What Devices Are Compatible with the Tenergy 31034 Battery?
This battery powers drones, RC cars, LED lighting systems, portable medical devices, and DIY electronics. It’s compatible with Tenergy chargers and third-party chargers supporting 3S Li-Ion configurations. Always verify voltage and connector type (e.g., XT60, Deans) before use to ensure compatibility.
How to Safely Charge and Store the Tenergy 31034 Battery?
Use a balanced Li-Ion charger set to 11.1V and 7.8A. Avoid overcharging (max 12.6V) or discharging below 9V. Store at 40-60% charge in a dry, cool place (10–25°C). Never expose to temperatures above 60°C or puncture the casing. Regularly inspect for swelling or damage.
What Are Common Issues and Troubleshooting Tips?
Common issues include voltage imbalance, reduced capacity over time, and connector wear. Rebalance cells using a quality charger. If runtime drops below 70%, consider replacing the pack. For connectivity problems, replace damaged connectors. Always follow manufacturer guidelines for disposal.
How to Extend the Lifespan of the Tenergy 31034 Battery?
Avoid full discharges; recharge when 20–30% capacity remains. Store at partial charge, and never leave connected to devices when idle. Use a low-current charger for maintenance charging. Keep terminals clean and free of corrosion.
Temperature management is critical – operating or storing the battery in environments exceeding 35°C accelerates capacity degradation. For seasonal storage (e.g., winter), discharge to 50% and place in a moisture-proof container. Users should also avoid stacking heavy objects on the battery, as physical stress can damage internal cells. Periodic calibration (full discharge/recharge every 3 months) helps maintain accurate capacity readings.
