YoWoo Power Graphene Battery 14.8V 5000mAh 100C 4S LiPo Battery with EC5 Connector Compatible with RC Cars RC Buggy Truggy Crawler Monster Quadcopter Airplane Car Boat Truck RC Hobby

The Yowoo Lipo battery, is absolutely a beast. I tried it already in my Armma Notorious today, and it was punching out power like crazy.Yowoo, as I found out, is the same company behind the HRB Lipos. For those of you who are into the RC scene, then you already know how good and what a great value, the HRB Lipos are. Well, this new Graphene Lipo by them, is no exception, is just as punchy and powerful, as their HRB brand Lipos.I did noticed that this Lipo pack, does seem to put out more power than my other HRB Lipos. It is rated at 100C, so that might have to do with the extra power of the cell. When testing it, I did also noticed that the cell was warm to the touch, but not hot enough to burn you. I was popping wheelies and doing standing back flips with my Notorious, like it was effortless.Overall, I must say, I am impressed with this new Yowoo Lipo. I believe is money well spent. I will try it on my other cars, such as the Arrma Talion, and Kraton. I'll see how it performs. But so far, so good.I would definitely recommend it to anyone else.

This battery provides insane power and longevity. I was able to pop wheelies with my 4s capable Arrma Vorteks while travelling 20+mph which is not possible with my 4s, 50c Hoovo lipo. I usually take a break halfway through the pack to let er cool down. Sometimes I use this 4s Lipo in my 6s cars and honestly theres not a ton of difference from when I run them on 6s. I'll post an update at the end of the season.

Can't beat it performance wise. Plenty of juice to run forever. Unfortunately, it got punctured rather easily.

Installed in a SAB raw 580. 20 seconds into flight already getting 21v battery warnings. They can’t handle 50 amps let alone their “graphene claim”. I bought two and their both going back. Both batteries have decent IR but they seriously under perform. I will stick with my Cnhl batteries . I should be receiving 21v alarms until close to the end of flight. If your putting these in a high current draw application forget it….matter a fact I doubt they would work in anything as most Rc craft a battery like this goes in pull some decent current.

These batteries are a great value. One of the advantages is size. Compared to other 4S batteries, these are tiny. They're a good match for people who don't have a lot of room under their body or who are running 8S and want to go small.Arrived with all cells charged to about 3.8V. The first charge brought them all up to 4.19-4.2 on my HTRC charger. 1C charging kept them cool to the touch.I ran it in a V4 Kraton 6S with stock electronics, 13T Tekno pinion, and 60/200/30 fluid in the diffs. With the punch set to 4, the front wheels were easy to get off the ground for parking lot wheelies. The fastest run was 37 MPH, which is pretty darn good for this setup. By the time the cells were reading 3.8V, the speed was still 35 MPH.I've uploaded a number of pictures that show its measurements, as well as a comparison with a different brand of 4S hardcase (not graphene) to show just how much smaller the Yowoo battery is. I also included pictures of the voltage reading when it was received and after a number of speed runs.The only criticism I have is for as small as it is, it's just a tiny bit wide, making for a tight fit in the Kraton battery tray. It fits, but it's snug. You could easily put it in on its side and stuff some foam next to it to keep it from moving around. All in all, I'm very impressed and would definitely look to put yowoo batteries in other vehicles.

This battery works great and is very stable. Cells are matched so it charges and discharges consistently. It never gets hot even when pushed hard. I would definitely recommend it if you need this size battery.

I bought two of these 6s battery packs to use on an Xclass racer I have set up for 12s. these packs are about 40grams heavier than my other 6s packs but those are rated for 50c, these are rated at 100c. I take care of my batteries and avoid overdischarging, so far these packs cell voltages are staying consistent and the IR levels are below 8. These Yowoo packs have a hard casing, on all 4 sides and feels strong enough to protect the cells in a crash. Shipping was fast, 2 days I think. Great batteries.

This battery is wonderfully powerful. I use it only on flat surfaces in my Typhon TLR or just practicing at the track, if I could get the handling down with this beast, anyways it runs about 70-75 easy with no pinion change. Love this battery highly recommended!
