Golf Cart Voltage Chart
Use these reference charts to interpret multimeter readings on your golf cart battery pack. The numbers vary by battery chemistry (lead-acid/AGM vs. lithium) and state of charge. For instructions on how to take these readings, see our battery testing guide.
36-Volt System Voltage Chart (Lead-Acid / AGM)
| State | Pack Voltage | Per 6V Battery |
|---|---|---|
| Fully charged | 38.2 – 38.4V | ~6.37V each |
| 75% charged | 37.2 – 37.6V | ~6.2V each |
| 50% charged | 36.0 – 37.0V | ~6.0V each |
| 25% charged | 34.8 – 36.0V | ~5.8V each |
| Discharged (recharge now) | Below 34.8V | Below 5.8V each |
| Dead / over-discharged | Below 32V | Below 5.33V each |
| Under load (healthy) | Above 30V | Above 5.0V each |
48-Volt System Voltage Chart (Lead-Acid / AGM)
| State | Pack Voltage | Per 8V Battery (×6) | Per 12V Battery (×4) |
|---|---|---|---|
| Fully charged | 50.9 – 52.0V | ~8.5V each | ~12.75V each |
| 75% charged | 49.5 – 50.9V | ~8.25V each | ~12.4V each |
| 50% charged | 48.0 – 49.5V | ~8.0V each | ~12.0V each |
| 25% charged | 46.5 – 48.0V | ~7.75V each | ~11.6V each |
| Discharged (recharge now) | Below 46.5V | Below 7.75V each | Below 11.6V each |
| Dead / over-discharged | Below 44V | Below 7.33V each | Below 11.0V each |
| Under load (healthy) | Above 42V | Above 7.0V each | Above 10.5V each |
72-Volt System Voltage Chart (Lead-Acid / AGM)
| State | Pack Voltage | Per 12V Battery (×6) |
|---|---|---|
| Fully charged | 76.0 – 78.0V | ~12.75V each |
| 75% charged | 74.0 – 76.0V | ~12.33V each |
| 50% charged | 72.0 – 74.0V | ~12.0V each |
| 25% charged | 69.5 – 72.0V | ~11.6V each |
| Discharged (recharge now) | Below 69.5V | Below 11.6V each |
| Dead / over-discharged | Below 66V | Below 11.0V each |
| Under load (healthy) | Above 63V | Above 10.5V each |
Lithium (LiFePO₄) Voltage Chart
Lithium packs behave differently from lead-acid. Their resting voltage stays nearly flat across most of the usable range — you won't see much difference between 50% and 80% charge when the cart is at rest. The BMS (Battery Management System) handles the actual charge level tracking.
| System | Fully Charged (by charger) | Resting (nominal) | Discharged (BMS cutoff) |
|---|---|---|---|
| 48V lithium | 54.6V (16S pack) or 58.4V (16S LFP) | ~51.2V nominal | ~40–44V |
| 72V lithium | ~84V (24S NMC) or ~76.8V (24S LFP) | ~72V nominal | ~60–66V |
Note: Lithium packs labeled "48V" often charge to 54–58V and rest at ~51V. This is normal — the nominal 48V rating follows lead-acid convention. Our nominal vs. actual voltage guide explains this in detail.
How to Read Voltage Accurately
For accurate readings:
If your pack reads significantly below the "discharged" thresholds above, your batteries may have one or more failing cells. Bring the cart to any TIGON Golf Carts location for a free battery load test, or call 1-844-844-6638.
