ICON Electric Vehicles i20X Replacement Battery

Other packs the manufacturer names for this model

ICON Electric Vehicles list more than one pack for this vehicle. Capacities differ, so check which one your cart shipped with before ordering — and confirm with the manufacturer either way.

  The vehicle's own maker naming the battery's maker and figures, which is as direct as a fitment claim gets — and ICON's own figures do not distinguish between Eco Battery's two same-voltage, same-capacity packs, so both are shown. ICON state 51V and 105Ah; Eco Battery's packs are 51.2V nominal and 105Ah, the same pack named at the round voltage. Read it in the direction it was written: ICON say a 51V/105Ah Eco Battery pack goes in this cart, and Eco Battery's own design is exclusive to the ICON family of brands, so a shop-bought pack under the same figures elsewhere is not necessarily this one.

  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.

  Fits as it is. ICON list this pack for this vehicle in their own specification sheet and name no lead-acid alternative, so no adapter, no bracket and no charger change is implied — it is what the vehicle is built to take.

Replacement options from other makers

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.

Only a 51-volt system, which is this cart's stated voltage and this pack's — 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 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.

Two first-party figures compared, with neither company naming the other: this cart's maker states a 51-volt system and Trojan state 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.
