126090 3.7V 8000mAh LiPo Battery

Maximum Capacity. Maximum Freedom. Built for the Outdoors & Beyond.

The 126090 3.7V 8000mAh 29.6Wh Lithium Polymer Battery is the ultimate high-capacity LiPo power solution for devices that demand the most. With a massive 8000mAh / 29.6Wh energy rating, built-in PCM multi-protection, and a robust 12mm thick wide-body form factor — this cell is purpose-engineered to power portable power banks, tablets, fishing lights, hand warmers, and high-drain outdoor devices through extended, demanding usage without compromise.

✅ Key Features

🔋 8000mAh / 29.6Wh Ultra-Flagship Capacity – All-Day, All-Night Power One of the highest-capacity soft-pack LiPo cells available in its class. Delivers massive, sustained runtime for the most power-hungry portable applications — keeping power banks loaded with enough energy to fully charge multiple smartphones, tablets running through marathon work and entertainment sessions, fishing lights shining through entire overnight sessions, and hand warmers heating through the coldest full-day outdoor adventures.

📐 12mm Thick Wide-Body Design – 126090 (12 × 60 × 90mm) The large-format 60×90mm soft-pack combined with 12mm thickness maximizes energy storage within the available space — delivering industry-leading capacity density for power banks, outdoor lighting equipment, and other large-format portable devices where battery compartment space allows for maximum energy optimization.

🛡️ Built-in PCM 4-in-1 Protection – Engineered for Ultra-High Capacity Safety High-performance Protection Circuit Module (PCM) specifically optimized for 8000mAh large-capacity cell operation — providing comprehensive four-layer defense against overcharge, over-discharge, overcurrent, and short circuit. Prevents overheating, swelling, and fire risk under high-power continuous charging and discharging conditions — ensuring safe, stable operation throughout the battery’s full lifecycle in all usage environments.

🌙 Fishing Light All-Night Performance – Never Miss a Bite The 8000mAh capacity combined with a stable discharge platform ensures outdoor fishing lights maintain consistent, bright illumination through entire overnight fishing sessions — even in cold outdoor temperatures where inferior cells suffer significant capacity loss. Say goodbye to dimming lights and interrupted sessions. One charge. All night. Every time.

🔥 Hand Warmer All-Day Heating – Warmth That Lasts Massive 8000mAh capacity supports hand warmers running on maximum heat settings for extended continuous periods — delivering true all-day warmth through the coldest winter days without the constant recharging interruptions that plague lower-capacity alternatives. The ultimate power solution for cold-weather outdoor enthusiasts.

⚡ Stable High-Current Discharge – Full Power From Start to Finish Advanced polymer electrolyte system maintains a flat, stable discharge curve even under sustained high-current draw — ensuring power banks, tablets, and outdoor lighting devices maintain consistent output power throughout the entire discharge cycle, with no performance degradation or unexpected shutdowns as capacity depletes.

♻️ 800+ Long Cycle Life – Industry-Leading Longevity Rated for over 800 full charge/discharge cycles — 60% beyond 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 — especially important for high-capacity cells where replacement cost is higher.

🏆 Grade A Cells – Premium Consistency at Ultra-High Capacity Every cell undergoes rigorous multi-stage electrochemical performance testing with capacity variance tightly controlled within ±30mAh and uniform internal resistance maintained across all batches — guaranteeing consistent premium quality whether you order 10 samples or 10,000 units.
