I bought one, used it about a week and ordered a second one. My older B6 chargers are 60 watts, this is 80, and yes, it does charge faster on larger batteries that can take higher currents. The alligator clips for the power lead are junk, but I use an XT60 connector to replace them and make a 10 foot extension lead from a spare battery in the bed of the truck so planes can be charged on the ground. It would be nice if it included a balancing plug extension, but they are available elsewhere. Star rating function does not work. Is that because my old computer runs Windows Ultimate?

We have 7 adult and 2 rapidly growing dogs in a 3 acre lot enclosed by a 2 meter perimeter wall. There are other dogs nearby, and our dogs tend to stay near the car gate and bark, especially at night. This has been a problem for years. The box arrived about 5 days ago and I installed it on the gate about noon. There has been almost no barking at all since then! We have a large piece of land, and I might order a couple more of these to install elsewhere, but the first one DRAMATICALLY AND IMMEDIATELY reduced the problem! Amazing!

I only needed a set of balance plug sockets for my B6 chargers. For a couple bucks more, got these. Curious that it has 4 automotive type spade fuses, but they are not removable/replaceable as they appear to be soldered in. If one blows, can probably get the back off of it and replace it, but it would be more convenient if they simply pushed-in.

Not used any of these yet as they just arrived, but bought and used them in the past. They are great for small planes where 4 channels are adequate, very compact and light. I have never range tested them, as the small planes I use them on don't go out more than maybe 250 meters. I have used them with DX6, DX8, and Orange RX transmitters, all work OK.

Product looks OK, but the bag DOES NOT CONTAIN 10 PAIRS. It contains 5 pairs, i.e. 5 male and 5 female. Maybe this is primarily a translation issue.

PaulFillion Yo randomguy - A higher C battery has less internal resistance and will deliver a slightly higher max amps and MORE THRUST, not less. Higher weight will create more DRAG, but the effect is only significant at very low plane speeds, when the angle of attack of the wings is high. It should also be noted that all of the batteries I have bought from BG have high "C" rated stickers on them, but the batteries are all very low 'C" batteries in reality.

PaulFillion Voltage sag, internal resistance and "C" rating are related. Voltage sag is equal to the internal resistance times the current draw. The power dissipated in the battery as heat is equal to the voltage sag times the current, or the square of the current times the internal resistance. If the power dissipated in the battery is excessive, it swells and is ruined. That limits the maximum load, which is expressed as the 'C" rating. There is NO WAY that a battery with high voltage sag is 70 C!

A bit disappointed with these batteries. I have been using the Tattu 850mah 75c 4s batteries on my 3 inch quad and decided to buy these since they were so cheap and 70c which I thought would perform similarly to the Tattus. Unfortunately I was wrong. These batteries aren't nearly as punchy and they sag pretty much instantly and give a low voltage warning as soon as you give it some throttle. They are also a fair bit bulkier. I have a feeling these aren't true 70c batteries, most likely much lower c rating than advertised. However, considering the price they aren't too bad and I will still use them. If you're on a budget I would recommend these batteries for a 3 inch quad.

PaulFillion Wish I had read the reviews before ordering them. Haven't tried them yet, but hope to soon. However, the reviews read about the same as the "ZOP" batteries I have used, and they are absolute garbage. Customer service doesn't seem to understand that you can't fly an expensive model around if you don't know when it will suddenly lose power and fall out of the sky.

these was the worst battery I ever purchased. They are huge and have no power they sag almost immediately when flying. Don't do it!

I tested one of these on the same small plane as previously testing a 1184276 600 mah, 60C battery of the same brand, which was defective from the start. This battery seemed reasonably OK for the first 5 flights, but flight times were maximum 5:15 minutes, less than expected, and charging never required even 400 mah, so usable capacity was 30% below spec. However, on the 6th flight, the plane abruptly lost power at about 4:30, and testing showed 2 cells under 2 volts each while the third was at 3.3 volts under load. The 7th cycle was done on the ground to prevent possible damage to the plane and it maintained reasonable power for less than 4 minutes before the voltage on the same 2 cells crashed. A 70 C battery, which I suggest is a ridiculous claim, should last for a couple hundred cycles at a maximum 10 C load. Even if the battery were only 20 C, it should still last a couple of hundred cycles at a maximum 10 C load. A sudden reduction in flight time is even more dangerous to the plane than a battery that is bad right out of the box. Based on having tested 2 batteries of this brand, I believe they are absolute junk and do not recommend anybody buy them. The star function does not work for me, maybe my browser is too old, but I would give these the lowest rating possible.
