Product Reviews

OK ????

After using for a couple of weeks there are still working good however, They have started to puff up. The one that came with my quadcopter still looks and works good. These still work but I worry about charging them. I fly RC Air Craft and hear a few stories at the club of battery fires. I only charge them in a safe place. If anything happens I will update this review.

LED Lights not consistent when charging & connections very loose

I think the batteries are fine but the charger has problems - the LEDs do not light consistently, so I can’t tell when and which battery is being charged. Fiddling with it helps - I think the contacts might not be lining up so I might open it up and fix that. As well - the connectors are very loose. The battery terminals slip out at the slighted bump. Should definitely fit in more firmly. I primarily purchased it for the batteries for my Syma X5SW, but I would like to have a consistent charger.

Bought these as additional batteries for my Falcon Pro drone. Work well and provide about 8 to 10 minutes of flight time. Charge quickly. Batteries do get warm when they discharge.

The duration of the batteries not as expected plus the charger is very weak to charge the batteries in a timely manner.

One at a time…

Bought these for my drone and although the batteries hold a charge, the provided charger does not work. Some ports will work intermittently, but it will never charge all the batteries at once. It would have been nice to not have to use my original charger and charge them one at a time. It takes hours to get ready for our next trip to the park

The quality on the charger is VERY poor. You have to tinker with it to get the light to come on, and presume its charging only when the light comes on. It does not have an AC to USB plug either. That is usually a staple in most households these days. The batteries work as advertised, so not a total loss as long as I can keep them charged!

Better than the rest so far.

Better than the others, but still wish they would come up with a better charger, as so far all but this one are not worth it.

More power!!!

Love having more flight time and photo/videos.Only issue I did have is with the 4-way charger unit.When some of the batteries are plugged into it, it is hard to disconnect after they are done.Also, the USB charging cable should be a little longer.Other than that, it is a wonderful tool.
