Auline 21700 S70 4500 mAh 14.8 V 4 S Li-ion Battery (XT60)

The Auline 21700 S70 4 S 4500 mAh Li-ion Battery is what happens when endurance meets engineering. Built from premium 21700 cells and rated for a solid 70 A discharge, this pack delivers consistent 14.8 V output with Li-ion efficiency. It’s made for FPV pilots, long-range explorers, and anyone who wants runtime that lasts longer than their nerves. Reliable, compact, and wired with an XT60 connector—because you’re here to fly, not babysitUnmanned Tech voltage alarms.

Why You Want It

Because flying long-range on a puffed LiPo is a bad idea (ask us how we know). The Auline S70 offers Li-ion energy density with real 70 A capability, giving you longer flight times without the sag that kills joy mid-mission. Ideal for 4-inch to 7-inch quads, fixed-wings, or ground gear that drinks amps, it keeps your rig in the air—and you out of the parts bin. In short: fewer packs, more flight, less stress.
