Extender battery?

They told me at sea otter that the 600Wh would be available soon, and a 480Wh after. I was asking about the PX mounting and they showed me roughly how that would mount (which the photos out there show) on the bike. I'm planning to pick up a PX and grab the 480Wh once it's out. I'm trusting that it'll come, just wish it would fit the PL too :/

The PR would be perfect if it was a bit lighter / higher spec IMO. But the look of the PX sold me

When I talked to Amflow, they said they dont know when it will be out.
 
I'll have to see how I get on with just the internal 700. I might just wait for whatever they come up with that's smaller than 600, and baby the battery a bit on my longest rides in the mean time. Alternately I guess I have a 1300wh bike and can do huge days at full power.
 
I also find it a bit odd that there’s such strange marketing surrounding the Extender battery. :mad:The thing performs well, yet it only has a 700-watt-hour battery. It would be like if my 8-cylinder car only had a 30-liter fuel tank.

I wouldn't call 700 "only". It's enough to do almost all my regular rides in high assist modes (not full 1500 obviously, but I don't need that). I think 700 is a good number to accomodate most rides, and the extender is for those big days. I think it's the optimal e-bike model so you're not carrying around mandatory extra weight for all rides.

I was hoping to buy an Amflow or two for me and the wife, but no extender, no buy.

When the extender is available, maybe I'll buy a couple PRs if I haven't already bought a new Bosch bike with an extender.

I would buy the PRs. Charging time is fast if you need to charge on go. I have cycle group/ 3 guys on amflow/ one on uno mith/ one on Bosch gen 5 with extender batttery. One thing you can’t do on Bosch is change VPN to rid at higher speed so in uk the Bosch motor is limited to the 16.5 miles per hr.

No place to charge where I go.

I'm realizing other people are riding very differently than me. I've never been anywhere where charging partway through is remotely an option. If I'm gonna ride 30 miles, it's out and back in the wilderness, not laps at a bike park.

Same here, most of my rides are where there is zero chance to recharge, no houses no roads only alpine single trails and I never do multiple laps/parks. My tour length is in general limited by my battery.

Now before the usuals will say: simply lower the support and pedal more, on the tech and very steep trials that I do is just impossible to do without a big help from the motor or with a muscular one (other than pushing 70% of the time) .

The beauty of EMTB is that you can go and explore places where before it would have require you to push or carry the bike for most of the time.

It’s real just search amflow extender there is a French made one looks 👌

If you are referring to volabike it is not French but is a Spanish company and yet no single user review, no single user experience in any forum, not even their own video that shows it works with Avinox as It probably don't even work with the latest firmware. The company is not responding to any inquiry neither.

As the elusive official RS600 one is adopting a switching approach basically letting you decide which battery to use the volabike is designed to run on parallel with the main battery that is not the best idea.

The only real thing is their website :ROFLMAO:

In Spain, these guys style of not responding is well known.
Stay away

Technically, they announced a risky extender "plug and pray ;)" connected to the charging port without any reverse current protection for the original battery. Very commercial, very risky. Lots of complains have been posted after last firmware update rendering those expensive extenders useless

Trailwatts I believe, is working on a proper solution using conventional diodes to prevent reverse current, but it's not easy with the high current demands of the M1 and, especially, the M2S, also it requires modification of the wire harness

Na i think they are legit. Had a WhatsApp talk with them about the issue with the current firmware and they replied:

Good morning

Sorry for the delay of the reply

So we are not selling now the extender

Is still working , but it gives the message in the middle of the ride and you have to disconnect it to continue
We are working to solve it now

We can let you know once is ready to sell and you still need it

Thank you

They never answered my whatsup inquiries maybe I asked too many detailed question that they don't want to answer or they cannot provide 😉: like a video showing that it works on a M2s and that does not affect the power, but it does increase the range. Or how do they avoid the issue of running different lipo cells in parallel, this is why DJI and other manufacturers switch between RX and Main battery and do not run them in parallel. My Giant one once the main battery is low it switches to the RX, with DJI you can chose which one to run first that is even better.
DJI solution is indeed compatible with all their batteries because of the switching, running a RS600 in parallel with a FP700 is just asking for trouble with such different cells.
You can search on the hazard of running difference lipo cells in parallel.

They are even reseller of the Velduro that is one of the bikes that I currently own and when asked about test with this specific bike no answer.

The one from them for the M1 was out since a while, almost no user experience, some never got it and had to use paypal refund. Just search this site.

I’m the first to whish that it was a viable and safe option, but it does not seem so. The risk to damage your motor/battery and the risk that any firmware changes will make it useless (like now) is high. Would be tons of video and reports that works is a different story but the fact that they cannot deliver the new version because it does not work correctly is a red flag.

I really hope DJI will release a smaller one 300/400wh that hopefully would fit my bike, a 480wh would probably be too big.
Maybe somebody will reverse engineer the DJI RS600 and build a compatible one that behave the same, this one is not the case.
 
Just the other day, I ran into a well-known YouTube influencer in our mountains who had showcased the new models a while back. He told me in confidence that the RS600 in his video was just for show—the battery didn’t actually work. ;)
So it was purely a demo unit to reassure the audience…nothing more, nothing less.
He also mentioned that Amflow had been planning an extender battery for quite some time, but that the project had stalled due to the different types of cells used in the batteries. As for the design, it should at least eventually fit into frames from other manufacturers as well. I seriously doubt that will happen this year, so for longer tours, we’ll have to keep running the 8-cylinder in 4-cylinder mode. :cool:

I fully believe you that it was not working. The story about different cells is exactly the challenge if you run in parallel as those non official ones.

The RS600 approach seems to be a "simple" switch between two batteries, basically like unplugging and plugging another one, of course doing it hot is more complicated.
I think they are producing the ugly mount, cable and hopefully a compatible cable for charging with the round charger, some firmware testing and it will be available in a few months. Battery is already certified etc.
In the screen you can already see main battery, secondary battery % and temp

For a smaller one I'm not sure we will see one anytime soon, unfortunately.
 
Im starting to wonder if we will ever see an extender. It was all a farce to get people to buy their bikes.
 
Well? Anyone hear anything about an extender yet?
