ECO Battery 48V 105Ah Thru-Hole Lithium Golf Cart Battery Kit

The ECO Battery 48V 105Ah Thru-Hole Lithium Golf Cart Battery Kit comes with a cart-specific installation kit, a 15-amp waterproof charger, a 110V receptacle and a dash wake-up button.

Why it made the list

ECO’s Thru Hole series is built for carts with tight battery space. The pack is sized to drop into the factory lead-acid tray, and the cart-specific installation kit brings the brackets, hardware and meter for your model, which makes it one of the simplest swaps on a wide range of carts.

It also ships with more in the box than most kits. The ECO kit includes a 110V charge receptacle for onboard charging and a remote wake-up button, two things other brands sell as extras.

What it does well

The wake-up button mounts on the dash and turns the pack on and off without lifting the seat. That sounds small until you’ve lifted a seat in the rain to wake a sleeping battery.

The included ECO Lithium digital charge meter shows charge as a percentage, and the ECO Battery app connects over Bluetooth for live data and diagnostics.

The 15-amp waterproof charger handles lithium charging correctly, and with the 110V receptacle you plug the cart straight into a wall outlet like a factory setup.

Who it’s for

This suits owners of common carts who want a clean, factory-style install: Club Car DS, Precedent, Onward and Tempo, E-Z-GO RXV with the plastic tray, Yamaha Drive and Drive-2, and Evolution.

Who should skip it

ICON, Advanced EV and Bintelli carts need ECO’s tech tool to program the controller, which adds a step and a cost. If you’d rather not deal with that, check with ECO first.

Key specs, explained

The seller estimates 40 to 45 miles per charge from the 105Ah pack, plenty for several rounds. Gen3 is ECO’s 2025 update, with better build quality, lower running temperatures at speed, a new wake-up button and app firmware updates. The listing promotes Gen3 but doesn’t label this exact bundle, so confirm the generation when you order.

How it compares

The ALLIED Big Box RS 48V 105Ah Lithium Golf Cart Battery Kit costs slightly less and includes a 15A charger too, but the 110V receptacle and a wake-up button aren’t in its box. The MODZ Slim 48V 105Ah Lithium Golf Cart Battery Kit (Heated) is heated as standard, has a 20A onboard charger and connects to the Allied Battery app. ECO is the pick for the fullest install kit.

Good to know

The seller strongly recommends a voltage reducer if you run 12V accessories, and it costs extra. The heated version warms cells below 32°F and costs extra too. Golf Cart Tire Supply says Gen3 bundles carry a lifetime warranty, but the listing doesn’t spell out the terms.

Questions about the ECO Battery 48V 105Ah Thru-Hole Lithium Golf Cart Battery Kit

Does it have a lifetime warranty?

The seller says Gen3 bundles do. Confirm that your kit is Gen3 and ask for the warranty terms in writing.

Do I need to lift the seat to turn it on?

No. The included wake-up button mounts on the dash, so you can turn the pack on with the seat down.
