# LiPo Battery Storage and Maintenance: Best Practices for Longevity
Proper LiPo (Lithium Polymer) battery storage is critical for maximizing lifespan, safety, and performance of your FPV drone. A poorly stored battery can lose capacity, swell, or even become a fire hazard. This guide explains the science behind LiPo storage and provides actionable steps to keep your batteries in peak condition.
## Why Storage Voltage Matters
LiPo batteries chemically degrade when stored at full charge (4.2V per cell) or deep discharge (below 3.0V per cell). The ideal storage voltage is **3.8V–3.85V per cell**, which minimizes electrolyte decomposition and internal resistance buildup.
| Cell Count | Storage Voltage Range | Recommended Storage Voltage |
|————|———————–|—————————–|
| 1S | 3.8V – 3.85V | 3.82V |
| 2S | 7.6V – 7.7V | 7.64V |
| 4S | 15.2V – 15.4V | 15.28V |
| 6S | 22.8V – 23.1V | 22.92V |
Most modern smart chargers have a “Storage” mode that automatically charges or discharges each cell to the target voltage.
## Temperature and Environment
* **Temperature:** Store LiPos in a cool, dry place (10–25°C). Avoid temperatures below 0°C (freezing) or above 40°C (hot car).
* **Humidity:** Keep batteries away from moisture to prevent corrosion of terminals.
* **Containment:** Use a fire‑proof LiPo safety bag or metal ammo can for added safety.
## Step‑by‑Step Storage Procedure
1. **Fly/Discharge** until each cell is around 3.5–3.7V (never below 3.0V).
2. **Connect** the battery to a charger with a Storage program.
3. **Select Storage Mode** – the charger will either charge or discharge to reach ~3.8V per cell.
4. **Monitor** the process; ensure balance leads are connected for multi‑cell packs.
5. **Remove** the battery and place it in a fire‑proof container.
6. **Store** in a cool, dry location away from flammable materials.
## Common Mistakes to Avoid
* **Leaving batteries fully charged** for more than 24 hours.
* **Storing in a hot environment** (car, attic, direct sunlight).
* **Stacking or crushing** packs, which can damage cells.
* **Ignoring puffy/swollen batteries** – retire them immediately.
* **Using damaged balance leads** – replace before storage.
