Rechargeable lithium-ion Polymer Battery 3.7V / 3.85V | Custom LiPo Battery | Blumoti
A 3.7V 180mAh rechargeable lithium polymer battery is a small LiPo battery designed for wearable devices, Bluetooth products, and compact consumer electronics.
These devices usually have limited internal space and irregular layouts, so they require ultra-thin, lightweight, and custom-shaped battery solutions. As a pouch cell battery, LiPo batteries offer flexible size and shape customization to better fit device designs and maximize internal space.
Small LiPo batteries are generally more suitable for low-power miniature devices rather than fast charging or high-rate discharge applications, such as Bluetooth earbuds, smart wearables, sensors, and other portable electronics.

3.7v 180mah lithium polymer battery Features
- Thin, lightweight, and custom-shaped design.
Ultra-thin and custom-shaped batteries can be tailored to fit irregular internal spaces, improving space utilization. Examples include elongated, curved, and U-shaped designs.
- Low self-discharge.
Low self-discharge. The monthly self-discharge rate is 3–5% at 25°C, compared with 8–10% for standard LiPo batteries.
- Ultra-long battery life.
Under low-rate discharge conditions (0.1–0.5C), the battery can achieve more than 800 cycles while retaining 80% of its capacity
Applications for 3.7v 180mah lithium polymer battery
Most small and mini LiPo batteries are designed for low-current discharge, making them ideal for compact, low-power devices that require the longest possible battery life. Common application scenarios include:
