Overview
What is a 7.4V Lithium Battery?
A 7.4V lithium battery is a two-cell series (2S) pack with a nominal voltage of 7.4V and a fully charged voltage of 8.4V. The 2S configuration is the simplest multi-cell architecture, requiring only a basic BMS and delivering double the voltage of a single 3.7V cell. This makes 7.4V packs practical for devices that need more voltage than a single cell provides without the cost and complexity of a larger pack. The 7.4V standard is supported by a wide range of compatible chargers, motor controllers, and balance modules available off the shelf.
Applications
Common applications for 7.4V Lithium Battery cells
Application
Consumer Electronics and Cameras
Portable cameras, handheld video equipment, and personal care devices use 7.4V packs where a compact 2S design provides sufficient voltage and a straightforward cell balance circuit.
Application
Compact Cordless Power Tools
Lightweight cordless tools for home and light professional use specify 7.4V to balance motor performance against battery weight for intermittent-duty applications.
Application
Small UAV and RC Platforms
Entry-level drones and radio-controlled vehicles use 7.4V (2S) packs as a standard configuration, compatible with the widest range of hobby-grade chargers and motor controllers.

Key advantages
Energy
High Energy Density
Semi-solid electrolyte design enables energy densities above 300 Wh/kg — measurably higher than conventional liquid electrolyte cells of equivalent format and chemistry.
Safety
Reduced Flammability
Semi-solid cells use significantly less liquid electrolyte than conventional cells, reducing the flammable material available during a thermal event and lowering thermal runaway propagation risk.
Certifications
Export-Ready Documentation
UN38.3, IEC 62133, MSDS, and supporting export documentation available for all cells. antbattery handles the certification paperwork required for air freight and customs clearance.
OEM Support
Custom Cell and Pack Formats
Custom cell dimensions, capacity ranges, tab configurations, and pack-level BMS integration available for OEM programs. Sampling typically ships within 4 to 6 weeks of design confirmation.
