⚠️ LiPo Care & Safety Guidelines
- Always use a certified LiPo balance charger set to 4S LiPo balance mode (4.20V/cell cutoff).
- Never leave charging batteries unattended, and always charge inside a fireproof LiPo safety bag.
- Do not discharge below 3.2V per cell under load to prevent permanent cell damage.
- Store batteries at 3.80V–3.85V per cell in a cool, dry place when not in use for more than 48 hours.
