Mini 4K/Mini 2 Series Intelligent Flight Battery(2 Packs) with Two-Way Charging Hub Compatible with DJI Mini 4K/Mini 2/Mini 2 SE/Mini SE,2400mAh 31 Mins Flight Time

Batteries work without issue with my DJI Mini 4K. DJI battery fits & charges without issue. Only one battery charges at a time (even if three are installed) as the charger analyzes the batteries & starts by charging the 'fullest' one first, while the others are in 'standby'. After one battery is fully charged the charger starts charging the next fullest battery, etc., until all are fully charged. Very happy with this charger.

Terrible. Batteries only charge to about 60% (100% on the included charging station, drone registers partial battery when battery is plugged in), and on first flight with one drone crashed after 5 minutes. Waste of money

Shipped quick, works great. The batteries are quality and comparable to the name brand. Really happy with the charger. The battery charging system works AWESOME! You can actually plug 2 chargers into it for a RAPID charge, that’s the best part! Super great value for the money.

So far so good. This product works great and lasts long. Time will tell about how well it holds charges between uses.

The batteries perform well overall. Flight time is about the same as the original DJI batteries, roughly 30–31 minutes depending on conditions, and the two-way charging hub is convenient for keeping multiple batteries ready to go. My only issue is that the drone sometimes misreads the battery level, showing more charge than is actually left. It hasn’t caused any crashes yet, but it can be a little stressful if you’re counting on what the drone estimates. Still, for the price and performance, these batteries are a solid option—just be cautious and monitor the battery during flight.

The charger works great. The charging status display helps clarify the stages of charging.

The charger has been working well. The batteries, however, have been a disappointment. When they arrived we flew our drone with them no problem. Six months later it’s a different t story. While taking off, the drone lost all power and fell about 6 feet. We thought we hadn’t fully charged the battery. We confirmed the other one was fully charged. We did a slow take off and low flight and all was looking good. We started to go higher and ascend faster and the second battery died as well. The drone fell about 20-30 feet and broke several parts. Avoid avoid avoid.

So far so good. I saw a few negative reviews that mentioned the battery would die during flight, causing a crash. I flew a few times with each, and they performed as well as the original DJI battery. The charging hub works great, and even allows you to use it as a power bank (to charge the controller, for example). Definitely the best price I could find for a charging hub AND 2 batteries considering the price of just a single battery. Would highly recommend.
