Square Lipo Battery Cell 803450 3.7v 1500mAh 5.55wh Solar Rechargeable Lithium Polymer Battery

Key Features:

Slim and Lightweight with High Adaptability: Measuring only 80×34×50mm and 34mm thick, weighing approximately 60g, this thin, medium-sized battery can be easily integrated into small or flat devices.

Balanced Performance with Ternary Materials:Utilizing an NCM/NCA ternary cathode, it boasts an energy density of approximately 160-180 Wh/kg.

Longevity and Compatibility:The 1500mAh capacity supports 6-10 hours of continuous use in small devices. The 3.7V universal voltage eliminates the need for an additional power module, ensuring compatibility with the power management systems of most small electronic devices.

Safety and Durability:Equipped with standard protection boards (overcharge, over-discharge, and short-circuit protection), its thermal stability surpasses that of lithium cobalt oxide batteries. Cycle life is approximately 500-800 cycles under 0.5C charge/discharge conditions, with a monthly self-discharge rate ≤3%. Flexible installation and easy integration: The soft-pack packaging can slightly conform to irregular internal structures of devices. Some models support pre-installed circuit boards and wiring for direct soldering or plug-in connection, simplifying the assembly process.

Main Applications

Smart Wearable Devices: Small smart bracelets, slim smartwatches, fitness trackers; slim and lightweight design fits well in wearable devices; moderate battery life provides 1-2 days of use (supports heart rate, step count monitoring, etc.).

Small Digital Audio-Visual Devices: Mini Bluetooth speakers, wireless Bluetooth earphone charging cases, portable voice recorders, small MP3 players; 1500mAh capacity supports 3-8 hours of use, suitable for lightweight devices.

Portable Medical Devices: Small pulse oximeters, fingertip blood glucose meters, mini massagers; ternary materials ensure stable discharge, meeting the power supply stability requirements of medical devices.

Smart Home and IoT Terminals: Wireless door and window sensors, mini surveillance cameras, smart lock auxiliary power supplies; low self-discharge rate suitable for long standby times; slim form factor allows for internal embedding.

Outdoor small equipment: Mini headlamp, small GPS tracker, portable walkie-talkie (backup power supply), compact and easy to carry.

Mobile terminal accessories: Small mobile phone battery case, wireless charger with built-in battery, portable power bank (mini version), slim design does not increase the size of the accessories, and has strong compatibility.
