My golf cart has an Eco Battery — what does the warranty cover and what do I need to do?

Eco Battery (ECO Capital, Inc.) names the cart brands that ship its lithium packs from the factory: ICON, Bintelli, MadJax, Venom, EPIC, Honor, Advanced EV, Activ-EV, Voyager, ZROX, and Vivid. ICON goes further — Eco Battery is “the exclusive factory-installed lithium battery brand on all 2025 ICON EV models and newer.” Eco also sells aftermarket bundles for other carts (Club Car, E-Z-GO, Yamaha, Evolution, Denago), but a bundle existing for a cart is not proof that cart shipped with one — check the label on your pack.

These cart-maker figures don't line up with Eco's own published terms (below), and Eco hasn't said which set governs a factory-installed pack. Bintelli's 90-day window conflicts with Eco's 60. The safe move: register within 60 days, keep the bill of sale, and file any claim through the dealer who sold you the cart.

• ◆Gen3 — a serial-number tag, “Gen3” and kWh graphics, and dual communication ports. A heated Gen3 adds an “Auto-Heating” icon. The power button is momentary (it springs back).
• ◆Gen2 — a serial-number tag, a power button, and a steel case.
• ◆Gen1 — no serial number and no power button; a plastic or steel thru-hole case. Eco's warranty-claim form can't look up a Gen1 pack by serial.

“Lifetime” is the label, not the deal: after year 6 you buy a new pack at a discount, and after year 12 you get parts only. During the free period you pre-pay Eco $300 for shipping and handling, and Eco may send a certified refurbished pack instead of a new one. Eco hasn't said whether the February 2026 Lifetime terms apply to Gen3 packs sold under the earlier 10-year policy.

Eco's rule, verbatim: “All products must be registered within 60 days of the purchase date. If not registered, the warranty will default to 1 year of coverage.” Your dealer can register it, but don't assume they did — Eco's dealer bulletin says “You or your customer can register.” ICON asks you to register the cart and the batteries separately. Register at ecobattery.com/register with your dealer's name, the battery's serial number, and your bill of sale.

• ◆A non-Eco charger. “Use of any non-approved Eco Battery chargers will void the warranty on your battery” — that includes battery tenders.
• ◆Buying from an unauthorized seller: “Products purchased from non-authorized dealers carry no warranty.” Eco's dealer locator lists who's authorized.
• ◆Selling the cart. Every version is non-transferable — Eco, ICON, EPIC, and Venom all say so. If you're buying a used cart with an Eco pack, assume the battery warranty didn't come with it.
• ◆Wiring packs in series, more than 3 in parallel, pressure washing, submersion, storing it fully discharged, or going over a year without charging it.

• ◆Power: on a Gen3, hold the power button about 3 seconds to switch it off. It blinks when the battery management system (BMS) has a fault.
• ◆Sleep: the pack goes into Power Save Mode after sitting. “To exit Power Save Mode, simply press and release either the remote wake-up button or the on/off button on the battery.” The remote button can wake the battery but can't turn it off.
• ◆The meter: the state-of-charge display needs no calibration and is accurate to ±5%. Read the percentage, not the voltage — lithium's flat voltage curve makes voltage a poor guide.
• ◆Cold: a standard pack won't take any charge below 32°F, including regenerative braking — Eco advises against driving a regen cart when the overnight low is under 32°F. A heated Gen3 warms itself on the charger and charges down to −30°F.
• ◆Storage: charge above 50%, unplug the charger, switch the battery off, and charge it at least every 6 months. Below −4°F, take the battery out of the cart. After storage, fully charge before driving.
• ◆Firmware: Gen3 packs take firmware updates through Eco's EB Power app (Gen2 packs log data and diagnostics). Check for an update if the pack misbehaves.

When a code shows on the meter, Eco's manual says to “record the trouble code and contact your dealer.” Level 1 is a serious fault that will not clear on its own — contact Eco Battery. Level 2 (major) and Level 3 (minor) faults clear themselves once conditions allow.

More range: Eco's datasheets allow two packs in parallel (“Parallel Connectable: Yes, up to 2”), but don't mix generations — “We do not recommend mixing Gen2 and Gen3 batteries in parallel.” Bigger single packs exist: a 51V 150Ah Gen3 is $2,900 and a 51V 160Ah Gen3 is $3,119 on ecobattery.com (read 2026-10-02), with cart-specific bundles priced higher.

Switching brands: on an ICON, Eco is “the only authorized lithium battery approved for ICON EV vehicles,” so a different brand can put your cart warranty at risk while it lasts. Out of warranty on any cart, our 48-volt lithium showdown ranks the drop-in packs — Eco's own Gen3 bundle included — on warranty, discharge power, weight, and cost per kWh.
