3.7V High Density Semi-Solid State Batteries for Vertical Take-off Drone Battery

Features

1. High Energy Density: The semi-solid state design contributes to a high energy-to-weight ratio, which is critical for maximizing drone flight time .

2. Enhanced Safety Profile: The semi-solid electrolyte is less flammable than traditional liquid electrolytes, significantly improving resistance to leakage and thermal runaway .

3. High Discharge Capability: Designed to deliver the high burst currents required for vertical take-off, hovering, and aggressive maneuvering .

4. Long Cycle Life: The stable interface of semi-solid electrolytes can reduce electrode degradation, contributing to a longer service life compared to standard Li-Po batteries .

Specification

Applications

• Vertical Take-off and Landing (VTOL) Drones: Provides the high power density needed for efficient lift-off and stable hovering.

• First-Person View (FPV) Racing Drones: Offers high burst discharge for rapid acceleration and maneuvering.

• Agricultural and Industrial Inspection Drones: Suitable for long-endurance missions requiring reliable power.

Warnings & Safety Instructions

Charging

• Use a Designated Charger: Always use a balanced charger specifically for 3.7V Li-ion/Li-Po batteries. Using an incorrect or faulty charger can lead to overcharging and fire .

• Never Leave Unattended: Do not charge the battery unattended. Charge in a well-ventilated area on a non-flammable surface.

• Set Correct Parameters: Ensure the charger is set to the correct voltage (4.2V) and current. Do not exceed the battery's maximum charge rate .

Discharging & Use

• Avoid Over-Discharging: Never discharge the battery below 3.0V. Land your drone immediately when the battery alarm indicates low voltage (recommended alarm setting: ~3.5V-3.7V per cell under load) to prevent irreversible damage and potential crash .

• Monitor Temperature: Allow the battery to cool down to ambient temperature after use before recharging. Do not use a battery that is hot to the touch .

• Inspect Before Use: Before each flight, check the battery for any signs of damage, such as swelling, punctures, or leaks. Do not use a damaged battery .

Storage & Transportation

• Storage Voltage is Critical: For any storage period longer than three days, discharge/charge the battery to its storage voltage (3.8V - 3.9V). Storing a battery at full charge or a low state of charge will permanently damage it .

• Store in a Cool, Dry Place: Ideal storage temperature is between 10°C and 25°C .

• Use Safe Containers: Store and transport batteries in a fireproof container or Li-Po safety bag to prevent short circuits .
