2. Safety Precautions
Lithium Polymer (LiPo) batteries are powerful and require careful handling. Failure to follow these safety guidelines can result in fire, personal injury, and property damage.
- Charging: Always charge LiPo batteries on a fire-resistant surface and never leave them unattended during charging. Use only chargers compatible with LiPo batteries and ensure correct voltage and current settings. The G-Tech smart chip allows for automatic identification with G-Tech Imars Mini or Imars D300 chargers, but manual settings are required for regular chargers.
- Discharging: Do not over-discharge the battery. Stop using the battery if its voltage drops below 3.0V per cell (9.0V for a 3S battery). Over-discharging can permanently damage the battery.
- Physical Damage: Do not puncture, drop, or expose the battery to impact. If the battery is damaged, swollen, or leaking, discontinue use immediately and dispose of it safely.
- Temperature: Do not expose the battery to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F). Avoid direct sunlight and store in a cool, dry place.
- Short Circuit: Prevent short circuits by ensuring connectors are properly insulated and never allow battery terminals to touch each other or conductive materials.
- Disposal: Dispose of damaged or old LiPo batteries according to local regulations. Never dispose of LiPo batteries in regular trash.
3. Setup
3.1 Initial Inspection
Upon receiving your Gens ace G-Tech LiPo battery, inspect it for any signs of damage, swelling, or loose connections. If any issues are found, do not use the battery and contact customer support.
3.2 Charging the Battery
Before first use, fully charge the battery. Always use a compatible LiPo charger.
- Using G-Tech Smart Chargers (Imars Mini or Imars D300):
- Connect the XT60 main discharge plug and the G-Tech balancer connector to the charger.
- The G-Tech smart chip will automatically identify the battery type and initiate charging.
- Charging will automatically stop when the battery is fully charged.
- Using Regular LiPo Chargers:
- Connect the XT60 main discharge plug to the charger's output.
- Connect the G-Tech balancer connector to the charger's balance port.
- Manually set the charger parameters:
- Battery Type: LiPo
- Cell Count: 3S (11.1V)
- Charging Current: Typically 1C (2.2A for a 2200mAh battery). Do not exceed 2C (4.4A).
- Start the charging process and monitor the battery.

4. Operating Instructions
4.1 Connecting to Your RC Model
Ensure your RC model is compatible with an 11.1V (3S) LiPo battery and has an XT60 connector. Connect the battery's XT60 plug to the corresponding connector on your RC model. Ensure a secure connection.
4.2 Discharge Rate
This battery has a continuous discharge rate of 25C and a maximum burst discharge rate of 50C. Ensure your RC model's power requirements do not exceed these limits to prevent battery damage and ensure optimal performance.
4.3 Monitoring Battery Voltage
It is crucial to monitor the battery voltage during use. Do not allow the voltage to drop below 3.0V per cell (9.0V total for this 3S battery). Using a low voltage alarm or telemetry system in your RC model is highly recommended to prevent over-discharge.
5. Maintenance & Storage
5.1 Storage
For long-term storage, charge or discharge the battery to a storage voltage of 3.8V-3.85V per cell (11.4V-11.55V for a 3S battery). Store the battery in a cool, dry place, away from direct sunlight and flammable materials. A LiPo-safe bag is recommended for storage.
5.2 Regular Inspection
Periodically inspect the battery for any signs of physical damage, swelling, or connector wear. If any issues are observed, discontinue use.
5.3 Charging Cycles
LiPo batteries have a finite number of charge cycles. Proper charging and discharging practices will extend the battery's lifespan.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incorrect charger settings; faulty charger/cable; deeply discharged battery. | Verify charger settings (LiPo, 3S, correct current). Check connections. If deeply discharged, some chargers have a "storage" or "recovery" mode, but extreme caution is advised. |
| Battery swells during charging/use | Overcharging; over-discharging; physical damage; internal cell damage. | Immediately discontinue use and safely dispose of the battery. Swelling indicates a dangerous condition. |
| Short run time | Battery degradation; over-discharge; high current draw from model; cold weather. | Ensure battery is fully charged. Avoid over-discharging. Check model's power consumption. Operate in suitable temperatures. Consider battery replacement if degradation is suspected. |
| Battery gets hot during use | Excessive current draw; internal resistance increase; short circuit. | Reduce load on the battery. Check for short circuits in the model. If overheating persists, discontinue use and inspect the battery. |
