I'm using these batteries in a small quadcopter, and have no issues with them. For some reason the battery indicator light flashes a little sooner than the original battery, but I think the indicator is set too high, as these batteries last far longer than the original ones (5-6 min flying at full throttle vs 3-4 mins), and having 4 batteries is such a help, allowing for much longer flight sessions. Cheap, easy, works. Would recommend.

I found my old Q2020 quad which I hadn't used in years, and I had only 2 batteries for it. These have 30 more mah, and with all 6 I will always have one charged for continuous flying if necessary. The batteries are as advertised, no problems.

These batteries are great for the money. They have a low life if you are powering a quad copter or drone, you get about 3minute flight times which is expected though. Packaging was somewhat rough, the original box the batteries and charger came in was crushed on one side but the batteries didn’t seem to have any damage, but the amazon box was in good shape.

Batteries are identical to the Hubson drone I ordered, charge quick, last the same amount of time. This charger is amazing too, makes flying better because I always have 24 minutes cumulative battery life. Only problem is that sometimes when I plug in the charger, all 4 lights come on as if they’re charging, whether or not a battery has been assigned to that slot. It makes it hard to know when batteries need to be removed, but otherwise fantastic product

Batteries fit and work fine in my protocol fx but this is a pretty small drone. About 5 inches square. All 4 batteries provide consistent fly time of 3.5 to 4.0 minutes which is much less than what the original battery did. My drone can take video but with the short run time on these batteries I dont feel I can take it outside to record and fly where I would need to, and still get it back.It will be an inside only drone with these run times.

I ordered some spare batteries for a drone I have. These fit the bill and work well. Couple of days After I received them I got an email from the seller asking if they arrived safely. Due to him having some calls about packages arriving damaged. He asked if there was anything wrong to let him know cause he would make it right. Fortunately mine arrived well and good.

Good price. The charger seems to work but the battery life is extremally short.

seems to have a slightly longer battery life than the battery my quadcopter came with (they are larger than the stock battery) i would only recommend that people look at the battery used in their respective product to make sure it doesn't cause any balance issues.
