Features:
INR18650-35E Cells: Samsung’s Nickel-Manganese-Cobalt (NMC) chemistry delivers 3500mAh per cell, with two cells in parallel (2P) providing 7000mAh total.
Compact Design: Four cells in series (4S) yield 14.8V (3.7V/cell × 4), balancing voltage and capacity in a standard 18650 form factor.
Durability: Samsung’s cells typically offer 500–1000 charge cycles (80% capacity retention after 500 cycles), ensuring longevity in demanding applications.
Safety Features:Overcharge/over-discharge protection
Short circuit prevention
Thermal management (shutdown at high temperatures)
Cell Balancing: Maintains uniform charge across all cells, maximizing capacity and lifespan.
Rapid Recharge: Supports 1C–2C charging (7–14A), achieving 0–80% charge in 30–60 minutes with a compatible charger.
Charging Efficiency: High conversion rates reduce energy loss during charging.
Operating Range: -20°C to 60°C (performance may degrade in extreme cold).
Thermal Stability: NMC chemistry resists thermal runaway better than some lithium chemistries.
Power Tools: Cordless drills, saws, and impact wrenches.
Drones & RC Vehicles: High-power drones requiring sustained voltage under load.
Portable Electronics: High-drain devices like portable projectors or LED spotlights.
Robotics: Powering industrial or hobbyist robots with demanding power needs.
