7.4V 2200mAh rechargeable battery is a compact lithium-based battery pack commonly used in small to medium electronic devices, RC models, and other portable systems.
Voltage: 7.4V
This is a 2-cell (2S) lithium-ion or LiPo battery pack.
Each lithium cell has a nominal voltage of 3.7V, so 3.7V 2 = 7.4V nominal.
Fully charged: 8.4V (4.2V 2)
Safe discharged limit: 6.0V (3.0V 2)
Capacity: 2200mAh (or 2.2Ah)
Provides 2.2 amps for 1 hour, or 1 amp for 2.2 hours, etc.
More capacity = longer runtime.
Rechargeable Type:
Could be Li-ion (e.g. made from 18650 cells) or LiPo (pouch format).
Li-ion = safer and more durable
LiPo = lighter and more powerful for high-drain use (like drones)
