The OID1087187 cell uses advanced Li-Po chemistry optimized for high-rate applications. The ≤1.0mΩ internal resistance is achieved through low-impedance electrode design and high-conductivity tabs (aluminum positive, nickel-plated copper negative). At 5C continuous discharge, efficiency remains ≥90%, meaning less heat generation and more energy delivered to the motor. The high discharge platform (voltage under load) improves drone stability and responsiveness, especially during rapid throttle changes.
Intended Use: Drones, UAVs, high-drain RC models, and portable power tools requiring high current bursts.
Safety Warnings (Extract):
Storage: Keep at 0℃~35℃, ≤75% RH, with 30-60% charge state for long-term storage (3.7V~3.9V).
