Only ICON's spec sheet names a base pack and a named upgrade, both lithium, no lead-acid option on this sub-line's own sheet. Eco Battery publish two packs at the base voltage and capacity — a Thru-Hole and a Skinny, different case shapes — and ICON's “51V/105 Ah” does not say which; both are shown for that reason. Check yours before buying. — applies to some of the listed carts, across ICON Electric Vehicles
Only ICON name this pack for this model and give no alternative — every ICON X sheet leads and ends with lithium, where ICON's older i20/i40/i60 range leads with a lead-acid option and lists lithium as an upgrade. ICON's own FAQ says Eco Battery is “the exclusive factory-installed lithium battery brand on all 2025 ICON EV models and newer”. Eco Battery publish two packs at this exact voltage and capacity — a Thru-Hole and a Skinny, different case shapes — and ICON's “51V/105Ah” does not say which; both are shown for that reason. Check yours before buying. — applies to ICON Electric Vehicles i20X, ICON Electric Vehicles i40FX, ICON Electric Vehicles i40X, ICON Electric Vehicles i60LX
Only ICON's spec sheet names a base pack and a named upgrade, both lithium, no lead-acid option on this sub-line's own sheet. Eco Battery publish two packs at the base voltage and capacity — a Thru-Hole and a Skinny, different case shapes — and ICON's “51V/105 Ah” does not say which; both are shown for that reason. This same product page's own feature list states something different — “AGM Maintenance-Free or Upgrade to Lithium” — so ICON's own pages disagree about whether this vehicle ships with lithium or lead-acid as standard. This pack reflects the spec sheet's own lithium reading; it does not settle which account is right, so check which battery is actually fitted before ordering a replacement. Check yours before buying. — applies to ICON Electric Vehicles i60 Commercial, ICON Electric Vehicles i60L Commercial
Only one of Eco Battery's two 51.2V 105Ah packs — Advanced EV do not say which — check yours before buying. — applies to some of the listed carts, across Advanced EV
Only the EV1 generations Eco Battery name on the bundle itself — 2017-21 (Toyota Neos MCU) and 2021-23 (ADEV MCU). They split this cart by MOTOR CONTROLLER and not by model name: the 2017-21 cars carry a Toyota Neos controller and the 2021-23 cars an Advanced EV one, and which bundle fits depends on which of those is in the cart. A 2021 EV1 sits on the boundary. Advanced EV publish five EV1 models — the 2, 4, 4L, 6 and 6L — and Eco Battery name none of them, so the claim is about the line and the controller rather than about a particular body. Check yours before buying. — applies to Advanced EV EV1 2, Advanced EV EV1 4, Advanced EV EV1 4L, Advanced EV EV1 6, Advanced EV EV1 6L
Only an Onward that left the factory with lead-acid batteries — check yours before buying. — applies to Club Car Onward 2 Passenger, Club Car Onward 4 Passenger, Club Car Onward 6 Passenger
Only an Express that left the factory with lead-acid batteries — check yours before buying. — applies to E-Z-GO Express L6, E-Z-GO Express S2, E-Z-GO Express S4, E-Z-GO Express S6
Only the RXV family. Eco Battery write "EZGO RXV" and name no year or trim, and this catalogue holds three RXVs — the RXV 2, the RXV Fleet and the Freedom RXV Fleet. Some of their RXV bundles do narrow it, to Samsung Gen1 for 2017-2021 or Gen2 for 2022 on, or to the factory metal tray rather than the plastic one. Those distinctions are about the pack and tray the cart left the factory with, not about which RXV it is. Check yours before buying. — applies to E-Z-GO Freedom RXV (Fleet), E-Z-GO RXV (Fleet), E-Z-GO RXV 2
Only Epic name the pack by voltage and capacity and not by part number, and Eco Battery publish two batteries at those figures. Both are shown because nothing Epic publish says which, and the two do not fit the same tray: one is a squat block, the other long and shallow. Measure the battery bay before ordering either. Epic's own data sheets, last revised 19 July 2023, give the battery as 48-volt sealed lead-acid instead — the shop page is the newer of the two and is treated as current. Check yours before buying. — applies to some of the listed carts, across Epic Carts
Sources do not establish: Which of the five EV1 bodies this was listed for, and whether the cart's existing charger and on-board computer suit a lithium pack. Eco Battery name the line and the controller, not the model, and they sell charge ports, pigtails, interlock relays and bypass adapters as separate products.
Applies to Advanced EV EV1 2, Advanced EV EV1 4, Advanced EV EV1 4L, Advanced EV EV1 6, Advanced EV EV1 6L
Sources do not establish: Whether the cart's existing charger and on-board computer work with this pack. Eco Battery sell charge ports, charger pigtails, interlock relays and OBC bypass adapters as separate products, which says a conversion often needs one — but the bundle listing does not say which of them this cart needs. Read the bundle's own contents before buying anything.
Applies to Club Car DS, E-Z-GO Freedom RXV (Fleet), E-Z-GO RXV (Fleet), E-Z-GO RXV 2, E-Z-GO TXT
Sources do not establish: whether the pack fits this cart's battery bay without trimming, and what the charger must be. The chart gives a verdict per cart and no dimensions.
Applies to some of the listed carts, across Club Car, E-Z-GO, Yamaha Golf Car
Sources do not establish: Epic name the battery's figures and its maker but not which of that maker's two 51-volt 105 amp-hour cases goes in. One is a squat block and the other long and shallow, so which one a given cart takes depends on its battery bay — and the bay has to be measured before either is ordered. That is a fitting question rather than an electrical one: both packs are the same voltage, capacity and chemistry.
