Mini 4K/Mini 2 Battery 2Pack with Charging Station, Intelligent Batteries for DJI Mini SE with Display Two-Way Charging Hub, 2400mAh 7.7V 31Mins Flight Time Rechargeable Battery

I really like the charger that comes with this kit. It's much faster than charging the battery in the drone, though it does take two USB cables to get the max charge speed. It also shows the charge level, voltage, and Amps of each battery. The batteries themselves work just as well as the one that came with the drone.

Batteries have been plugged in the charger and connected to charging adapter. No change in charge level after 4 hrs now Edit****… charged 100% using iPhone charger High quality product despite mutual hiccup

Update 10/31/25: After about 3-4 uses on each battery, they're not reliable. I take off and it says 89% charge, and get about 100 ft away and my drone lost connection and dropped out of the sky. It took me forever to recover the drone. Once I found it the battery was saying 3% on the charger. The other battery will show it's full, but after I fly for a few minutes the drone says "critically low battery, landing now" and starts landing even tho the battery is showing 90% So after losing my drone, I no longer feel safe using these batteries. I will be sure to stick with DJI batteries from now on. Charger works great. The batteries seem to work great as well. In some instances they seem to outperform the OEM battery.

Love the information given on the screen tells you in the battery is 100% full and fits three batteries much better than the OE

I have been using it for a few months and it will keep batteries topped off and ready that otherwise tend to self discharge over time. It can be hard to remove batteries from the charger making it difficult to use. The charger doesn't offer a good way to grasp the battery and off-brand batteries that are a fraction larger can get stuck.
