160 can be resolved to one battery.

Replacement options from other makers

Manufacturer documentation explicitly identifies this as compatible.

Neither manufacturer names the other. One publishes what the device requires, the other publishes what the battery does, and the two are compared here, including wherever they do not meet.

“BATTERY: ECO 51.2 Volt 105Ah Lithium Battery Pack - Upgrade ECO 51.2 Volt 160Ah Lithium Battery Pack”

Only one of Eco Battery's two 51.2V 105Ah packs — Advanced EV do not say which — check yours before buying.

Only the 48-volt system this cart states and this pack shares — check yours before buying.

Sources do not establish: Everything except the voltage. Trojan names 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 publishes dimensions (544 x 325 x 266 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.

The pack the CX ships with, as Advanced EV state it. Not at the OEM tier, and for a specific reason: Eco Battery make two 51.2 V 105 Ah packs, a Thru-Hole and a Skinny, and Advanced EV give the voltage and the capacity without naming the case. Both are recorded, neither is presented as the one fitted, and checking the case in the bay before ordering is the reader's job.

Two first-party figures compared, with neither company naming the other: this cart's maker states a 48-volt system and Trojan states a 48-volt 171 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.
