Li-Po battery voltage chart
Essential LiPo Battery Voltage Guide
The performance and longevity of your LiPo battery depend on maintaining optimal voltage levels throughout its lifecycle. Here’s a quick rundown of the key voltage points you need to know:
- Full Charge Voltage: The maximum voltage at which a fully charged LiPo cell operates, typically around 4.2V per cell.
- Nominal Voltage: The average operating voltage of a LiPo cell when it’s partially charged, usually about 3.7V to 3.8V.
- Cut-off Voltage: The minimum safe voltage at which the battery should not be discharged further to avoid damage and reduce lifespan, typically around 2.75V per cell.
Quick Reference LiPo Battery Voltages
To help you quickly identify the voltage levels of your LiPo batteries, here’s a handy reference chart:
| Number of Cells (S) | Full Charge Voltage (V) | Nominal Voltage (V) | Cut-off Voltage (V) |
|---|---|---|---|
| 1 | 4.20 | 3.70-3.80 | 2.75 |
| 2 | 8.40 | 7.40-7.60 | 5.50 |
| 3 | 12.60 | 11.10-11.40 | 8.25 |
| 4 | 16.80 | 14.80-15.20 | 11.00 |
| 5 | 21.00 | 19.30-19.60 | 13.75 |
| 6 | 25.20 | 23.80-24.00 | 16.50 |
LiPo Battery Voltage Levels Demystified
The voltage of a LiPo battery changes as it charges and discharges, impacting its performance and lifespan. Understanding these fluctuations is crucial:
- Charging Phase: During charging, the voltage increases gradually until reaching full charge.
- Discharging Phase: As you use your device, the battery discharges, causing the voltage to drop. It’s important not to let it fall below the cut-off voltage.
LiPo Battery Safe Voltage Range
Maintaining a LiPo battery within its safe voltage range is essential for optimal performance and longevity:
- Safe Operating Range: 3.0V to 4.2V per cell.
- Avoid Overcharging: Charging beyond the full charge voltage can damage cells and reduce battery life.
- Avoid Deep Discharge: Discharging below the cut-off voltage can cause irreversible damage and shorten lifespan.
LiPo Battery Discharge Voltage Chart
The following chart illustrates how the discharge voltage changes with usage for a typical LiPo battery:
| Usage Percentage (%) | Voltage (V) |
|---|---|
| 0-25% | 3.70-4.00 |
| 26-50% | 3.50-3.80 |
| 51-75% | 3.30-3.60 |
| 76-100% | 2.80-3.40 |
LiPo Battery Charging Voltage Guide
To ensure your LiPo battery charges safely and efficiently, follow these guidelines:
- Use a Proper Charger: Invest in a quality charger designed specifically for LiPo batteries.
- Select the Correct Settings: Set the charger to match the number of cells in your battery pack.
- Avoid Overcharging: Never leave a charging LiPo battery unattended, as overcharging can lead to overheating and potential fire hazards.
Understanding LiPo Battery Voltage Drops
Voltage drops during discharge are normal but should be monitored carefully. Here’s what you need to know:
- Sudden Voltage Drop: Indicates a malfunction or over-discharge, which can damage the battery.
- Gradual Voltage Decrease: Normal during use; monitor closely and recharge before reaching cut-off voltage.
