Converting golf cart batteries to lithium typically costs between $1,800 and $5,500, depending on battery capacity, voltage, and brand. For example, a 48V 30Ah lithium iron phosphate (LiFePO4) pack starts around $1,300, while higher-capacity 48V 105Ah systems reach $3,000. Installation fees add $200–$500 for labor, wiring, and controller adjustments. Pro Tip: Always verify charger compatibility—lithium-specific chargers (e.g., 48V/72V CC-CV models) cost $200–$600 extra but prevent overcharging risks.

What factors influence lithium conversion costs?
Battery capacity, voltage, and brand quality drive price variations. Higher Ah ratings extend range but increase costs by 40–60% per 30Ah increment. Premium brands with UL-certified BMS systems cost 20–35% more than generic alternatives but offer longer warranties.
Lithium batteries require tailored voltage configurations. A 48V system with 100Ah capacity delivers ~5kWh, sufficient for 25–35 miles per charge. However, upgrading to 72V for torque-heavy terrains raises costs by $800–$1,200 due to additional cells and reinforced wiring. For example, a Club Car DS with 72V 80Ah lithium batteries costs $4,200–$4,800 installed, versus $3,000–$3,500 for a 48V setup. Pro Tip: Prioritize batteries with low-temperature cutoffs if operating in sub-freezing climates to prevent capacity loss.
How do installation costs break down?
Professional installation includes labor ($75–$150/hour), wiring upgrades ($50–$200), and controller reprogramming ($100–$250). Technicians typically spend 2–4 hours removing lead-acid batteries, installing mounting trays, and testing voltage stability.
For DIYers, lithium conversion kits with pre-assembled racks and connectors cost $150–$300. However, improper BMS calibration risks reducing cycle life by 30–50%. A real-world example: Retrofitting a Yamaha G29 with a 48V 60Ah lithium pack requires bypassing the onboard computer’s voltage checks—a task best left to certified EV technicians. Practically speaking, paying for professional installation ensures warranty validity and avoids costly errors like reversed polarity connections.
| Component | Cost Range | Notes |
|---|---|---|
| Battery Pack | $1,300–$4,000 | 48V–72V, 30–150Ah |
| Charger | $200–$600 | Lithium-specific CC-CV required |

FAQs
No—lead-acid chargers lack voltage precision, risking overcharge. Use only lithium-certified chargers with ±1% voltage tolerance.
Do lithium batteries fit standard golf cart battery trays?
Most LiFePO4 packs come in GC2 sizes but verify dimensions—some require tray modifications or spacers.
