Yowoo Graphene Battery 6S 22.2V 5000mAh 100C with Amass XT90S Anti-Spark Connector Lipo Battery for Mikado LOGO500 Align T-REX 550 600E 700E GAUI X5 Outrage 550 Hirobo SDX Multirotors EDF Jets

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.

Battery felt high quality and each cell had very low internal resistance compared to other packs which is very nice.

Graphene batteries are really cool. However upon receiving mine it didn't have the anti spark plug just a regular xt90 and every cell was under 3 volts out of the box. Overall build quality was alright but honestly sketchy quality control with this company. I'm lucky I randomly decided to check the cells voltages out of the box. Never even got to try it though.

They work great. Not sure in durabilitybyet

I've bought quite a few yowoo lipos over the past few months. I am slowly replacing all my lipos with these graphenes. This 4S is no exception, it performs much better than the other generic brands featured here on Amazon. I dont experience early LVC (low voltage cut) with these when i run my RCs hard and I get explosive torquey performance with these lipos. I will be buying more

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.

I have been happy with this battery. I will definitely buy more. I have had no issues, and they perform well.

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.
