124050 3.7V 3000mAh LiPo Battery

The Market’s Favorite. Now Available Direct from Factory.

The 124050 3.7V 3000mAh Lithium Polymer Battery is one of the most in-demand LiPo cells on the market — and for good reason. Its thicker 12mm profile unlocks 3000mAh / 11.1Wh of high-density energy in a compact 40×50mm footprint, delivering the extended runtime, stable output, and built-in PCM safety that today’s tablets, Bluetooth speakers, power banks, and smart devices demand. Trusted by brands worldwide. Available factory direct.

✅ Key Features

🔋 3000mAh / 11.1Wh Ultra-High Capacity Delivers outstanding, long-lasting runtime for power-hungry portable devices. Keeps tablets running through full workdays, Bluetooth speakers playing through extended listening sessions, and power banks loaded with enough energy to charge multiple devices — all from a single, reliable cell.

📐 12mm Thick Profile – More Capacity, Same Footprint The 124050’s 12mm thickness gives it a decisive energy density advantage over standard 10mm cells of the same length and width. Same compact 40×50mm footprint — more capacity packed in. Ideal for devices with slightly deeper battery compartments where maximum energy storage is the priority.

🛡️ Built-in PCM 4-in-1 Protection – Safe & Stable High-performance Protection Circuit Module (PCM) delivers comprehensive four-layer defense against overcharge, over-discharge, overcurrent, and short circuit — ensuring safe, stable operation under all conditions and protecting both devices and end users throughout the battery’s full lifecycle.

⚡ Stable Discharge Platform – Clean, Consistent Power Advanced polymer electrolyte system produces a flat, stable discharge curve with minimal voltage fluctuation — ensuring smooth, uninterrupted performance for tablets, audio devices, and other voltage-sensitive applications, preventing performance drops, audio distortion, or unexpected shutdowns from start to finish.

♻️ 800+ Long Cycle Life – Industry-Leading Longevity Rated for over 800 full charge/discharge cycles — significantly exceeding the industry-standard 500-cycle benchmark. Combined with ultra-low self-discharge rate and excellent long-term capacity retention, this battery delivers outstanding total value and dramatically reduces replacement frequency across its full operational lifespan.

🏆 Grade A Cells – Premium Consistency Guaranteed Every cell undergoes rigorous multi-stage electrochemical performance testing with capacity variance tightly controlled within ±20mAh and uniform internal resistance across batches — ensuring every unit in every order meets the same exacting quality standard.
