What a golf cart lithium conversion actually costs in 2026 — a complete buyer's breakdown: kit pricing, controller upgrades, model-by-model cost for E-Z-GO, Club Car & Yamaha, and the real 10-year math versus buying lead-acid again.

What a Lithium Conversion Costs (The Short Version)

The cost of converting a golf cart to lithium comes down to one main thing: the conversion kit. Across the market, a complete lithium conversion for a standard 48V cart generally lands between $1,500 and $3,000 when you install it yourself, and more if a shop does the work or you add performance parts.

Two things drive the number more than anything else: voltage (36V, 48V, or 72V, set by your cart) and capacity (the amp-hour rating, which decides range and headroom under load). A bare battery is only part of a working conversion — a complete kit also includes a lithium-compatible charger, mounting hardware, a charge meter, and cables.

With Bedrock, kit pricing currently ranges from $1,549 for the 48V 65Ah system to $2,849 for the 72V 105Ah system. Because each kit is the whole conversion — not a bare battery you build on — that price is what it costs to get the cart running, which keeps both the cost and the install predictable.

What's Included in the Price — and What Isn't

A common reason lithium conversion quotes vary so much from one brand to another is that they aren't always quoting the same thing. Some prices are for a battery only. A complete kit price covers the full system needed to get the cart running.

A complete conversion kit should include:

• 🔋
  The lithium battery system A purpose-built LiFePO4 pack with a robust battery management system (BMS), rated for sustained golf cart demand — not a generic drop-in cell.
• 🔌
  A lithium-compatible charger and charging port Lead-acid chargers can't safely charge lithium, so this is required, not optional. A complete kit includes a universal adapter so compatibility is solved up front.
• 🔩
  Cart-specific mounting hardware The brackets and hardware to secure the system cleanly in your cart's battery bay, so fitment is built in rather than improvised.
• 📟
  A charge meter So you can read state of charge at a glance, the same way you'd expect from a finished, dependable install.

What's usually not in the base price: optional model-specific adapters or brackets, professional installation labor, and any performance controller upgrade (covered below). Those adjust the final number above the base kit cost.

Cost by Golf Cart Model: E-Z-GO, Club Car & Yamaha

Your cart's make, model, and year decide your stock voltage — and voltage is the biggest single cost driver. Here's how the most common platforms break down. Always confirm your year from the serial number or build-date sticker before buying, because several models span both 36V and 48V.

A few model-specific notes that affect cost:

• ⚡
  E-Z-GO TXT splits at 2010 36V before, 48V after. A 36V TXT often runs better on a 48V conversion — but that's a voltage increase, which means a new charger and usually a controller change (see below). Budget accordingly.
• ⚡
  Club Car DS is the trap Pre-1995 cars are 36V, 1995+ are 48V, and both are still common. Confirm the year from the serial number before ordering.
• ⚡
  Yamaha uses a proprietary charge port It varies by year. A complete kit handles the charging side, but verify the plug for your model.

Conversion Kit Pricing by Voltage and Capacity

Here is the current Bedrock lineup with starting prices. Your cart's existing voltage decides which row you're in; capacity (the Ah rating) is where you match the system to your terrain, passenger load, and any upgrades.

If you're unsure which row fits your cart, the lead-acid to lithium conversion checklist walks through confirming voltage, fitment, and the right capacity before you buy. You can also see the full range on the golf cart lithium conversion kits page.

Do You Need a Controller Upgrade? ($300–$1,200)

This is the cost most "all-inclusive" pages leave out — so here's the straight answer.

For a like-for-like lithium swap at the same voltage, you usually do not need a controller upgrade. Drop a 48V lithium pack into a 48V cart and the existing controller keeps working as designed. The one required electrical change is a lithium-compatible charger — which a complete kit already includes.

You would budget for a controller upgrade if you're chasing more speed or power, or stepping up voltage (for example, converting a 36V cart to 48V). In that case:

• 🔧
  A standalone upgraded controller Runs roughly $200–$600 depending on amperage and brand.
• 🏎️
  A full performance package Controller plus motor or a matched speed kit can run $1,200–$1,700+.

The 5 Factors That Change Your Cost

Two owners can pay different amounts for a conversion, and the reasons are predictable. These are the five things that move the number.

• 1
  Voltage (36V, 48V, or 72V) Your cart's existing system sets this. Higher-voltage systems generally cost more because they're built for more demanding carts and electrical setups.
• 2
  Capacity (the Ah rating) More amp-hours means more range and more headroom under load — and a higher price. Stepping from a 105Ah to a 150Ah system is the most common reason a 48V conversion costs more.
• 3
  Your cart model and fitment Some carts need a model-specific bracket or adapter for a clean install. These are minor relative to the kit, but they're why two 48V quotes aren't always identical.
• 4
  Performance upgrades A high-output controller, larger tires, a lift, or a rear seat all increase electrical demand — and may add controller or charger costs. Carts like these are better matched to a higher-capacity system.
• 5
  Complete kit vs. battery-only A full kit is the all-in conversion price. If you already run a lithium system and only need a battery to add in parallel, an individual battery costs less — but it isn't a standalone conversion.

DIY vs. Professional Install: The Labor Question

Labor is the part of "total cost" that varies the most between owners — because for many DIY conversions, there isn't any.

Complete kits are designed for DIY installation. Each ships with cart-specific mounting hardware, onboard charging components, and a step-by-step installation manual written specifically for golf cart conversions. For a stock cart, most owners complete the install themselves with common hand tools, which means the kit price is effectively the full cost of the conversion.

Lithium vs. Lead-Acid: The Real 10-Year Cost

The honest comparison isn't the price on day one — it's the cost over the life of the cart. Lead-acid costs less up front, but you buy it more than once. Here's a representative 10-year picture for a 48V cart installed DIY (so labor is $0 on both sides):

Hidden Costs to Watch for With Cheaper Batteries

Lithium golf cart batteries are easier to buy than ever, and some listings are priced to look like an obvious saving. The lower number is real — but it often doesn't represent the full cost of a working, lasting conversion.

Beyond the parts you have to add, the costs that tend to surface later are the ones worth planning around:

• ⚠️
  An undersized BMS A battery management system not built for sustained golf cart demand can cut off on hills or under a full load, and chronic stress shortens its usable life — which can mean replacing it sooner than planned.
• ⚠️
  Unclear or hard-to-use warranty A vague warranty can leave you covering the cost of an early failure yourself. Clear, structured coverage is part of what you're paying for — see exactly how Bedrock's works below.
• ⚠️
  Support that doesn't know golf carts When questions come up after install, general or seller-based support can mean slower answers — and time spent troubleshooting is its own kind of cost.

None of this makes a lower-cost battery impossible to live with. It just means the cheapest listing and the lowest true cost of a dependable conversion aren't always the same thing. For a fuller comparison, see Bedrock Battery vs. Amazon lithium brands.

What the Warranty Actually Covers (The Fine Print)

Warranty is part of the price you pay — and it's where cheap batteries often hide their real cost. Here's exactly how Bedrock's coverage works, in plain terms, so you can compare it line-for-line against any other brand:

• 📅
  Length: 10 years From the original date of purchase.
• 📝
  Registration matters Register within 90 days for the full 10-year coverage. Register between 90 and 365 days and coverage drops to 5 years. Not registered within 365 days = no coverage. Set a reminder the day your kit arrives.
• ✅
  Free-replacement window: months 0–60 The first 5 years are free replacement or repair, at Bedrock's discretion.
• 📉
  Prorated after year 5 Replacement is available at a share of MSRP — 55% (months 61–72), 65% (73–84), 75% (85–96), 85% (97–120). Coverage continues the full decade, but your share rises over time.
• 🔄
  Transferable once: $100 fee You can transfer the warranty to a new owner one time within 3 years of purchase. Coverage continues from the original date and doesn't reset — a real resale advantage.
• 📦
  Claim basics Defect claims need an RMA; the customer prepays $300 for packaging/shipping within the U.S., and Bedrock covers return shipping.

How to Get the Right Kit for Your Budget

The goal isn't the lowest price — it's the right system at a fair price, sized correctly so you don't pay again later. A few practical guidelines:

• ✅
  Start from your voltage, then your terrain Voltage is fixed by your cart. From there, match capacity to how you actually use the cart — flat neighborhood loops need less than hilly, fully loaded runs.
• ✅
  Buy a little more capacity than you think you need A system running comfortably below its limit lasts longer and performs more consistently than one pushed to its ceiling every drive. It's the cheaper decision over ten years.
• ✅
  Compare complete kits, not bare batteries Make sure any price you weigh includes a charger, mounting, a meter, and cables — otherwise you're comparing two different purchases.
