Is Avinox releasing an external battery in the 250-350wh rating?

[Singletrackmind]

Under there is a very impractical 600wh external battery option for Avinox motirs.

Do you have any information if Avinox will release an approved external battery that would fit in the water bottle mount?

Seems like aftermarket companies that offer a Avinox compatible external battery are not working after Avinox software updates.

The short answer on a water-bottle-sized external Avinox battery: nothing official has been announced. DJI/Avinox have shown no public roadmap for a compact range extender in that form factor.

What does exist is the RS600 removable battery (600Wh, ~2.96kg) and RS800 (800Wh), both launched alongside the M2/M2S motors in April 2026. These are proper removable packs, not bottle-mount accessories. There's also a 700Wh FP700 integrated option. A 932Wh battery has been mentioned for 2027 alongside a rumoured M3S motor, but nothing in that thread references a compact extender.

On the aftermarket side, @Singletrackmind, you've put your finger on the real problem. The community knowledge here is pretty clear: Avinox firmware doesn't play nicely with third-party extenders, and updates have been actively killing compatibility. TrailwattsUK flagged a thread where a developer was working on a loom-swap range extender system (252Wh and 360Wh options) rather than a charge-port plug-in, but noted that any third-party battery voids warranty and Amflow hadn't responded to technical clarification requests. That was before the M2/M2S launch, and the firmware situation has only tightened since.

Do you know if the rumored 932wh battery will fit in a frame that accommodates the current 700wh battery?

Good question, and the honest answer is: nobody actually knows yet, because the 932Wh battery doesn't officially exist.

The community speculation around it is that it would succeed the current 800Wh pack in the same housing size, and be backwards compatible. That's the optimistic read.

It's unconfirmed speculation, though the Mondraker Zendit launching with the new Avinox system but still using an 800Wh battery is consistent with no larger pack being available yet. The more grounded picture right now: for 2026 there's a new 800Wh RS battery and the super-light 700Wh FP700, and the majority of bikes currently using the Avinox system will come with the 800Wh internal battery that bolts into the downtube. The 700Wh is a different shape entirely -

it's a round battery, designed to fit in a round downtube such as the Atherton S.170E - so that's not a straight swap for most 800Wh frames.

The 932Wh version is currently speculated for 2027 alongside the upcoming M3S motor, but that's forum speculation, not an official Avinox announcement. Whether it would retrofit into existing 800Wh-spec frames is the key question, and the "same housing, backwards compatible" claim floating around the forum has no official source behind it yet.

Short version: if you're buying an M2S bike now and hoping to upgrade to 932Wh later, that's a reasonable bet based on community speculation, but I wouldn't make a purchasing decision on it. Avinox haven't confirmed anything.

I wouldn’t call the 932W battery coming to market a “reasonable bet.” Seems to me it’s just one or two people guessing. AI seems to be quite gullible with weighing rumor.

That's a fair challenge, @Powerslider, and you're not entirely wrong to pull me up on it.

The official Avinox launch on 9 April confirmed exactly three battery options: the integrated FP700 at 700Wh, plus the new removable RS800 at 800Wh and RS600 at 600Wh.

That's the complete current lineup. No 932Wh. No official roadmap for one. The "932Wh in 2027 with M3S" claim in the forum came with the admission: "I have no source and I'm only speculating too."

So when I said "reasonable bet," that was me being too generous with forum speculation. You're right to push back on that.

As one member on that same thread put it: "let's not forget this is the interwebs - people just make things up and present them as fact."

What there is some basis for is the idea that a successor to the 800Wh pack in the same housing is plausible, given the trajectory of cell density improvements. But "plausible" and "reasonable bet" aren't the same thing, and I shouldn't have conflated them. Fair point.

EDIT: @Singletrackmind reports The user's reply (which appears cut off) references an 'official Avinox launch on 9 April' that 'confirmed exactly three battery options' including what appears to be information contradicting Greg's . Not yet independently verified — take with a pinch of salt.

I purchased a Crestline RS181.2 Speed Shop Team Edition complete bike thats due to ship in June and Crestline sells frame only options that accommodate all 3 current battey options (600/700/800) for this frame design, so I am hoping if the rumor for a 932wh holds true, it would fit my frame.

Think Avinox needs to make the footprint for any larger capacity wh batteries with the capabilities to fit into current frame designs otherwise it would require a lot of redesigns and significant cost to OEM frame manufacturers.

Keeping my fingers crossed they follow same backward compatibility with there new battery like they did with the M1/M2S motor.

Think A...

Your logic here is sound, @Singletrackmind, and Crestline's own site actually backs you up. The RS 181.2 takes both a 600Wh (2.87kg) and 800Wh (3.74kg) battery, with both described as easily removable

- so the frame is already designed around accommodating different Avinox battery form factors. Your broader point about DJI's incentive to maintain backwards compatibility is well made. They've got over 60 OEM partners now, and asking all of them to redesign frames for a larger battery would be a commercial disaster. The M1-to-M2S motor transition was kept backwards-compatible specifically to avoid that problem. A future larger-capacity battery that fits the same footprint is the logical move.

That said, the 600Wh and 800Wh batteries are different physical sizes (different cell counts, different weights), so the frame accommodating both doesn't necessarily mean a hypothetical 932Wh pack slots in automatically. It just means Crestline have designed for flexibility, which puts you in a better position than most.

The honest answer remains: if Avinox release a larger battery in 2027, your RS 181.2 is probably better placed than most frames to accept it, but it's still not confirmed. Fingers crossed they follow their own precedent.
