Balance chargers protect individual cells in a multi-cell pack, which is why dedicated drone chargers are usually slower than a generic USB fast charger of the same wattage.

Expect anywhere from a lunch break to a couple of hours, depending on the charger you use.

With the fastest charger listed here (Fast charger, 300W) it takes about 32 min. With the slowest (Slow charger, 50W) it takes about 3 h 12 min. Extended capacity battery for mid-range camera drones offering longer flight times for aerial photography.

Frequently asked questions

How long does it take to charge a Medium Camera Drone Battery (4S, 7,700 mAh)?
From 0% to 100% with the standard 150W charger, it takes about 1 h 4 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
Can I use a higher-wattage charger to charge it faster?
Yes, as long as the charger is compatible with the device's connector and voltage. The battery's own charge controller limits how much current it accepts, so a more powerful charger reduces time mainly in the 0-80% range; above 80% lithium-ion packs taper the charge rate for safety regardless of charger wattage.
Why does charging slow down near the end?
Lithium-ion batteries charge at full power up to about 80%, then switch to a slower "taper" phase that protects the cells from stress at high voltage. That's why the last 20% often takes nearly as long as the first 80%.
How is this charge time calculated?
We divide the energy needed (113.52 Wh times the percentage you're charging) by the charger's effective power, which is the charger's wattage times the battery chemistry's real-world charging efficiency (85% for Lithium-ion (Li-ion / Li-Po)). The same formula powers both this page and our API.
