Need Help?

Our experts are here to help you find the lithium battery for your needs.

The Epoch 48V 105Ah MINI "Limax" series is a complete lithium golf cart battery conversion kit designed for carts like the Club Car DS, ICON Electric Vehicles, Bintelli, Epic EV, Vivid EV, and other 48-volt golf carts with compact battery compartments where a standard single-pack lithium battery does not fit. Built around LiFePO4 (Lithium Iron Phosphate) chemistry, it measures 15.8 inches long, 11.1 inches wide, and 10.9 inches tall.

This kit replaces your entire bank of 48-volt lead-acid batteries with one sealed, maintenance-free lithium unit. Everything needed for a complete conversion is included in the box.

What Is Included in the Complete Kit

Kit Contents

  • Complete Lithium Conversion Kit
  • 48V 15A Lithium Charger, Battery Gauge, 12V Converter Included
  • Cart Specific Mounting Brackets Included
  • Bluetooth App (iOS & Android)

Designed for Carts With Smaller Battery Compartments

The MINI form factor addresses a common installation problem. Many golf carts including the Club Car DS and newer low-speed vehicles like ICON, Bintelli, Epic EV, and Vivid EV have battery bays that are too compact for a full-size single-pack lithium battery. The MINI's reduced footprint fits these carts without requiring any modification to the battery compartment.

Compatible Cart Models Include:

  • Club Car DS
  • Club Car Precedent, Tempo, and Onward
  • ICON Electric Vehicles (i20, i40, i60, and related models)
  • Bintelli (Beyond, Sprint, and related models)
  • Epic EV
  • Vivid EV
  • Advanced EV
  • Evolution Golf Carts
  • EZGO TXT and EZGO RXV
  • Yamaha (most 48V models)

Before ordering, measure your battery compartment interior and confirm a minimum of 15.8 inches (L) by 11.1 inches (W) by 10.9 inches (H) of clearance is available. If you are unsure, contact us before purchasing.

Performance Compared to Lead-Acid

If your cart slows down on hills or loses power toward the end of a round, that is a lead-acid battery problem, not a cart problem. Lead-acid batteries lose voltage as they discharge, which means progressively less power from hole 1 to hole 18.

LiFePO4 chemistry maintains a stable voltage throughout the discharge cycle. Your cart performs the same whether the charge gauge reads 90% or 20% consistent acceleration, consistent hill performance, consistent power delivery to the end of the charge. The 200A continuous discharge rating supports normal golf cart use including hills and a full passenger load.

Estimated range is 30 to 50 miles per charge depending on terrain, passenger weight, speed, and accessory use. A standard 18-hole round of golf typically uses a portion of that capacity, leaving charge to spare for the drive home.

Maintenance-Free Operation

Unlike flooded lead-acid batteries, the Epoch MINI requires no water additions, no terminal cleaning, and no equalization charges. The case is sealed to IP67 standards, meaning it is rated waterproof to one meter for 30 minutes. There are no acid fumes and no venting requirements. The built-in Battery Management System (BMS) handles all protection functions automatically: overcharge, over-discharge, overcurrent, short circuit, and temperature limits.

Bluetooth Monitoring

The battery connects to the free Epoch app on iOS and Android via Bluetooth. The app displays real-time state of charge (percentage), voltage, current draw, and battery temperature. Over-the-air firmware updates for the BMS are supported through the app.

Charge Time and Charger Use

Using the included 48V 15A charger, a full charge from empty takes approximately 7 hours. The battery accepts partial charges without any negative effect on long-term capacity. Do not use your existing lead-acid charger it is not compatible with LiFePO4 chemistry and will damage the battery. Use only the included charger or a charger programmed specifically for LiFePO4 at the voltages listed in the technical specifications tab.

FAQs

Below are answers to the questions most frequently asked by customers considering this upgrade. If your question is not listed, contact us before purchasing.

Will this battery fit my Club Car DS?

Yes. The MINI form factor was specifically developed for the Club Car DS battery compartment, which is more compact than the battery bays in many other golf cart models. When selecting your cart at checkout, choose "Other" as your cart model not the Club Car Precedent or Tempo option, which uses a different bracket configuration.

Before ordering, confirm your compartment has at least 15.8 inches of length, 11.1 inches of width, and 10.9 inches of height of interior clearance. If you have any doubt, contact us with your compartment measurements before placing your order.

Will this battery fit my ICON, Bintelli, Vivid EV, or Epic EV golf cart?

Yes. The MINI form factor was designed for golf carts with compact battery bays including ICON Electric Vehicles, Bintelli, Vivid EV, Epic EV, and Advanced EV where a full-size single-pack lithium battery would not fit without modifying the battery compartment. If your cart model is not listed in the dropdown at checkout, select "Other."

Measure your battery compartment first and confirm a minimum of 15.8 inches (L) by 11.1 inches (W) by 10.9 inches (H) of interior clearance is available.

What makes the MINI different from the standard Epoch 48V 105Ah?

The MINI has a smaller physical footprint (15.8" L x 11.1" W x 10.9" H) compared to the standard 48V 105Ah, which is sized for larger battery bays found in traditional EZGO TXT and Yamaha carts. The MINI was designed specifically for golf carts that have compact or non-standard compartments such as the Club Car DS, ICON Electric Vehicles, Bintelli, Epic EV, and Vivid EV where the standard-size pack does not fit without modifying the battery compartment.

Both models share the same electrical specifications: 51.2V, 105Ah, 200A continuous discharge, and 3,500 cycle life.

How far will this battery take my golf cart on one charge?

Range varies based on several factors: terrain, passenger and cargo weight, driving speed, tire size, and accessory use (lights, radio, etc.). Under typical conditions on a stock 48V golf cart, you can expect 30 to 50 miles per charge. A standard 18-hole round of golf uses a fraction of that capacity for most players.

Carts that have been modified with larger tires, lifted suspension, performance motors, or heavy accessory loads will see lower range figures.

Can I use my existing lead-acid charger?

No. Lead-acid chargers are not compatible with LiFePO4 batteries. Using a lead-acid charger will damage the battery and will void the warranty. The complete kit includes a 48V 15A lithium charger that is matched to the LiFePO4 charging profile. Use only the included charger or a third-party charger that can be programmed to the exact voltage and current specifications listed in the Tech Specs tab.

How long does it take to fully charge?

Using the included 48V 15A charger, a full charge from empty takes approximately 7 hours. Partial charges are safe and do not negatively affect battery capacity or lifespan. LiFePO4 chemistry does not require full charge cycles.

Do I need a professional to install this, or can I do it myself?

Epoch recommends professional installation by a qualified golf cart technician. The kit includes step-by-step instructions, cart-specific mounting brackets, a pre-assembled wiring harness, a replacement charge receptacle, and an on/off switch for the dashboard. Customers who are comfortable with basic DC electrical work have completed the installation themselves, typically in 1 to 2 hours. Improper installation voids the warranty.

What about my 12V accessories  radio, lights, USB ports?

The kit includes a 48V to 12V DC converter specifically for this purpose. Connect all 12V accessories through the converter. Do not tap 12V accessories directly from the main battery terminals on a lithium system doing so can damage the battery and void the warranty.

Is this battery safe to store and charge in a closed garage?

Yes. LiFePO4 chemistry does not produce hydrogen gas or acid fumes. It does not require ventilation during charging. The sealed IP67-rated case prevents any liquid from escaping. The battery can be safely charged and stored in an enclosed garage. Recommended storage temperature is 32°F to 95°F (0°C to 35°C).

How does the 11-year warranty actually work?

The warranty is tiered:

  • Years 1 through 3: A defective battery is repaired or replaced at no cost to you.
  • Years 4 through 5: A comparable replacement is offered at 40% off the retail price at time of claim.
  • Years 6 through 11: A comparable replacement is offered at 25% off the retail price at time of claim.

You must register your battery at epochbatteries.com within 60 days of purchase to activate warranty coverage. Keep your proof of purchase. For Full details read the "Warranty" Tab.

Will switching to lithium make my cart faster?

On a stock, unmodified cart, the top speed will not increase. What you will notice is that the cart maintains consistent performance throughout the entire charge cycle. Lead-acid batteries lose voltage as they discharge, which causes the cart to slow down progressively. LiFePO4 maintains a stable voltage curve, so acceleration and hill performance remain consistent from full charge to near-empty.

Can I connect two of these batteries for more range?

Yes. The Epoch 48V 105Ah MINI supports a maximum of two units connected in parallel. This configuration doubles the capacity to 210Ah, roughly doubling the range. Both units must be identical (same model) and wired according to Epoch's parallel connection instructions. Do not connect more than two units in parallel.

How does this compare to replacing my lead-acid batteries again?

A quality set of 48V lead-acid batteries (for example, six 8V Trojan T-875s) typically costs between $800 and $1,200 and has a service life of 3 to 5 years under regular use, which means multiple replacements over a 10-year period. The Epoch MINI is rated for 3,500 cycles approximately 9 to 10 years of daily use with no water additions, no terminal maintenance, and no equalization charges. The upfront cost is higher; the long-term maintenance burden is significantly lower.

What is the difference between LiFePO4 and regular lithium batteries?

LiFePO4 (Lithium Iron Phosphate) is a specific type of lithium chemistry known for its thermal and chemical stability. Unlike lithium cobalt oxide cells used in some consumer electronics, LiFePO4 cells do not produce flammable gases under normal conditions and are not prone to thermal runaway. LiFePO4 also has a longer cycle life compared to other lithium chemistries.
