103665 3.7V 3000mAh LiPo Battery

High Capacity Power Built for the Outdoors & Professional Use.

The 103665 3.7V 3000mAh 11.1Wh Lithium Polymer Battery is engineered for demanding applications where capacity, stability, and safety matter most. Purpose-built for hand warmers, walkie-talkies, and professional wireless communication devices — this high-energy LiPo cell delivers reliable, consistent power in extreme environments where performance cannot be compromised.

✅ Key Features

🔋 3000mAh / 11.1Wh Ultra-High Capacity One of the highest-energy LiPo cells in its size class. Delivers extended, uninterrupted runtime for power-hungry applications — keeping hand warmers heating through cold winter days and walkie-talkies transmitting reliably across long field shifts, all from a single charge.

📐 Precision Slim Form Factor – 103665 (10 × 36 × 65mm) The ultra-slim 10mm profile and optimized 36×65mm footprint enable seamless integration into hand warmer housings, walkie-talkie battery compartments, and wireless communication terminal enclosures — with minimal structural modification required, reducing design complexity and accelerating time-to-market.

🛡️ Built-in PCM 4-in-1 Protection – Safe in Extreme Conditions High-performance Protection Circuit Module (PCM) delivers four-layer defense against overcharge, over-discharge, overcurrent, and short circuit. Specifically optimized for the continuous heating demands of hand warmers and the high-power transmission bursts of walkie-talkies — preventing overheating, swelling, or fire risk under all operating conditions.

❄️ Wide Temperature Range – Reliable Cold Weather Performance Advanced polymer electrolyte system maintains stable discharge output down to -20℃ — ensuring hand warmers keep generating heat and walkie-talkies keep communicating reliably even in harsh winter outdoor environments, without the capacity drop or sudden shutdowns common with inferior cells.

⚡ High-Rate Discharge – Stable Power for Walkie-Talkie Transmission Supports sustained high-rate discharge to meet the instantaneous high-current demands of walkie-talkie RF transmission bursts — delivering strong, stable signal output and preventing power interruptions or transmission failures caused by high internal resistance under load.

♻️ 500+ Cycle Life – Long-Term Reliability Rated for over 500 full charge/discharge cycles with ultra-low self-discharge rate. Retains excellent capacity after extended storage — reducing replacement frequency and delivering outstanding total value across the battery’s full operational lifespan.

🏭 Grade A Cells – Factory Direct Quality Manufactured on our own ISO-certified production line with rigorous multi-stage QC protocols.
