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.

  • Capacity: 4800mAh (Enough to outlast your attention span)
  • Voltage: 7.4V / 2S
  • Connectors: 1x XT30 (on a 15cm wire!), 1x JST-XH Balance Plug
  • Cell Type: Li-Ion (Slow drain, high endurance)
  • Discharge Rate: 1C (It's for your hands, not the sky. Do NOT put this on a quad)
  • Weight: ~158g
  • Size: 42 x 73 x 21mm (The "will it fit" challenge. Measure your bay.)

What’s in the Box*

  • 1x Auline 7.4V 2S 4800mAH Li-Ion Radio Battery (XT30/Balance Plug)

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.

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.

Super Low Quality/Unacceptable QC
Color: Black, Size: Wheel-6 Panel
I spent probably about an hour putting it together, only to take it right back apart and pack it up to return. The dimples for half the poles were on the wrong side (double and triple checked to make sure they couldn't be spun around. The threaded ends for the wheels were freely spinning on all but 2 wheels, making it impossible to actually tighten them fully. Once it was all put together, the screens could not be folded up to neatly put it aside when not in use. All in all, this was shamefully low quality for the money spent.
