⚠️ Thermal Advisory – High Current Use
This pack is built with high-discharge Molicel 35A cells rated up to 35A continuous, but this is a heat-limited specification. For safety and performance:
- Do not attempt 35A discharge without temperature monitoring
- Keep battery well-ventilated during high amp loads
- For most UAV/FPV applications, 10-20A continuous is recommended
- Excessive heat reduces cycle life and may damage the pack
Built for UAV & FPV — Versatile for All Builds
- High Energy Density: Only 200g — perfect for endurance drones and long-range builds
- Tabless Architecture: Minimizes voltage sag and resistance
- Shock Protection: Foam padding on both ends guards against impact
- Reliable Power Delivery: Consistent output across the voltage range
Ideal Applications
- Ultralight FPV long-range endurance flights for both fixed wing and multirotor
- Cinewhoops or aerial cinematography rigs
- Robotics, RC vehicles, or compact power systems
- Portable field chargers, DIY battery boxes
Safety & Handling Guidelines
- Use a 4S-compatible Li-ion charger
- Monitor voltage and temperature during use
- Store between 3.4–3.6 V/cell in a cool, dry place
- Never short, puncture, crush, or incinerate
- Always charge on a non-flammable surface under supervision
- Never use or store a battery that shows physical damage, bloating, corrosion, fluid leakage, damaged wires or irregular voltage readings
- If a battery appears damaged or one or more cells show significant voltage deviation, quarantine the pack and dispose of it properly through a certified recycling center
- Never attempt to repair or open a damaged battery pack
