Brellavi Wireless Charger, Black

I bought this set for my Husban X4 H107C, and it works perfectly. The 500 mah batteries have extended my flight times by about a minute, with no obvious decrease in agility.As others have said, the charge ports are quite tight when trying to insert or remove the battery connectors, but there is a very easy fix. Simply separate the two halves of the charger body (they are press fit, so there is no adhesive to cut through or replace) and set the board aside. Then using a small file or some sand paper, slightly enlarge the ports. It seems that the "top" of the charge ports were the tightest.After this small adjustment, my batteries click into and out of the charger much more easily.

Nice battery set for the Hubsun H107C. Charger lights are red until the respective battery has charged. You'll need a USB "wall wart" to charge if you don't want to use your computer USB port. I've had success using an old USB charging adapter for a Motorola cell phone. Due to the nature of Lithium batteries, I'd recommend that you charge these on a surface that is not flammable and that you keep flammable materials away from them while charging. Lithium batteries can also react to water exposure so if you get one noticeably wet, go ahead and retire it.

Just received these 10 hours ago, it took 2.5 hours to charge all 6 at once, i connected the power cable to a usb 3 extension cable, so i can place these far away from my computer while charging and in hopes it would use the extra power from usb3. Next charge I'll use usb2, then a phone wall adapter and update here on charge times. I did not time the charge life, will do in the morning (almost 1am now), but i am certain it was liner than the stock 380mAh battery. I've used 4 of the batteries and had issues getting 1 to fit, it gets caught on some thing inside the fuselage, but flipping it over worked, and 1 seemed to last significantly less time than the others.These are tight in the hubsan x4 h107c, but fit good and if anything, they made it fly a bit smoother with the added weight. I noticed no difference in obtainable height or movement speed with the batteries, although if you cut the throttle mid air, it drops faster! It does take an extra 5-7% throttle for take off and hovering at eye level.

Batteries are a bit longer than the stock one that came with my Hubsan X4. However, they still fit in the drone (with a little finagling) and work just fine. The charger is great. I don't know if it prioritizes 1 battery first or charges all of them at the same time - all I know is that I plugged them all in and 30 minutes later I had 6 full powered batteries.

Even though the company says the batteries are designed to fit my Hubsan X4, they really don't fit well in the battery slot on the quadcopter. The recommendation by the Hubsan company to twist the battery cables together and slide them into the battery compartment is a poor statement when using the Keenstone batteries because there is little room for this when the battery is slid into the battery compartment. Forcing the wires in causes me to fear that I may damage the electronics in the quadcopter. The Keenstone Batteries are considerably larger than the 'original' battery that came with the quadcopter.

I'm running these on a Syma X11 and they have been working great. Easier to get in/out than the original 200mah battery since they actually stick out the back just enough to grab them and no need to pull by the wire. I originally tried to do an initial charge on all the batteries when I first received them using a standard USB charger. After the 4th was connected the charger lights started flashing. I found that I had to go to a 2a USB charger to be able to charge all 6 batteries at one time.

Really great. If you have an HS170, this is absolutely a must. My kids got HS170 quads and the batteries run out really fast. These are slightly higher capacity, but you also get 6 of them and a charger that can charge all of them. One port on mine was a little weird and loose, but it does work. The batteries do weigh a little more and it is slightly noticeable... but not a big deal IMHO.

I waited about a week for the product to be available again and the wait was worth it!Truly good quality batteries and as described by the seller, the charger is great too! The charger really do seems to have different channels for the batteries. It is not a simple "splitter". The batteries is been used in both a H107L and H107D FPV and work great, the fly time really extended. The battery IS a bit heavy for H107L, but since I fly indoors, so I don't fly it at "full" speed anyways. I also took it out for some outside flying and the battery worked great.

Batteries work great, they are a tight fit though and can require some wiggling getting in and out of the drone, should also come with a manual for the charger and have the lights numbered with the ports they go to. Am getting around 8 mins on a hubsan H107d drone which is the main reason for getting them. Shipping was fast and easy.

What a disappointment! Three of the 6 batteries are a different size and don/t actually fit into my drone. Who measures these things? Very flimsy, very plasticky and I wonder if they are even safe. Fire hazard? Beware. Charge only when you're around.

For this price the batteries alone are a great deal. Throw in a multi charger and you have a great deal. Just make sure when you plug in battery it clicks.Great product. Would buy again.

Awesome batteries. They came quick and look awesome. These will work great for my Eachine QX70.
