Frequently Asked Questions
What is the maximum continuous discharge current for this battery?
The OID1072170LP22AH supports a continuous discharge current of 7C, which is equivalent to 154A. For short pulses up to 3 seconds, it can handle up to 10C (220A).
What is the recommended charging method?
Standard charge is 0.5C CC/CV to 4.2V with a cut-off current of 0.05C at 25°C. Fast charge at 1C and super-fast charge at 2C are also supported under the same termination conditions.
What is the operating temperature range?
Charging: 0°C to 45°C. Discharging: -20°C to 60°C. For optimal performance and cycle life, we recommend operating within 10°C to 45°C.
How should I store the battery for long periods?
Store at 0°C~35°C with humidity ≤75% RH. Maintain voltage between 3.75V~3.9V (40%-50% SOC). It is recommended to activate the battery every 3 months by charging to full at 0.2C, discharging to 2.8V, then charging back to 3.9V.
Is this battery safe for high-power applications like drones or e-mobility?
Yes. With a 7C continuous discharge and 10C peak, this high-drain Li-Polymer cell is designed for high-power applications including drones, RC models, and portable power tools. Always ensure your device's BMS is compatible with the battery's specifications.
What certifications does this battery hold?
The battery meets standard safety and performance criteria as per the product specification. For specific certification needs (e.g., UN38.3, MSDS), please contact our sales team at alan@liion-batt.com.
What is the warranty period?
Jianheng provides a 12-month warranty from the date of shipment, covering manufacturing defects under proper usage conditions as outlined in the specification. The warranty does not cover misuse, improper assembly, or use outside specified parameters.
What should I do if the battery shows swelling or deformation?
Immediately stop use and isolate the battery from flammable materials. Do not attempt to charge or discharge it. Contact Jianheng technical support for proper disposal or replacement guidance.
Storage and Shipment
Shipping voltage: 3.5V ~ 3.6V. Long-term storage should maintain voltage between 3.7V and 3.9V. Prolonged storage above 3.9V (over 7 days) is strictly prohibited to ensure safety and longevity.
Mechanical Reliability
The battery passes rigorous vibration and drop tests: no fire, no explosion, and no leakage after vibration (10Hz~55Hz, amplitude 1.6mm, 30 min per XYZ axis) or free drop from 1.2m onto a wooden board.
Safety Precautions
Dangers: Do not expose to fire, puncture, disassemble, or mix with incompatible cells.
Warnings: Use only designated Li-Polymer chargers, avoid humid environments during charging, and stop use immediately if swelling or leakage occurs.
Precautions: Charge fully before first use, ensure ventilation during charging, store in cool dry places, and avoid excessive cycle frequency.
