HRB 2PCS 3S Lipo Battery 11.1V 3300mAh 60C XT60 RC Lipo Battery Compatible with RC Car Truck Quadcopter Airplane Helicopter Boat

I've been using these on my E-Flite Apprentice STS and they last MUCH longer that the original Spektrum "smart" battery that came with the airplane, which by the way costs as much as twice the price of the HRB. On the Apprentice STS these are lasting over 15 minutes! The original Spektrum battery lasts 4-5 minutes if that. I will update this review once I've used these HRB batteries several more times, as I can't say anything yet about their longevity after several recharge cycles. So far I am very happy and would buy again. I am also testing the 4000mAh/6S version of these HRB batteries on an E-Flite -16 Thunderbirds and will post a review for those separately.

Always excellent quality and performance from HRB

These batteries work well for the planes. I'm using them in they last a good time.

I am using this pair in a Great Planes 300SP I have it set up with a .80 rimfire. I am pretty aggressive on the throttle and get about 4 minutes of solid flying. I am using this pair in series so it is a 6S setup. So far the performance has been good. Be advised, although this comes with two batteries at a good price, it only comes with one set of connectors so if you have to adapt from the XT-60, you will need extra adapters.

works as described

I just returned 2 different Zeee batteries because they were less than half their rated capacity when I measured them.These came out a tad over spec!They provide adapters which is another plus.The only thing is that I am not a fan of the X 60 connectors because it is very difficult to get shrink wrap to totally cover the brass under the bottom of the connector. This has nothing to do with the company. It's the nature of the connector.In fact, when I mentioned this to them they were all set to send me another one but after thinking about it, I realized it just the way these connectors are and it really would not be fair. It is easier for me to just either replace them with EC3s or use epoxy or liquid insulation.Here is a picture of what I did. I think it is the best solution. Adhesive shrink wrap!The bottom line is that these are less than half the price of Venom or other so called name brands but equally good if not better.Still can't believe how bad those Zeees were!

I purchased these for my TRX4 Sport. Easily get over an hr run time on the rocks from one of these batteries. No problems when balance charging. I highly recommend these and will definitely look at HRB for future LiPo needs

Nothing else to adds
