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.

Sturdy mount
Color: Black, Size: Fits Desk Leg: 80mm(D) x 50mm(W)
Great product, very sturdy. no doubt I trust this mount/adapter to hold my 50lb PC. Installation instructions were a little lacking in explaining what to do with the small black rubber pieces. Also, I feel it is very important to ensure the bracket is level before mounting the product - especially if you have a HDD inside your computer. Nothing to knock a star off for.

Fantastic when paired with FLEXISPOT desk!
Color: White, Size: Fits Desk Leg: 80mm(D) x 50mm(W), Color: White, Size: Fits Desk Leg: 80mm(D) x 50mm(W)
I've got this to get my gaming PC off the floor, but keep it off the desk. It delivers. It fit my FLEXISPOT EC1 Electric White Standing Desk perfectly. This PC is 39lbs and there's no sign of it slipping or sagging under the weight as the base is sturdy. The top bracket isn't perfect for this uniquely size case. It installed in <5 minutes start to finish. I used an electric hammer-drill and it cinched up the proviced T-25 screws with ease. For me there's very little that I would change except for the top support bracket arm being slightly different sized.

Great Buy
Instal was easy and it seems good so far. I need to cable manage and everything but other than that it is great. Just wish they put Rubber on more of the metal parts so it doesn’t scratch the pc case.

Great way to keep your desk organized, especially a standing desk on wheels.
Color: White, Size: Fits Desk Leg: 80mm(D) x 50mm(W)
The knob that should be able to tighten and clamp the upper part of the PC does not fit into the hole on the metal plate, so it won't hold the PC securely in place. It's useless. Updated 2/18/2026 I contacted the company about my issue and they sent me a replacement surprisingly fast. The knob on the replacement fits perfectly and my PC now sits securely on my desk leg.
