Extend your flight time with this 2-pack of high-capacity replacement batteries for your DJI Phantom 4 series drone. Each battery is rated at 15.2V and 5870mAh, providing up to 30 minutes of flight per charge (depending on conditions like wind, speed, and temperature). They're fully compatible with the Phantom 4, Phantom 4 Pro, Phantom 4 Pro V2.0, Phantom 4 Advanced, and work with the original charger and DJI GO 4 app. The intelligent power management system includes self-discharge protection, overcharge protection, and over-discharge protection to keep your batteries safe and extend their lifespan. Four LED indicators show the remaining charge at a glance. The sturdy copper terminals ensure a reliable connection with your drone and charger. Batteries come pre-charged to about 30%, but it's recommended to fully charge them before first use. Always use an OEM charger for best results. With two batteries in the pack, you can fly longer and capture more footage without constant recharging. A great value upgrade for any Phantom 4 pilot.
