21700 Li-ion 4800 mAh 3S 11.1 V XT60 Battery with Built-in Low Voltage System

The 21700 Li-ion 4800 mAh 3 S 11.1 V Battery is the smarter power source your FPV goggles, ground station, or field gear deserves. With genuine 21700 cells and a built-in low-voltage alarm, this pack tells you when it’s running out of juice—before your gear faceplants. Compact, durable, and rocking an XT60 output, it’s the “don’t fry your electronics” solution you didn’t know you needed.

Why You Want It

Because over-discharging Li-ions turns expensive cells into expensive paperweights. This 3 S 4800 mAh pack doesn’t just power your FPV setup—it monitors itself. The integrated low-voltage system gives you real-time alerts before damage sets in, while 21700 cells deliver the energy density and endurance we’ve all been chasing. Perfect for goggles, receivers, transmitters, or bench testing without lugging flight packs around. Plug, play, relax.
