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.

  • Discharge Rate: 1C (It's for your hands, not the sky. Do NOT put this on a quad)

What’s in the Box*

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.

One of the best deals available!
Color: White, Size: 2 Pack
Extremely sturdy, good looking and easy to install. I have a couple of dozen feet of assorted lengths in the kitchen, bedroom, living room and foyer. Holding all sorts of antique clocks, audio equipment and cooking stuff from my flours and assorted cornmeals to cases of powdered “lemonade”.

Mounting system doesn’t align on one of three shelves.
Color: Walnut, Size: 3 Pack
Nice shelves. Install was super easy except on one of the three shelves. The main mounting shelf holes were off so the shelf will not slip onto horizontal mounting poles unless I modify the shelf. So a 20 minute job becomes a two hour job. The mounting system does appear very sturdy just not aligned.

good
Size: 23.6 Inch, Color: White
I recently added this bathroom shelf, and it’s been a great upgrade for organizing my space. It was easy to install and feels sturdy enough to hold everyday essentials like toiletries, skincare products, and small containers without any issues. The design is simple and clean, which helps it blend in nicely with the rest of the bathroom. It doesn’t take up much space but still provides enough storage to reduce clutter around the sink or shower area. One thing I appreciate is how practical it is for small bathrooms—everything is within reach, and it makes the space feel more organized overall. As long as it’s installed properly, it holds up well and stays secure. The only downside is that heavier items might not be ideal depending on the material, but for regular use, it does the job perfectly. Overall, a functional and affordable solution if you’re looking to add extra storage and keep your bathroom tidy.
