5pcs 3.7v 800mAh Lithium Battery with 5-in-1 Charger for Syma X5C X5C-1 X5 X5SC X5SW H5C V931 S5C S5W SS40 FQ36 T32 T5W H42 CW4 UAV 2.4G RC Quadcopter Spare Battery

I use these in my Syma X5 drone. They were a pleasant surprise. I found that they gave me more flight time over my previous batteries (around 7-9 min). Build quality seems good. Batteries have been consistent across the board with no bad ones in the set. Included charger which works well. Batteries do not get too hot when flying or charging. They fit in the battery bay of the drone perfectly. It is my opinion that these batteries are an excellent value for the money.

good price and fast shipping

I like the batteries and charger because they do work. The female receptacle's in the charger are a little tight and at first a little difficult to fit the plugs into from the batteries. But a little patience and careful manipulating and they work fine.The only issue that I have is the advertised 800mah capacity of the batteries. It was obvious that the batteries were thinner than they other 800mah batteries that I have but I was not too concerned because sometimes higher quality cells can be smaller and still produce the advertised capacity. It also can take a couple charge/dischaege cycles before LiPo batteries start producing their advertised capacity. But these are not getting there.In my Uranhub 2k drone which is essentially a slightly upgraded and rebranded Snaptain S5C... The OEM 1000mah batteries that came with it last around 10 minutes; 800mah Uranhub replacement batteries last around 8 minutes; and 600mah batteries last around 6 minutes. After a few charge discharge cycles these batteries are lasting around 6 minutes. So I conclude that these batteries are most likely 600mah batteries.Why am I not unhappy about this? For my purposes 6 minutes is long enough and the batteries were reasonably priced. You would not believe the trouble I had finding a replacement laptop battery that actually worked right. It took 3 returns before I received a decent battery and it has 25% less capacity than advertised. Why should these little drone batteries be any different.? Chinese batteries that work exactly as advertised can be difficult to find. It is just the way it is. I am sure that the seller is just repeating what their supplier is advertising to them. Next time I will probably purchase the OEM replacements, but they cost more.

fitted directly and functioned well. Only problem being the wind got the drone….. (I wasn’t running it) and haven’t seen it since.

After looking at images and descriptions of batteries to find a replacement for my protox fpv micro quadcopter, I found it on the first try!! I knew this battery was thicker than the original but knew if I could get it past the retaining clip it would fit and I was right. This fits snuggly in the quadcopter and the connectors match. The original battery was 650 mah and this one is 800 mah. So even if it does not perform at the 800 mah like another reviewer said, I still get the same performance I was used to with the 650! I just got it today so have yet to see how long the batteries last. Pictures of the 650 and 800 in size comparisons are attached to this review as well as pictures of the copter with the battery installed.

I teach a drones class, so I purchase a lot of this type of battery. I've started marking my purchase date on my batteries. I have several batteries purchased before this set that I am still using. However, most of the batteries from this set were puffy in less than a year.

Works just fine

At full charge I can use all 5 batteries and that flight time doesn't equal to what one of the original batteries. Less than 1 minute after take off I will get the low battery flashing light on drone. I expected more flight time since the mah is higher than the original batteries
