Love these batteries. Own 14 now. These have been the best performing batteries I own. I also have spektrum G2 and G1, Hoovo batteries. These top them all. Not only do I get more flight time on my rc helicopters but the size is perfect also. Most of the other 5000mah packs are wider and heavier. Some won’t hardly fit on a couple of my 700 helis but these HRB’s fit perfectly with room to spare on all my helis.

I’ve used these batteries for RC helicopters and they perform well and consistently

I've been flying pretty exclusively HRB's in my 580, 600, and 700 E RC helis for a couple of years now and I really like them. The internal resistances all stay consistently low over time. I'm usually below 2 milliohms per cell fully charged, and that is right in line with the best batteries that I have long term experience with. I think these are very competitive with the quality of those batteries. You really can't beat the price. Some of the deals on Amazon are quite amazing.

I've gone through several of these. No lipo lasts forever, but these perform quite well and good power output for the weight. I've used them in warbirds and EDFs, and they are my "go-to" brand for 6s-5000s -- having them available with the EC5 plug is a big plus for me.

First off, I fly RC Helis. I have flown them for the past 10 years. If you're familiar with RC Helis, you know you need good performing lipos with a constant high discharge rate. I have lots of experience with Lipos and at this point very weary of cheaper brand of Lithium. But there has been those few occasions where I have come across that rare purchase of excellent quality and decent price.This review is only of my INITIAL impressions. I would love to write a full review, but it simply can't be done without a long term experience a set of lipos. I have literally had lipos for 4 or 5 years until they started showing serious signs of wear. A lipo can last a long time as long as you don't abuse them. You know what I mean if you have experience with Lipos: keep them stored at 3.85v/cell preferably in a cold environment or below 75 degrees F, don't over discharge them (below 3.7v/cell), don't over charge them (over 4.2v per cell), etc. Again, anyone who has experience knows how to care for Lipos. If you don't care for lipos, then it doesn't matter the quality, you will destroy them prematurely - like a car, don't change the oil, etc. regularly, doesn't matter the make, it will die prematurely.All that being said, the great news is these batteries came nicely packaged and perfectly balanced at 3.85v/cell. They come with EC5s the same connector I use with long balance leads. No dead cells, and a low ir (internal resistance). Everything you could ask for on the bench.I have so far flew these lipos twice. That's why this review is my initial impressions. I will amend it later, and perhaps next year as well. For both flights, it was on my Goblin 700, a 12S setup with a moderate headspeed of 2200rpm with 716mm blades. I fly moderate 3d, but didn't really push it too hard, as you need to break the lipos in, but good performance. Flights were 4 mins 10 secs each, and the lipo's voltage came back at 3.78/cell. Excellent. Performance was snappy and no sluggish behavior, power was there when I called on it.But as I said, the real test is the long term because even if these lipos perform great for 100 flights this season but then degradge next season, it would have been a total waste. Any good performing well known brand (Thunderpower, Pulse, Gensace) 5000mah 40c 6s Lipo would cost twice the price; however, they not just perform well, they last. So even if I pay twice the price for a set of Pulse, but get quadruple the longevity, I still lose out in the long run.These lipos appear to be relatively new to Amazon, so I still think the jury is out on them. This is why I only bought a single pair. If they turn out to appear to be good for the long term, then i have no problem buying several more.

Excellent battery and an excellent price! I own batteries from all types of vendors. These batteries are as good if not better than any of the other high-priced batteries I have purchased in the past. I have spent up to $130 for a six cell 5000 MAH battery and these batteries? They hold up just as well if not better… Very happy with my purchase. What is even better is I got the three-year coverage on these batteries so if they ever go bad I will get a replacement. It just doesn’t get any better! Thank you Amazon and thank you to the seller.
