“2S” in a 7.4V 2S LiPo battery stands for two lithium polymer (LiPo) cells connected in series. Each piece has a nominal voltage of 3.7 volts, so the total is 7.4 volts. This arrangement in series can raise the voltage without losing capacity.
A standard 2S LiPo battery is fully charged at 8.4V (4.2V per cell). High-voltage LiPo (LiHV) variants can reach up to 8.7V (4.35V per cell).
We offer 2S LiPo battery capacities ranging from 450mAh to 7200mAh.
- 450 to 1300mAh capacities suit small remote control models and wearable devices.
- 1500 to 2200mAh capacities fit drones, RC cars, and general consumer electronics.
- Capacities above 3000mAh are designed for high-power or long-runtime applications such as airsoft guns and larger drones.
The C-rating indicates how quickly a battery can discharge its stored energy. For example, a 1000mAh battery with a 20C rating can safely deliver 20A of continuous current (1Ah × 20C = 20A).
In high-demand systems like FPV drones or RC cars, a low C-rated battery may cause voltage drops, overheating, or even shutdown. Selecting the proper C-rating ensures stable power output and extends battery life under load.

A 2S LiPo battery provides a nominal voltage of 7.4 volts. A 3S LiPo battery provides a nominal voltage of 11.1 volts. You should choose a battery based on your device’s voltage requirements and performance needs. The 2S battery suits devices that need lower voltage and lighter weight. The 3S battery delivers higher power and is better for more demanding systems.
You must perform balanced charging for 2S LiPo batteries to keep each cell’s voltage equal. Balance charging helps prevent battery damage and safety risks. Use the battery’s balance connector with a compatible charger. This practice maintains battery health and extends its service life.
The 80% rule means you should not discharge the battery beyond 80% of its rated capacity. Keeping the discharge within this limit reduces the chance of deep discharge damage. Following this rule helps maintain the battery’s cycle life and ensures stable performance in industrial or commercial use.
To ensure safe use of LiPo batteries, please adhere to the following:
- Use only chargers specifically designed for LiPo batteries; avoid NiMH or lead-acid chargers
- Never short-circuit, puncture, or overcharge the battery
- Do not leave batteries unattended while charging
- Regularly inspect batteries for any damage or swelling before use
- Store and operate batteries in safe environments away from flammable materials
