14.8v lithium battery
What is a 14.8V Lithium Battery?
A 14.8V lithium battery is a rechargeable battery pack consisting of four 3.7V lithium-ion or lithium-polymer cells connected in series (4S configuration). This voltage platform provides a strong balance between power output and energy density, making it ideal for medium- to high-power portable devices. 14.8V lithium batteries are widely used in medical devices, professional drones, industrial tools, robotics, and mobile communication systems. For OEMs and system integrators, 14.8V lithium packs offer a reliable and scalable energy solution for demanding, mobile, or high-drain applications.
Higher Voltage for Greater Performance
Compared to 7.4V or 11.1V lithium battery configurations, 14.8V batteries deliver greater power output, enabling devices to operate with higher speed, longer runtime, and improved motor efficiency. They maintain a stable voltage curve throughout the discharge cycle and offer fast charging capability, low self-discharge, and excellent energy-to-weight ratio. With a typical cycle life of 500–1000+ cycles, 14.8V lithium battery packs ensure long-term durability and stable performance even under continuous use.

14.8V Lithium Battery – Frequently Asked Questions
How many cells are in a 14.8V lithium battery? Can the cell type be changed?
A 14.8V battery typically consists of four 3.7V cells in series. Different chemistries like LiCoO₂, NMC, or LiFePO₄ can be used depending on application needs.
Can it directly replace lead-acid or 12V lithium batteries?
Since 14.8V is higher than standard 12V, ensure your device supports this voltage range. Some systems may require adjustments.
What communication protocols are supported? Can the battery be remotely monitored?
RS485, CAN, SMBus, and other protocols are available, allowing real-time monitoring of voltage, temperature, and state-of-charge remotely.
Can the battery be customized to fit the structural requirements of my project?
Yes. We offer full customization for size, shape, casing, IP rating, and connectors to fit special enclosures or embedded devices.
