Echo lithium battery upgrade
"The new ECO Battery is just flawless. The problem is with the 2016 easy go RXV, the instructions/youtube videos for the metal replacement tray is just nonexistent. Other than that, I love the install."

Eco Battery 48V 105Ah Skinny Bundle Kit (And What's Included)
Not every 48V golf cart battery tray is shaped the same. Some carts need a longer, narrower lithium battery layout to fit correctly, and that is exactly what the Eco Battery 48V 105Ah Skinny Bundle Kit is built for.
If your cart uses that style of tray, this lithium battery bundle gives you a more complete path into lithium without having to sort out every charger, bracket, charge-port part, and support component on your own. Instead of trying to build the setup one piece at a time, you can choose the fitment that matches your cart and get a bundle built around that application.
This is a strong option if you are replacing lead-acid batteries and want a setup that is cleaner, more capable, and easier to live with long term. It also makes sense if your cart already has upgraded motors and controllers and you need a lithium battery bundle that can keep up.
It is also backed by a Limited Lifetime Warranty with 6 years of full replacement, which is one of the biggest reasons many golf cart owners choose Eco Battery when stepping up to lithium.
If you are still comparing lithium upgrade options, our Good, Better, Best Guide is a smart place to start before choosing the bundle that fits your cart best.
A lot of the value here comes from getting the right battery shape for the right cart. The Skinny bundle is designed for supported applications that do not use the grouped tray layout associated with the Thru-Hole version. That difference can affect:
- mounting hardware
- charge-port components
- display and meter parts
- CAN-related accessories
Because of that, included parts vary by fitment. This is not a universal lithium battery bundle. It is a cart-specific bundle built around the supported application you select.
Why Customers Choose the 48V 105Ah Skinny Bundle
For the right cart, the Skinny bundle solves a fitment problem first and a battery problem second. That matters because even a strong battery is the wrong choice if the layout does not match the tray design in your cart.
This bundle also gives you the features most customers want from a premium lithium setup:
- Bluetooth
- CAN capability
- mobile app compatibility
- over-the-air software updates
It is built for real golf cart use with LiFePO4 chemistry, prismatic cells, IP67-rated protection, charging freeze protection under 32F, and a powder-coated steel shell. On the output side, it delivers 250A max continuous discharge, 600A max discharge for 5 seconds, and 550A max discharge for 10 seconds. If performance is part of the bigger plan, you can also browse our Golf Cart Performance Upgrades to see what pairs well with a lithium setup like this.
What You Can Expect from the Upgrade
One of the biggest differences most customers notice when moving from lead acid to lithium is how much more consistent the cart feels throughout the ride. You are not dealing with the same drop-off in performance that often shows up as older batteries drain down. The cart feels steadier, more responsive, and easier to rely on.
Expected range is roughly 20–45 miles per charge, depending on:
- Cart setup
- Terrain
- Tire size
- Payload
- Driving style
- Overall efficiency
If your goal is a more complete electrical build, this battery bundle also works naturally with larger upgrades. You can pair your lithium setup with an EB Power AC Conversion Kit or explore more Golf Cart AC Conversion Kits if you are building for stronger acceleration, better efficiency, and a more complete performance setup.
Heated Battery Option
If you ride or charge your cart in colder weather, the heated battery option is worth considering.
The main purpose of the heated battery is to help allow charging in below-32°F weather. Standard lithium batteries should not be charged when battery temperature drops below freezing. Choosing the heated version helps protect the battery in colder conditions and gives you a better option for winter charging.
This is especially helpful if your cart is stored or charged in:
- Unheated garages
- Sheds
- Barns
- Colder seasonal climates
If your cart stays in a climate-controlled space year-round, you may not need the heated option. But if there is a good chance your battery will be charged in freezing or near-freezing temperatures, it is a smart upgrade to consider.
Supported Fitments
The Eco Battery 48V 105Ah Skinny Bundle Kit is offered for supported 48V electric carts shown in the dropdown. Common applications include:
- EZGO TXT and Express
- EZGO RXV (metal battery tray; typically has 6 x 8v batteries)
- Club Car DS H-Frame
- Club Car Carryall 2015+
- Yamaha G19-G22
- Navitas chassis
- Pilot Car
- Polaris Ranger
- Epic EV with 3x3 battery tray
- Epic EV with 4x2 factory battery tray
- Advanced EV
This bundle is best suited for:
- Supported 48V electric carts
- Carts replacing a lead-acid setup
- Stock carts
- Carts with upgraded motors and controllers
- Carts that need the narrower Skinny battery layout
This bundle does not fit carts with a factory lithium battery.
If you are still sorting out which lithium battery bundle makes the most sense for your cart, the Lithium Knowledge Center is a good next stop for deeper battery education and fitment guidance.
Skinny Bundle vs Thru-Hole Bundle
The easiest way to think about it is tray shape.
The Skinny bundle is generally the better choice when your cart uses a longer, narrower tray layout. The Thru-Hole bundle is generally the better fit when your cart uses the more grouped tray layout that battery style was designed around.
A common example is the EZGO RXV:
- RXV with factory metal tray (typically has 6 x 8v batteries) = Skinny bundle
- RXV with factory plastic tray (typically has 4 x 12v batteries) = Thru-Hole bundle
If your cart is listed in the supported fitments for the Skinny bundle, that is usually the right direction. If your cart is not listed here, you will most likely need the Eco Battery 48V 105Ah Thru-Hole Bundle Kit instead. If you j need the battery without the charger, check the 48V 105Ah GEN3 Eco Skinny Battery Individual.
A Few Things to Confirm Before Ordering
Before ordering, make sure your cart appears in the dropdown fitment and that your cart is electric rather than factory lithium.
It is also worth confirming a few application details where relevant:
- RXV tray type
- Club Car DS frame style
- Year and application details for Yamaha, Epic EV, Advanced EV, and similar carts that the selected bundle includes the support parts you expect for your setup
A few install notes matter as well:
- Many fitments show the 51V to 12V DC-DC converter as optional if you do not already have one
- If the selected bundle includes a CAN-enabled charger, CAN must be connected for charging to work correctly
- The battery must be powered on with the illuminated power button to accept a charge
- Some applications may require additional cart-specific setup details, such as Pilot Car programming support
FAQ
What is the Eco Battery 48V 105Ah Skinny Bundle Kit?
It is a fitment-based 48V lithium battery bundle for supported electric golf carts. It is built around the Eco Battery Skinny battery and includes cart-specific support parts depending on the fitment selected.
Who usually needs the Skinny bundle instead of the Thru-Hole bundle?
The Skinny bundle is usually the better fit for carts that use a longer, narrower battery tray layout. The Thru-Hole bundle is generally used for carts with the more grouped tray design. RXV carts are a common example, since metal-tray RXVs use the Skinny bundle while plastic-tray RXVs use the Thru-Hole version.
Is this a battery-only listing or a full lithium battery bundle?
This is a lithium battery bundle, not just a battery-only listing. The battery is the main component, but included parts change by fitment.
Will this work if your cart already has upgraded motors and controllers?
Yes. This bundle works with both stock carts and carts running upgraded motors and controllers.
Can you use this on a cart that came with factory lithium?
No. This bundle does not fit carts with a factory lithium battery.
Do all supported carts get the same included parts?
No. Included components vary by selected fitment, which is why it is important to review the bundle details for your application before ordering.
What battery features come with the 48V 105Ah Skinny setup?
The battery includes Bluetooth, CAN capability, mobile app compatibility, over-the-air software updates, LiFePO4 chemistry, IP67-rated protection, and charging freeze protection under 32F.
Can the 48V 105Ah Skinny battery be connected in parallel?
Yes. It can be connected in parallel up to 2 batteries. It is not series connectable.
How much range can you expect per charge?
Expected range is roughly 20–45 miles per charge, depending on your cart, terrain, tire size, payload, driving style, and overall efficiency.
What is the heated battery option for?
The heated battery option is designed to help allow charging in below-32°F weather. That makes it a smart upgrade for carts stored or charged in unheated garages, sheds, barns, or colder seasonal climates.
Do you need the heated battery option?
If your cart is charged in freezing or near-freezing temperatures, the heated option is worth considering. If your cart stays in a climate-controlled space year-round, you may not need it.
