HazeFlight 6S1P battery
HazeFlight 6S1P High-Rate Lithium-Ion Battery Pack
– Engineered for High-Performance FPV Drones & Long-Range Models –

Product Overview
Designed by HazeFlight, specialists in drone development and RC power systems, this 6S1P 21700 battery pack utilizes brand-new BAK 45D high-rate cells. Optimized specifically for our FPV drone and fixed-wing aircraft models, it delivers a rated capacity of 4500mAh and a continuous 20C discharge rate. It perfectly balances explosive power and extended flight time, making it the ideal energy source for long-range cruising, racing, and endurance flights.
🚀 Key Features
· Optimized for HazeFlight Aircraft
Developed and validated by the HazeFlight design and testing team to ensure perfect integration and peak performance with our drones.

· Premium Cells & Precision Matching
Features INR2170-45D power cells, each with an internal resistance of ≤3.0mΩ. Rigorous sorting and matching ensure a cell-to-cell resistance variance of <0.2mΩ, guaranteeing consistent output and extended cycle life.
· High-Conductivity Laminated Welding
Utilizes a unique welding process combining 0.10mm nickel-plated steel strips with 0.20mm T2 copper strips. This significantly reduces internal resistance and heat generation, supporting sustained high-current discharge without voltage sag.

· Aviation-Grade Safe Construction
Built with 3mm shock-absorbing foam and double-layer thickened PVC heat shrink tubing. Equipped with 12AWG high-temperature silicone wires and reliable Amass XT60 connectors for vibration resistance, heat tolerance, and secure connections.
· Quality Control from a Drone Maker's Perspective
HazeFlight understands power system demands from firsthand aircraft design experience. Every batch undergoes real-world flight testing to ensure stable, safe, and durable performance.
