Auline 4800mAh 2S Radio 21700 Li-Ion Battery (XT30 Pigtail)

There's no worse feeling than hearing "Transmitter battery low" just as you're lining up a bando dive. Your quad failsafes, you do the walk of shame. Stop the embarrassment with the Auline 4800mAh 2S Li-Ion Radio Battery. This is the massive Li-Ion TX battery upgrade your RadioMaster or Jumper has been begging for, with enough juice to power your radio *and* your power-hungry ELRS module all day, all from one pack.

Why You Want It

We know you just spent £200 on a radio and another £70 on an external module, and now you have to buy *another* battery just to make them work cleanly. Us too. This Auline 4800mAh 2S pack is the fix. It's a dense Li-Ion brick that lives in your radio's bay, while the genius 15cm XT30 lead snakes out to power your external module. No more tiny, separate LiPo velcroed to the back of your radio like a parasitic twin. Just one battery. One charge. All day.

The Best 7.4V Radio Transmitter Battery Upgrade?

Compatibility

This is the perfect RadioMaster TX16S battery upgrade, and it fits great in many Jumper, Radiomaster, or Boxer radios that have a 2S-sized bay. The whole point is that the battery fits inside, while the 15cm XT30 wire pokes out to power your external Crossfire or ELRS TX module. You can also just power the radio itself via the XT30 if your radio supports it (looking at you, Zorro). As always, *measure your battery bay.* Don't email us complaining if you didn't.

Disclaimer

*Box contains one battery. Your radio, your skills, and your collection of crashed quads are, tragically, not included.

Still Here?

You finished the page? We're impressed. You must be *really* tired of your radio dying. Look, this is the long range FPV radio battery you want. It's 4800mAh. It has the magic XT30 pigtail. It'll last longer than your mate's terrible FPV "edit." Stop scrolling, add it to the basket, and go get some stick time.

Mostly great, except one little annoyance
Color: Black&Silver, Color: Black&Silver
Pros- lightweight, small, very accurate, easy to clean, timer included. Cons- I use this to brew espresso on my Breville Touch and to get an accurate reading, you have to place something flat (structured) under the scale. Otherwise the reading just jumps all over the place. I know lot of espresso machines have the same base, so this might be an issue for some! This is my reason for 4/5 stars. It’s an easy fix, it’s just kind of annoying. Value for the price seems to be on point. It’s easy to clean. It has a timer as well as scale (nice for espresso). Buttons work the first time you push them. That’s it that’s all

A solid upgrade!
Size: 53mm, Size: 53mm
This coffee tamper has been such a nice upgrade to my espresso routine. It has a solid, balanced weight that makes tamping feel smooth and effortless, and the textured grip gives it a really comfortable, secure feel in hand. There’s something satisfying about how neatly it presses down the coffee grounds—like it was made to fit perfectly. Since I started using it, my shots have been more consistent, with a beautiful crema and better flavor overall. If you’re looking for a tamper that’s simple, well-made, and does its job really well, this one’s definitely worth it.

It's pretty

I've never had a tamper, I don't know what I'm doing. But it seems to work just fine and I like the wood.
