Battery Safety Information

LiPo Battery Safety & Handling Guide

At Nihewo and Youme Power, your safety is our top priority. Lithium Polymer (LiPo) batteries provide high-performance power but require strict adherence to safety protocols to prevent fire, injury, or property damage.

⚠️ WARNING: READ BEFORE USE

By purchasing and using Nihewo or Youme Power products, the user assumes all risks associated with LiPo batteries. We are not responsible for any damage or injury caused by misuse.

1. Charging Safely

  • Use LiPo-Specific Chargers: NEVER use a NiCd/NiMH charger. Only use a high-quality balance charger specifically designed for LiPo batteries.

  • Balance Charge: Always use the balance charging mode to ensure each cell remains at the same voltage.

  • Never Leave Unattended: Never leave a charging battery unattended. Always charge in a visible area.

  • Charge Rate: We recommend a charge rate of 1C (e.g., charge a 2200mAh battery at 2.2A) unless otherwise specified.

2. Storage & Transportation

  • Storage Voltage: For long-term storage (more than 2 days), keep batteries at a storage voltage of 3.80V - 3.85V per cell.

  • Fireproof Containers: Always store and transport batteries in a LiPo Safebag or a fireproof ammunition box.

  • Environment: Store in a cool, dry place ($5\text{°C} - 25\text{°C}$). Keep away from flammable materials and direct sunlight.

3. Usage & Discharge

  • Low Voltage Cutoff: Never discharge a cell below 3.2V under load (3.5V resting). Over-discharging will permanently damage the battery chemistry.

  • Temperature Limits: Stop usage if the battery temperature exceeds $60\text{°C}$ ($140\text{°F}$).

  • Inspect Before Use: Check for physical damage, swelling (puffing), or leaking. NEVER use or charge a "puffed" or damaged battery.

4. Proper Disposal

  • Do Not Trash: Never throw LiPo batteries in the regular trash.

  • Neutralize: Discharge the battery to 0V and recycle it at a local hazardous waste collection center or a dedicated battery recycling point.
