MODZ Slim 48V 105Ah Lithium Golf Cart Battery Kit (Heated)

The MODZ Slim 48V 105Ah Lithium Golf Cart Battery Kit (Heated) adds a built-in heater and a 20A onboard charger to a slim LiFePO4 pack sized for the factory tray.

Why it made the list

Lithium cells shouldn’t be charged below freezing, so an unheated pack in a cold garage can refuse to charge on a winter morning. A heated pack fixes that by warming its own cells. MODZ builds the heater into this kit as standard, which makes it the one to buy for cold climates.

It also brings the fastest charger among the brand-name kits on our list: the MODZ onboard speed charger, rated at 20 amps and 1200 watts. That’s faster than the 15A chargers in the ALLIED and ECO kits, so you get back on the course sooner.

What it does well

• The pack delivers 250A continuous and 550A peak for 10 seconds, plenty for hills and lifted carts.
• An IP67 rating means the pack is sealed against dust and short immersion.
• An LCD meter shows state of charge and doubles as the wake-up button.
• The listing says it connects to the Allied Battery app over Bluetooth on iPhone or Android.

The kit also includes a 16 ft high-visibility extension cord, a 40-inch 2-AWG heavy-duty power cable set and a hardware packet with 4-gauge cables.

Who it’s for

This is for owners in northern climates who store the cart in an unheated garage or play into late fall. The seller also recommends it for modified 2- and 4-seat carts, lifted carts and controllers up to 450A.

Who should skip it

If you own a 2004 to 2008 Precedent, this won’t fit; the seller points those owners to the NANO version. In warm climates, you’re paying for a heater you won’t use.

Key specs, explained

The pack is 51.2V nominal in a 1P16S layout, meaning 16 cells in series, the standard build for a 48V lithium pack. It stores 5.38 kWh, and the seller estimates 30 to 45 miles per charge. The 20A onboard charger mounts in the cart, so you just plug in the cord.

How it compares

The ECO Battery 48V 105Ah Thru-Hole Lithium Golf Cart Battery Kit costs less and its heated version is an add-on, with a 15A charger and a dash wake-up button. The BOLT Energy 48V 105Ah Lithium Golf Cart Battery Standard Kit has a 12-year fixed warranty and a powder-coated steel case. MODZ is the pick for cold weather and fast charging.

Good to know

The E-Z-GO RXV needs an alternative mounting bracket, with either the plastic or metal tray. Yamaha Drive, Drive-2 and G29 carts may need slight modification, and Navitas carts may need trimming. The seller lists a lifetime warranty but doesn’t publish the terms on the page, so ask for them before you buy.

Can I charge in the cold?

Yes, that’s what the heater is for. The pack warms its cells so it can take a charge in freezing weather.

Does it fit my Club Car?

It fits the Onward, Tempo, Villager, DS and 2008 and newer Precedent. The 2004 to 2008 Precedent needs the NANO version.
