FLOUREON 2S 7.4V Lipo Battery 450mAh 20C Lipo Batteries with JST Plug for RC Car Truck Truggy Airplane Quadcopter UAV Drone FPV (2pack)

Review for the Floureon 450mah 2s:This is a phenomenal battery for RC vehicles. I bought this battery for my 3D EPP plane due to the price, but it outperformed my expectations tremendously. The packaging is very professional, coming with a box with two smaller boxes inside for each battery. Inside each individual box, there was foam, some warning and instructions, and the battery wrapped in bubble wrap. It is 22awg silicon wire for the JST connector as well as 22awg silicon wire for the 2s balance connector. They are about 8.5 centimeters in length for the JST and 7cm for the balance connector. The packs are small and lightweight. Compared to other 2s 450mah batteries, these are not as tall but the width x length is larger. I am messuring roughly 5.5x2.75x1 centimeter (length x width x height). They mounted to the airframe well with velcro due to the larger surface area. Another thing I really liked about this battery is the cells came balanced at 3.8v each and after every use, they balanced at 4.2 perfectly after a charge. I would recommend charging them at .5a to maximize life time as much as possible. In a rush 1a should be ok. Be sure to lipo balance charge on 2s when charging these and never do a fast charge, as you risk a fire since the cells get out of balance. The discharge of the battery was great, I did not notice any sag and they stayed powerful throughout the flight. I was getting roughly 5.5 minutes of flight time with these batteries.Overall: These batteries were great and I hope they continue to perform as well as they have been. Would recommend them for any of your electronic needs that requires a battery of this size.

I use these in transmitter for an RC model. They work fine for my use case, although I don't know if that's what they were designed for. They last me all day, but I always charge them after we are done for the day. They are a little big for a 450mha battery I think, but they fit inside the battery compartment of my transmitter that could also run on 4 AA batteries. The wires seem a little thin. The connection is tight, and I feel like I am going to break the wire when I try to get one out of the transmitter to charge it I would feel better if the wires were reinforced at least at the connectors.

These batteries are fine.. But I ordered them without making good measurements of the space I was going to use them. They did not fit. THAT'S MY FAULT NOT THEIRS. I do have another use for them and I'm sure they will work good there.

It's not the most power in the world but it is very fair for the price. I've had mine for quite a long time and haven't been very nice to them. They can handle a lot of abuse and mine show no sign of slowing down

I read several reviews stating that this battery works well with the "Top Race" $99 dump truck my son has. It is the same 7.4V at 450mAH battery size as the one that come with the truck, but this one is about 50% smaller. I bought a set based on the recommendations so he would have no down time with his toy. The very first time I put this battery on charge using the USB dongle chargers that come with the truck, the battery kept charging and charging. I kept monitoring after the three hour mark just to make sure nothing was wrong. At about the five hour mark I came back and the battery was twice as fat and literally minutes from blowing up! It was super HOT, so I just unplugged it and put it out in the driveway. Be careful. Maybe I just got a bad battery but don't leave this charging unattended until your sure yours works. I am not even trying the other one. I just dumped them both and sucked the loss.

Great battery at great price. I've used these batteries as well as the 3S ones for last 4 plus years and they prooven reliable for sure.

Flying these on an Aurora 100. Getting 4 min 30 sec. No puffing or noticeable voltage sag. They might not have as much pop as the 80c that came with my Aurora, but honestly I can't tell. I do dives, flips and high speed turns. These perform just as well as my 80c eachine battery for me. Had them 2 weeks, 5-6 cycles on the charger. Time will tell, but for now I'm super happy.

Using these to power my T8SG Jumper V2 plus transmitter. Good for well over an hour maybe two at mid-range transmission power. Fit nicely into the battery compartment without modification.
