Why You

BetaFPV Aquila20 Smart 2S LiHV Battery (2PCS)

Listen, we know batteries aren't exactly the rockstars of the FPV world, but unless you've figured out how to power your drone with pure spite and UK rain, you're going to need these. Specifically designed for the Aquila20, these aren't just 'spicy pillows' in a plastic shell; they actually have more brain cells than your average YouTube commenter thanks to the integrated smart management module.

Why You Want It

Most batteries just sit there and drain themselves to death because you forgot to unplug them. The Aquila20 Exclusive Battery is actually helpful. It features a power button sequence (short press then long press) to wake it up, meaning no more accidental sparks in your bag. Plus, it has a built-in sleep mode. If you forget it's plugged in for 30 seconds after your flight, it shuts itself down. It’s basically the only thing in your kit that’s actually looking out for your wallet.

Specs

  • Capacity: 1100mAh
  • C-Rate: 15C
  • Weight: 52g
  • Connector: BT3.0
  • Battery Type: 2S LiHV
  • Dimensions: 68 x 37 x 29 mm

In the Box

  • 2x Aquila20 Exclusive Smart Batteries
  • 1x Battery Storage Box (Because keeping them loose in your pocket is a bad idea)

Compatibility

Exclusively designed for the BetaFPV Aquila20 HD FPV Kit and the standard Aquila20 FPV Kit. If you try to jam this into a toothpick build with a hammer, that's on you.

Highlights

  • LED Status Indicators: Blue means go (75%+), Red means 'land now before gravity takes over' (<20%).
  • Accident Proof: The power button prevents the drone from turning into a very expensive paperweight in your backpack.
  • Smart Sleep: Automatically powers down 30 seconds after disconnection. It's more disciplined than you are.

Notes

Shipping batteries is a nightmare for customs. If you live on a remote island or somewhere particularly spicy, check our shipping policy before hitting buy. We don't make the rules, we just follow them so we don't get arrested.

Disclaimer

Batteries are flammable. Don't poke them, don't eat them, and don't leave them charging while you go to the pub. Simple.

Still Here?

You're still reading about battery capacities? You must be a real spec-nerd or just procrastinating. Grab this 2-pack of Aquila20 LiHV batteries and get back in the air. Shipping from our UK warehouse means you won't be waiting until the next decade to fly again. Add to cart, you know you need the flight time.

Works amazingly, but only if you install it correctly.
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
If you purchasing Siless Liner 157 mil (4 mm) Sound Deadening mat, to block unwanted sounds in your car, this is what you need to buy. But wait! It's not the only thing you need to buy if you want to "actually" deaden sound. By itself, it will definitely block a noticeable amount of sound, and, most likely, that's all you realistically need. But... But... If you want the Siless Liner Sound Deadening Mat to really help you take it up a few notches, to get the best sound almost bordering on soundproofing, listen up. You will have to install traditional butyl rubber first. Doesn't have to be the Siless brand, but I'm sure they would love to sell both to you, I used both Killmat (80mil) and Noico (50mil). I have a Honda S2000. It's a two-seater convertible sports car if you don't know what this car is, and it's loud when I'm driving above 60mph. I also happen to have a sound system installed as well. Other than that, the car is stock. I first installed the butyl rubber on the car's interior sheet metal. I went all out and covered everything I could. I didn't need to but I wanted to. I was extremely impressed with the results. But I wanted to go further. Not because I needed to but because just wanted to see what it would be like. So I bought Siless Liner 157 mil (4 mm) 36sqft Sound Deadening mat to go on top of the butyl rubber mats. I put this over every area I installed the butyl rubber. I had to be careful of clearance issues since I added a significant amount of underlayment, and you should too. If you put butyl rubber sound-deadening materials in 50% of the total interior area, you'll hear a noticeable improvement. If you put butyl in about 80% of the total area, you'll be even more amazed at the improvement, compared to before. I originally did all the above myself, so that's my experience and so your mileage may vary. I then installed the Siless Liner Sound Deadening mat over every place I could even going further than I could with the butyl rubber. I used the Siles Liner in areas where butyl rubber would not have been effective, such as the roll bar hoop area and large empty cavities or holes. I covered everything I could, firewall, doors, floor pan, transmission tunnel, trunk, trunk lid, fuel tank area, rear quarter panels, and rear-wheel tunnels, in Siless Liner Sound Deadening Mat. WOW!! The Siless Liner Sound Deadening Mat was the icing on the cake! Let's not forget, this car is a convertible sports car so it will never be a quiet ride, ever. But I can now actually have a conversation with a passenger at a normal-ish volume! This also means I can now have a normal hands-free phone call without having to plug one ear to block out the noise! My sound system sounds so much better! Just by going through the install process, I looked for any vibration, rattle, squeak, and noise-prone areas to either eliminate or reduce unwanted noise production. If you forget this step, the inside and outside of your car will rattle and buzz. I skipped this step the first time around. But did it right before I installed more butyl rubber and the improvement was impressive, especially inside the car. Outside the car, I didn't notice a difference until I put the last layer of Siless Liner Sound Deadening Mat. The sound deadening mat works both ways from what I can tell. If I turned up my music, as loud as I occasionally do, parked in the attached garage to the house, with the garage door closed, I would be barely able to tell the car was playing music in the garage. It sounds like it is another car, just a little bit down the street, with a very loud base. If you stand 20 feet away outside the car, the sound system is noticeable, but not obnoxious by a long shot. Get a 3 piece wood/metal roller set as well, which makes quick work of large areas.

Better than Kilmat
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
Great adhesion, and you can immediately see the sound difference when you rap the area and compared it to another area without it. Also, very easy to cut and apply. Once on, you may not be able to peel it and reposition it, so be sure where you want it.

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.
