Enegitech 3S Lipo Battery 3000mAh 11.1V 30C RC Battery with Deans-T Plug for RC Car Airplane Helicopter DJI F450 Quadcopter FPV Boat Drone

I'm using this as an extra battery in my DJI Phantom 2 clone. The normal battery is a 4000 mAh 3S 35C Li-poly but I don't always need the extra run time. Instead of 18-20 minutes I get about 12-15 minutes. Weight of the battery is 211 grams vs 254 grams with the 4000 mAh battery. One minor issue is that the Deans connector is very tight, but I put some dielectric grease (silicone grease) on a toothpick and smeared some inside and it works a lot better now.It DOES get warm under operation, but not hot enough to be an issue - you can still put it in your pocket , perhaps as a hand warmer if you're flying on a cold day.

The product came very quickly. I checked the voltage and 1 of the cells in 1 battery pack and it was low.. I tried to charge and also balanced it. Still was low so I discharged it and charged it again. Still low cell. I’m going to keep an eye on it for now. Good price maybe that’s why?

So I bought 1 was kinda worried bc of price, took a little while to charge at first. Using 3A after first charge I was impressed it helped my little project piranha reach 60mph. So charged it agian and charged up very fast..... surprisingly fast checked it and wow had 12.4 volts very good battery I bought another for my stampede and slash so far so good. Will be ordering 2 more this week for these beautiful crawlers A+++

I am updating my first review with this one because I almost lost a $900 car on x2 cheap batteries. After buying 4 of these to run 6s on my RC shedder and having no problems I moved them into my Talion v4 BLX 6s only to have one catch fire. I also have some Flareon 4s x 2 in series and gens ace 6s 6000mah and neither have burst into flames. Was really hoping these would be the the last brand and style batteries I would buy. I really liked the size and was going to purchase at least 6 more to run a dual series setup but so much for that.

I bought three of these batteries for an rc Heli I hadn’t had the chance to build yet. When I first got them I saw some of the cells were very low, like 3.5v per cell (first indication of trouble). I individually charged the low cells and brought them up to the others, then I balance charged the batteries and brought them up to storage voltage (3.85v). I put them away for a few months, and after I built the model, I brought them back out and went to charge them. Well, out of three batteries, 9 cells, only 4 cells were at 3.8v. Two of the cells were 2.3v, one of them was at 1.7v and two more were at 1v ! Total garbage and a huge waste of money ! DO NOT BUY !

Great price fot a great battery and my attached picture shows it next to a 5000mah Traxxas 3s so people can get an idea of the size and in my picture you can see I am charging it on my traxxas id charger.

Great product, would recommend!Thanks for the super fast shipping!Also thanks for checking after I received the battery!

1 cell in the battery will not hold a charge as the others do .. When i recieved it cell 2 was .4 lower then the rest.. it does take a full charge but does not hold it.. when i put it back on charge cells read the followingcell1 is at 3.73 cell 2 is at 3.22 and cell 3 is at 3.73not to impressed but i have ordered another in hope it does not have this same turn out
