Flat Power Lithium Battery Cell 803450 3.7v 1500mAh 5.55wh Rechargeable Lipo Polymer Battery Pack

Difference for Li(NiCoMn)O₂ and LiFePO4 batteries:

1. Ternary Lithium Polymer Cells: Pursuing a Balance Between Thinness and Long Battery Life

Core Advantages: High energy density; smaller size and lighter weight for the same capacity, suitable for scenarios with high requirements for device thickness and portability; excellent low-temperature performance, able to provide stable power supply even at -20℃, suitable for outdoor low-temperature use; flexible discharge rate, meeting the instantaneous high current demands of drones, power tools, etc.

Main Disadvantages: Less safe than lithium iron phosphate batteries; risk of fire under extreme conditions (high temperature, overcharge), requiring a high-quality protection board; shorter cycle life; faster capacity decay after long-term use; cost is affected by fluctuations in the prices of precious metals such as cobalt and nickel, resulting in a relatively high overall cost.

Typical Applications: Smart wearables, mobile phones, laptops, drones, high-end portable digital devices, etc.

2. Lithium Iron Phosphate Polymer Cells: Prioritizing Safety and Durability

Core Advantages: Safety is the biggest highlight; under extreme conditions (crushing, puncture, overcharging), only bulging is possible, with no risk of explosion or fire; cycle life is 2-3 times that of ternary lithium batteries, resulting in lower long-term operating costs; abundant raw material (lithium iron phosphate) reserves with stable and lower prices; lower self-discharge rate, suitable for backup power applications requiring long standby times.

Main Disadvantages: Lower energy density, resulting in larger size and weight for the same capacity, unsuitable for lightweight devices; poor low-temperature performance, significantly reduced battery life in northern winters or low-temperature outdoor environments; nominal voltage of 3.2V, requiring additional power management circuitry for compatibility with mainstream 3.7V devices.

Typical Applications: Outdoor equipment, backup power supplies, industrial instruments, smart home devices, power tools, low-speed electric vehicles, etc.

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.
