Performed better than I expected. If you need serious power, this battery is definitely worth a look.

I used Tattu r-line battery for my quad, it’s very powerful, when I flight quad to test it and found that it has lower internal resistance and lower landing temperatures, great!

I have yet to fly another battery that can even come close to the performance of this battery. If u wanna be on top of your game , with high discharge rate and little to no sag, you have to use this battery.

So much punch through out the throttle range...you can feel the power! I highly recommend it.

First, let me tell you I am no battery expert and this is not a controlled review completed in a lab. This review was done on my quad, flying it. I was flying this batteries baby brother the 1300 4S 75c and thought it was da bomb, but once I strapped this onto my little 4" quad, I was astonished by the amount of punch it had. I could punch out of just about any dive and be back up in the air in a second at tree top level. One thing that impressed me greatly, My OSD had gone out and totally lost track of time. I depleted my battery down to around 2.7 per cell (when I took it off of the quad). Figuring the battery was a throw away now, but still going to try and recover it, I plugged it into the tester and all my cells were back at 3.52 ish. So, I charged it up just to see, that was two cycles ago and it is still going strong. I am sure I lost a little life in it, but the fact it recovered was amazing.

Great lipo' minimal sag can take a beating being under an x frame quad I always balance charge them at 1.3 and for as many cycles that I have put them through they still behave as if new. I have no reason to try another company they are awesome and customer service and shipping is top notch!

It's great FPV battery for my drone, high burst. Great ! I recommend it~
