Features:
INR18650-35E Cells: Lithium Nickel-Manganese-Cobalt Oxide (NMC) chemistry offers ~3500mAh per cell, delivering high energy density in a standard 18650 form factor (18mm × 65mm).
Lightweight: Weighs ~280–320g (depending on packaging), ideal for portable devices.
3S Configuration: Three cells in series provide 11.1V (3.7V per cell × 3), suitable for powering tools, drones, or RC vehicles requiring higher voltage.
Continuous Discharge: Supports 20–30A (depending on manufacturer), enabling high-power applications like electric tools or racing drones.
Peak Discharge: Handles short bursts of 40–50A, critical for sudden power demands (e.g., motor startups).
Durability: Typically offers 500–1000 charge cycles (80% capacity retention after 500 cycles), ensuring longevity in demanding use cases.
Efficiency: Minimizes heat generation during high-current discharges, improving performance and battery life.
Safety Features: Prevents overcharging, over-discharging, short circuits, and thermal runaway.
Balancing: Ensures uniform charging across cells in the 3S configuration.
Rapid Recharge: Supports charging currents up to 1C–2C (3.5–7A), achieving 0–80% charge in 30–60 minutes with a compatible charger.
Operating Temperatures: Functions efficiently from -20°C to 60°C (though extreme cold may reduce capacity temporarily).
Power Tools: Cordless drills, saws, or impact drivers.
RC Models: Drones, racing cars, or boats.
Portable Electronics: High-drain devices requiring 11.1V.
