Epic Carts E40FL Replacement Battery

Battery compatibility evidence and replacement options for the Epic Carts E40FL, each with its source.

Last updated: 16 September 2026

We have not documented a battery sold by this vehicle’s own manufacturer for this model. The options below are from other makers, each shown with the evidence behind it.

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.

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

Bolt's fitment guide lists the FactorySync harness, part 33-031, bought separately, and the FactorySync firmware for this platform.

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.

Bolt name these six Epic models and these years for this kit, in their own fitment guide — the pack maker saying what it fits, not the cart maker, since Epic themselves fit Eco Battery. The harness is part 33-031 and is not included in the battery's part number.

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.
