Important Safety Instructions and Warnings
Lithium Polymer (LiPo) batteries are volatile. Failure to read and follow these instructions can result in fire, personal injury, and property damage. By purchasing this battery, the buyer assumes all risks associated with its use.
- Always charge LiPo batteries in a fire-safe location, away from flammable materials.
- Never charge a damaged battery. Inspect the battery for any damage before each use.
- Use only a LiPo compatible charger with a balance function. Do not use NiMH/NiCd chargers.
- Do not overcharge or over-discharge the battery. The voltage should not exceed 4.2V per cell during charging or drop below 3.0V per cell during discharge. For this 2S (7.6V nominal) battery, the maximum charge voltage is 8.4V and minimum discharge voltage is 6.0V.
- Do not leave charging batteries unattended.
- Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures.
- Do not puncture, disassemble, short-circuit, or expose the battery to water or fire.
- Keep batteries out of reach of children.
- In case of swelling, discontinue use immediately and place the battery in a fire-safe container.

Setup and First Use
Before using your Gens ace LiPo battery, ensure it is fully charged and properly connected to your RC vehicle.
- Inspect the Battery: Visually inspect the battery for any signs of damage, swelling, or exposed wires. Do not use if damaged.
- Charge the Battery: Fully charge the battery using a compatible LiPo charger with a balance function. Refer to the "Charging Instructions" section for details.
- Connect to Vehicle: Connect the 5.0mm bullet connectors from the battery to your RC vehicle's Electronic Speed Controller (ESC). Ensure correct polarity (red to positive, black to negative).
- Secure the Battery: Securely mount the battery in your RC vehicle to prevent movement during operation, which could lead to damage or disconnection.

Note: The battery features 5.0mm bullet connectors for power output. A separate JST-XH plug is typically used for balancing during charging, though the product description primarily mentions 5.0mm bullet for the battery itself.
Operating Instructions
The Gens ace 2S Shorty Lipo Battery is designed for high-performance RC applications. Always monitor battery performance during use.
- Voltage Monitoring: Do not discharge the battery below 3.0V per cell (6.0V for this 2S battery). Over-discharging can permanently damage the battery. Use an ESC with a low-voltage cutoff feature.
- Temperature: Avoid operating the battery in extremely hot conditions. If the battery becomes excessively hot during use, allow it to cool down before recharging or further use.
- Compatibility: Ensure your RC vehicle's ESC and motor are compatible with a 2S LiPo battery and can handle the discharge rate.

Charging Instructions
Proper charging is critical for the safety and longevity of your LiPo battery.
- Use a LiPo Charger: Always use a charger specifically designed for Lithium Polymer batteries with a balance charging function.
- Balance Charging: Connect the main 5.0mm bullet connectors to the charger's output and the balance lead (if present, typically JST-XH) to the charger's balance port. Balance charging ensures each cell charges to the same voltage, which is vital for battery health.
- Charge Rate: Do not exceed a 1C charge rate for standard charging (6.0A for a 6000mAh battery). Some advanced chargers and batteries may support higher rates, but always refer to the charger's manual and battery specifications.
- Monitor Charging: Never leave a charging battery unattended. Monitor the battery's temperature and voltage throughout the charging process.
- Full Charge Voltage: A fully charged 2S LiPo battery will reach 8.4V (4.2V per cell). The charger should automatically stop when this voltage is reached.
Warning: This battery does not come with charging wires or balance leads. These must be purchased separately and be compatible with your charger and the battery's 5.0mm bullet connectors and balance port (if applicable).
Maintenance and Storage
- Storage Voltage: For long-term storage, charge or discharge the battery to its storage voltage, typically 3.8V per cell (7.6V for a 2S battery). Most LiPo chargers have a "storage" mode.
- Storage Conditions: Store the battery in a cool, dry place, ideally in a LiPo-safe bag or container, away from direct sunlight, heat sources, and flammable materials.
- Regular Inspection: Periodically inspect the battery for any physical damage, swelling, or changes in performance.
- Disposal: Dispose of damaged or old LiPo batteries responsibly at a designated battery recycling facility. Never dispose of them in household waste or by incineration.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incorrect charger settings; damaged battery/charger; poor connection. | Verify charger settings for LiPo 2S; check all connections; inspect battery for damage. |
| Battery swells during charging/use | Overcharging; over-discharging; physical damage; internal short. | Immediately discontinue use and place in a fire-safe container. Do not attempt to use or charge. Dispose of safely. |
| Short run time | Battery not fully charged; aging battery; high discharge rate application. | Ensure full balance charge; consider battery age; verify application demands. |
| Battery gets hot during use | Excessive current draw; poor ventilation; internal resistance. | Reduce load on battery; ensure adequate cooling; inspect for damage. |
