Charging, Protection, and Safety

• Charge with a compatible LiPo charger at the recommended charge current (typically 0.5C to 1C). For this 800mAh cell, safe charging currents are commonly 400mA to 800mA depending on the charger and PCM presence.
• If supplied with a protective circuit module (PCM), the battery includes safeguards against overcharge, over-discharge, and short circuits. Verify PCM presence when ordering if protection is required.
• Always follow LiPo handling best practices: avoid puncture, do not expose to high heat, and store at partial charge for long-term storage.

Benefits for Designers and Hobbyists

• Slim profile fits into compact enclosures where cylindrical cells will not fit
• High energy density allows longer run time for small devices
• Rechargeable and reusable for prototyping and production use
• Optional PCM increases device safety and simplifies battery management integration

Ordering Information and Notes

• Available with or without PCM. Confirm required version before purchase.
• Images are for illustration purposes only. Actual product dimensions and connector options should be checked in the product specification sheet.
• For applications requiring higher cycle life or discharge rates, consider selecting a different cell chemistry or higher-capacity LiPo variant.
