Overview
What is a 11.1V Lithium Battery?
An 11.1V lithium battery connects three cells in series (3S) for a nominal voltage of 11.1V and a full-charge voltage of 12.6V. The 3S configuration is the standard platform for mid-class UAV motors and RC vehicles, providing meaningfully more power than a 2S pack while staying within the voltage range of widely available balance chargers and BMS modules. The 11.1V range also covers portable industrial equipment where a higher bus voltage allows smaller wiring cross-sections and reduced connector ratings compared to lower-voltage alternatives.
Applications
Common applications for 11.1V Lithium Battery cells
Application
Mid-Range UAV and Drones
Fixed-wing and multi-rotor UAV platforms targeting mid-class performance use 11.1V (3S) as a default configuration, balancing motor power, pack weight, and charger compatibility.
Application
RC and Hobby Vehicles
Radio-controlled cars, boats, and aerial platforms use 11.1V packs extensively, supported by a large ecosystem of compatible motors, ESCs, and balance chargers.
Application
Portable Industrial Devices
Handheld inspection equipment, field-service tools, and portable measurement instruments that require higher bus voltage specify 11.1V packs for compact, practical designs.

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.
