I have been sponsored by RCB for 2 years, maybe more, and have been using their batteries even before that, my first contact being Emily, and now Brennan, both awesome people. I have been using RCB in all my planes and jets previewing them on my YouTube channel https://www.youtube.com/@starsandstripesrc8475. Please subscribe. It is not because I am sponsored that I say good things about them, my reviews of my planes and flight times using their awesome packs shown on my videos tells everything in my opinion. Being in the hobby for 33 years, I have used and tested many different brands of batteries, because I was in search of packs that performed, and didn’t break the bank when it came to purchasing them. Especially 6 cell packs. This video was around 5 years ago or more https://youtu.be/BU0NfMpAD7Q?si=-BE7SjbDhdqGfLm3. This video is meant only to show some of the brands that I’ve tested a long time ago, the pricing I mention is based on around 2019, or 2020 pricing so cannot be compared today, I just wanted to show some of the brands I’ve tested in the past, and can honestly say, as they may have been decent batteries then, my long search for performing packs at a very good price ended with RCBATTERY. I fly nothing else. This is not only a preference or choice, it is also based on my experience flying them and feeling and seeing the difference in the air and on the ground. I have been very pleased with the power and performance of these packs and the awesome customer support that comes along with them. My search has ended here, and here I will stay.
