2 Packs YPG 4S 14.8V 1500mAh 70C LiPo Battery with XT60 Plug For RC Mini Racing Drone FPV Quadcopter, Perfect For 210 Quad Frame, Eachine Wizard x220, 250 Racer, AR Drone 2.0, Walkera F210, etc.

Man! I was lucky to grab the last of these while they were in stock. They were the cheapest ones on Amazon for only $37 for both. I figured why not give it a shot. My Kingkong 260 quadcopter is really finicky about 3s batteries and noticed random power lost causing the drone to drop for no reason. With 4s batteries, I did not have the sudden drop in voltage nor current. so I got these hoping they would work and for 1500mah battery, I was hoping for a descent fly time at moderate to near aggressive use. Well...I got more than what i expected. These batteries perform incredible!I got on average of 10 minutes of flight time before my voltage buzzer went off. Bottom line is that's plenty of time to fly and I got two of them dirt cheap! When these bad boys are available again. I'm jumping on them!!

Only one of the two I received actually worked for more than a couple days. I have an actual LiPo charger but one of the batteries gave up after light usage. The other one is still working though.

UPDATE 2GARTT customer service has been emailing with me back and forth. They were very inquisitive about why the batteries I received weren't functioning properly. I received a refund for my batteries. And helped answer their questions about the batteries I received so they could improve their product. Overall I'm satisfied with their customer service and will be buying more batteries soon.UPDATEOnly one battery functions like it did when I first received them. The rest have either died or barely hold a charge anymore.Bought 4 battery's total for a quadcopter I have. 3 of them still charge and work great but one won't take a charge anymore.

First off I will say that I use these batteries on a very amp hungry racing quad and I need high amp draw.These batteries are good. but not the best. They definitely allow for some good amp draw but are not as good as some other brands such as Tattu. They are deffinetly a high C rating but I'm not sure if they are actually 70c as I have no way to measure it. But I can tell compared to other batteries that the voltage tends to sag a lot more on these than with other more expensive 70c batteries.Overall these are good batteries and if you are not doing a type of flying which requires 50 plus amps at times these batteries will work great.

Both batteries died already. First one died a few weeks ago and the second one yesterday. I was checking the warranty dates to find that the return deadline was 4 days ago! I am displeased with these batteries.. one month of use and they are trash already and I cannot return them! Will not buy again

Bought 4 of them, the price is good but for some reason I'm having a terrible experience with them, not sure if it's a manufacturing issue or what but after only 4 charges I feel that the power is terrible. I need more batteries but will have to look for a different brand/model.

These are about the same size as the popular 1300 4s but offer extended flight time, I get a couple extra minutes of flight with these compared to my 1300's. They are built well and work great.

These batteries have some punch, put them on my FPV quadcopter, the thing just screams. The difference between 3s and 4s is night and day, I got about 12 minutes of flight time on a single charge, landing with 3.78v per cell remaining (light to medium flight). Your time may vary depending on your setup. Charged at 1.4amps took 54 min to full and the battery took 1520mah stated on my charger.
