How to Use

1. Confirm your device’s required voltage and battery compartment dimensions before selecting a variant. Refer to the tables above.
2. Power off your device before connecting the battery.
3. Connect the battery to your device’s power input, observing correct polarity.
4. Power on the device and verify normal operation.
5. Charge using a Li-ion charger rated for the selected voltage (e.g., 42V max for 10S / 36V pack). Always use a charger with the correct voltage setting.
6. For long-term storage, charge to ~50% and store in a cool, dry place (15–25°C).

Important Cautions

• ⚠️ Always verify your device’s voltage requirement and compartment dimensions before ordering. Each variant has different physical dimensions.
• ⚠️ Use only a Li-ion charger rated for the correct voltage (4.2V per cell max). Never use Ni-MH, Ni-Cd, or unregulated chargers.
• ⚠️ Do not short-circuit, puncture, crush, or disassemble the battery pack.
• ⚠️ Do not charge a damaged or swollen battery. Discontinue use immediately if abnormalities are detected.
• ⚠️ Do not expose to water, moisture, or extreme temperatures during use or storage.
• ⚠️ Keep out of reach of children.

Safety Information

• Charging: Use a Li-ion charger set to the correct voltage (4.2V × number of cells). Do not overcharge. Charge in a well-ventilated area.
• Storage: Store at ~50% charge in a cool, dry place (15–25°C). Check and top up every 3–6 months if stored long-term.
• Operation: Do not short-circuit, puncture, crush, or disassemble. Avoid exposure to water or moisture.
• Temperature: Charge and discharge within 0°C–45°C. Do not charge below 0°C.
• Disposal: Discharge to safe voltage, then dispose of according to local lithium battery regulations. Do not incinerate.
• Inspection: Inspect before each use. Do not use if swollen, damaged, or leaking.
