How much does a lithium golf cart conversion cost?
For most 48V carts: $640 to $3,699 for a complete kit with a charger (median $1,580 across the 17 kits we track), plus the parts kits often leave out. Every figure on this page comes from the brands' own sites and updates when their prices do.
The kit
| What you buy | Lowest | Median | Highest |
|---|---|---|---|
| 48V kit with charger (17) | $640 | $1,580 | $3,699 |
| 36V kit with charger (12) | $732 | $1,249 | $2,267 |
| 48V battery only (5) | $800 | $1,800 | $2,700 |
What moves the price: capacity (a 150Ah pack holds about 45% more than a 105Ah one), continuous current, warranty length, and what's in the box. Kits sold only on Amazon aren't included here, because we don't publish Amazon prices.
The parts people forget
- 12V converter, for lights, horn and USB: $75–$90 in our list. How to size one.
- Lithium charger, if the pack is sold without one: $140–$299. Chargers compared.
- Hold-down or bracket: $20–$40 for universal hardware; cart-specific brackets usually come with the kit.
- Charge plug for your receptacle: $26–$32.
- Battery monitor (shunt) for an accurate gauge: $80–$110.
- Installation, if you don't do it yourself: ask a local golf cart shop for a quote; brackets made for your cart make it quicker.
Lithium vs lead-acid over time
A replacement set of six 8V lead-acid batteries costs about $1,350 to $1,700 (for example a Trojan T-875 six-pack listed around $1,600–$1,680, a store-brand equivalent around $1,350). Battery sellers generally put flooded lead-acid life at 3 to 5 years with good maintenance (watering, equalizing, never running flat).
Lithium kits in our database carry warranties of 5 to 15 years, and brands rate LiFePO4 cells for thousands of cycles. So the comparison over ten years is roughly two or three lead-acid sets against one lithium kit — before counting water, terminal cleaning, and the 250 lb or so of weight lithium takes off the cart. If you'll sell the cart within two years or drive it a few times a season, a new lead-acid set can still be the cheaper choice.
Charging cost is small either way: a full charge of a 48V 105Ah pack (5.4 kWh) costs about $1.02 at 18¢ per kWh, allowing for charger losses. That's close to the US residential average: 18.2¢ per kWh from January to August 2026, according to the U.S. Energy Information Administration.
Getting the most for your money
- Buy the kit that fits your cart first; a cheaper pack that needs a new bracket or controller isn't cheaper. Find your cart.
- Compare complete kits, not battery prices: charger, converter and meter add up.
- Read the warranty where you buy — some brands give different terms on Amazon and on their own site.
- Size the pack to your longest trip with the battery size calculator instead of buying the biggest one.
