Rszfnjxry 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.

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.

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.

I followed the instructions about fully charging and low flights first. I thought the batteries were okay. After about two weeks of use one of my batteries went from 30% to 2% in an instant. Luckily I had enough altitude and I was just barely able to get it to land on the shore line. My drone nearly became a submarine because of this battery. I would recommend just going ahead and getting the official batteries. The only good thing I will say is that the charging station works as advertised.

Very good. Love the screen that shows the charging progress And charges quite fast
