48V vs 72V Lithium Golf Cart Battery: Understanding Your Options
When upgrading to lithium, the voltage of your lithium pack must match your cart's existing voltage system. You cannot put a 72V lithium pack in a 48V cart without also replacing the controller, charger, and motor. This guide compares the two options within their appropriate system contexts.
Quick Compatibility Check
| Your Current System | Compatible Lithium Pack | NOT Compatible |
|---|---|---|
| 36V cart | 36V lithium pack | 48V or 72V lithium |
| 48V cart | 48V lithium pack | 72V lithium |
| 72V cart | 72V lithium pack | 48V lithium |
48V Lithium Pack: What to Expect
| Spec | Typical 48V LiFePO₄ Pack |
|---|---|
| True pack voltage | 51.2V nominal (58.4V charged) |
| Capacity | 100–200 Ah |
| Estimated range | 45–90 miles |
| Weight | 90–120 lbs (vs. 280–320 lbs for AGM) |
| Installed cost | $1,995–$3,395 |
| Lifespan | 10+ years / 3,000–5,000 cycles |
72V Lithium Pack: What to Expect
| Spec | Typical 72V LiFePO₄ Pack |
|---|---|
| True pack voltage | 76.8V nominal (87.6V charged) |
| Capacity | 100–160 Ah |
| Estimated range | 50–90 miles |
| Weight | 110–145 lbs |
| Installed cost | $3,395–$3,795 |
| Lifespan | 10+ years / 3,000–5,000 cycles |
Range Comparison at Same Capacity
At the same amp-hour (Ah) rating, a 72V pack stores more total energy than a 48V pack (Energy = Voltage × Ah). A 72V 100Ah pack stores 7,200 Wh vs. a 48V 100Ah pack at 4,800 Wh — 50% more energy.
This is why 72V carts can achieve longer absolute ranges even at equivalent Ah ratings.
