Shenzhen Blumoti Energy Co., Ltd. is a leading Chinese manufacturer and supplier of lithium ion polymer battery 3.7v 500mah. If you are looking to source durable, bulk lithium ion polymer battery 3.7v 500mah from China, feel free to contact our factory for details. Custom orders are welcome.
Lithium-ion polymer batteries, or LiPo batteries for short, are a type of lithium battery. Lithium batteries generally fall into two categories: liquid lithium-ion batteries and lithium polymer batteries.
LiPo batteries are known for being lightweight and offering high energy density. Their nominal voltage is 3.7V, and they reach 4.2V when fully charged. For example, a 500mAh battery has a nominal energy capacity of 1.85Wh (3.7V × 0.5Ah).
A 500mAh battery is suitable for low-power consumer electronics where portability and long battery life are important. It can also be used in RC models and toys that require high power output, making it a widely used battery type across many applications.

3.7V 500mAh Lithium Ion Polymer Battery Features
- Long cycle life. As shown in the chart, after 500 charge-discharge cycles, the battery still retains over 80% of its capacity.
- Stable discharge performance. The discharge curve remains smooth without a sudden voltage drop, providing stable current output and more consistent device performance.
- Customizable high discharge rates. Batteries can be customized with different discharge rates (3C to 70C) to meet specific device requirements, making them suitable for small power tools, toys, RC models, and similar applications.
- Configurable battery packs. Two or more cells can be connected in series (2S–3S) to raise the voltage platform. With current unchanged, this increases the overall power output.
- Long-term charge retention: ≤3% per month.
Applications for 3.7V 500mAh Lithium Ion Polymer Battery
Designed for low-power discharge, typically with a 0.5C to 1C discharge rate, with an emphasis on long battery life.
- TWS earbud charging cases
- Wireless mice
- Smartwatches - battery capacity is typically 200–400mAh; capacities of 500mAh or more are more common in larger-case models or products designed for extended battery life or outdoor use
- Voice recorders / portable audio recording devices
- Reading pens / scan-to-read pens
Require 1C to 5C output, suitable for low- to mid-power applications.
- Compact facial mist sprayers / skincare mist devices
Includes micro FPV drones, indoor racing drones, RC models, and model aircraft.
These applications demand high power output and strong burst discharge performance, with common discharge rates ranging from 25C to 70C. Among them, micro FPV drones, whoops, and small indoor racing drones tend to require the higher end of that range, while RC fixed-wing aircraft, small helicopters, and mini RC cars typically fall into the mid-to-high discharge-rate range. Battery configurations are usually 1S to 3S, with capacities roughly ranging from 250mAh to 1500mAh.
Such as mini RC cars, RC boats, toy quadcopters, and other compact motorized toys. These typically require discharge rates of 5C to 20C, with 1S batteries being the most common.
