5200mAh 3.7V 1S2P Flat 18650 Li-Ion Battery with PCB Protection

Product Description

The 5200mAh 3.7V 1S2P Flat 18650 Li-Ion Battery with PCB Protection delivers high-capacity, reliable power for a variety of RC applications. Built using two 2600mAh 18650 cells in parallel (2P), this flat configuration pack doubles capacity while maintaining a stable 3.7V output. It is ideal for transmitter packs, FPV goggles, handheld controllers and compact robotics, offering extended runtimes without adding excessive bulk. The built-in PCB protection prevents overcharging, over-discharging and short circuits, ensuring safe and consistent operation. Since the PCB regulates voltage, no additional balance lead is required, simplifying use and maintenance.

This battery is supplied with an XT60 connector, making it easy to integrate with RC applications such as FPV systems, small drones and ground-based robotics. The barrel plug allows for effortless charging with compatible Li-Ion chargers. Designed for performance, safety and convenience, this battery is an excellent choice for those needing longer-lasting power in a compact, flat configuration.
