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.

Specifications

  • Model: Auline 2S1P - A4821  (The good one) (21700 Li-Ion Cells)
  • 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.

Solar system board book:EXCELLENT, INFORMATIONAL AND FUN
Format: Board book
My niece loved this book. As did I! I always found outer space fascinating, but have forgotten many facts from my youth. When I ordered it, read it through and was very happy about all the information packed I. Such a fun book. There is even an honorary mention of Pluto. Vibrant, fun, factual, EXCELLENT! she got a astronaut costume also, so now she’s got all the tools for her imaginary space travel.

Amazon should know how to deliver books without damaging.
Format: Board book, Format: Board book
This is a fantastic book and the back has fun facts, plus a dedication the minor planet Pluto that was not included. If you are Gen-x you know that acknowledging Pluto on the back just warms yor heart. Most of the science info is on the back cover. The board book focuses on naming the planets and the artistry. I think this is great and the extra facts on the back are better for older kids who might want to pretend they are too big for baby books. This is a really beautiful book, but there was damage. The lip is all suffered up and marred (2nd picture) and where you open the book (1st picture) there is already a wear crease. I blame the defects on Amazon, but a cellophane wrap might have helped prevent the damage
