No. The LCE930's headtube Is designed for a traditional 1.5 tapered fork. The headset requirements for that frame are zs56 upper and lower.

Indeed you were right with 150mm. I've measured my current setup to be 630mm from crank spindle to seatpost rail + 175mm of crank arm length, this gives 805mm of leg reach, now when I subtract 410mm of new seat tube length and 165mm of new crank arm I get 230mm from seatpost clamp to saddle rails. Entering this into Dropper Post Length Calculator with 224mm of insertion length yields 150mm travel with OneUp, the same with RF Turbine R, PNW Loam and KS Integra.

Similar to the Dengfu E55.
The above link should take you to a thread which should explain furtherICR Headsets for the SZZS-specific CEF50 build
WI. Nice thing about living in midwest :)
I know that’s been discussed. And I’ve never done something like that. Is there a cookbook i could follow the build one. With the right BMS for it?
Maybe. Neeko might adapt Mike Kelly's recommended 3rd party water bottle battery extender protocol for the lesser smartness peeps (like me) with a step-by-step build video.

Oh man, now I gonna have to encourage someone else to risk it!I've given this some thought.
The issues which I fave is that more and more ebike riders are expressing concern for ebike battery fires.

Even I've had to take this onboard in terms of addressing the safety aspect. Which is why I opted to implement the entire Bafang M820 system. As apose to using the motor and a third party battery.

Then theirs the frame and how one could neatly implement a range extender without having cables protruding, without looking out of place (not looking like a DIY job).

The holes on the to side of the downtube are designed to hold the battery mount in place (as well as the attachment point for the bottle cage).View attachment 130478
So the only logical point would be to use the charge port (again, for a neat non-diy looking purpose built range extender).
Which leaves me contemplating the following:-
1. Should Bafang impliment an official range extender battery which coincides with their plug-n-play ethos (which would include a new firmware update to allow the system to recognise more than one battery being used), Shenzhen Zhaosheng would probably make a revised version of the CEF50 or possibly design a new frame to better facilitate the new range extender. Or,
2. If Bafang opts not to implement a range extender, then a third party company (by default) would need to build a range extender of a higher voltage than the main battery. However, it wouldn't work like a typical range extender. Moreso, it would work like a portable battery charger which would fuel the main battery. But the issue for designing such a range extender battery would mean that discharge rate 'could' exceed the recharge rate. Which would then lead to overheating. And then theirs,
3. Safety. Bafang have made it clear that the choice of using 2amp chargers for their batteries (36v and 43v) was intentional, in an effort to maximise battery lifespan and reduce any malfunctions throughout the charging process. Coupled with the fact that the M820 uses a xt30 connector (to reduce the amps its able to pull from the motor. Any range extender designed would need a bms to 'STRICTLY' administer current at specific times, in an effort to not put unnecessary load on either the main battery, existing wire harness and the controller for the M820 motor.
Don't get me wrong, I think about this often. Which is why I'll keep my ears to the ground and report anything and everything I learn.
But as for simply retrofitting a random bottle battery to the battery (or retrofitting a xt30 splitter to the main wire harness and running a bottle battery separately), I think we can all do better imo.

We've all come along way from diy ebikes of old, where random wires and cables would protrude from frames (looking like a bodge). Personally, I don't want to spoil the look of my CEF50 with random cables.

Unless a range extender can be implement and its a clean and safe integration, then I'm not interested in ruining the look of my own.
Sorry if that's not what you wanted to hear @TCFlowClyde
. No worries. 
Is it still the rule to never stick a metal fork into an electrical socket...I forget.
Don't sell yourself short.Oh man, now I gonna have to encourage someone else to risk it!
I might try it on my own here. Just learning to solder myself...maybe think about a soft-pack-build soon...if I prove halfway competent and don't get fried!
Just didn't want to be the first rookie builder for this thread.
So, don't touch the active soldering iron to my tongue to make sure it's ready?Don't sell yourself short.
Truth be told, I'd recommend not bothering to retrofitting a third party range extender. By the time you've put in the hard work, someone else (like Bafang) would probably release one which would simply plug into the system seamlessly.
Learning to solder is a good skill. Best recommendation is to start small.
E.g. I started by soldering connectors like xt60s to cables, in an effort to lengthen cables or make a bigger cable. Concentrate on getting a good technique, so you can solder safely
Sadly I agree. Bafang is slooowwwww on innovation... they're more copy-cat traditionally. That's why I was surprised the M820-75Nm was so nice. Guessing Forestal engineering had some massive input.
Plus, I just bought my first Amazon soldering kit two months ago...can't waste a $30 purchase after all. Maybe Bafang will save me if I procrastinate enough. 
Sounds like a build-off challenge? I risked the rear shock over-stroke... your turn?
Plus, you're likely more successful of a risk taker than me jumping those big gaps and whatnot? 
I'm not sure if you can source a empty battery case but if you can and are open to diy you could place 6ah 21700's instead of the 5ah found in it. Would get you to 864wh so right under where you want to be but still 20% more capacity. I'm not sure if you go softpack if you could fit another parallel group, if you could though that might introduce its own issues though
I’ve been thinking about it. I’ve soldered a lot of my guitar pickups and pots so I’m “ok” with soldering iron. But I’m not confident in the process but I still have to read mikes link he posted.Sounds like a build-off challenge? I risked the rear shock over-stroke... your turn?
You can do it!
Ok so I ordered the same battery, connector and ideal diode same as @mike_kelly I just need to know how I connect it all together. Any guidance would be helpful.You can do it!
Hopefully soon! Bikes are on the way.
Looks like they're ready at $15 USD plus shipping according to Linda.

Awesome! Cool to see the Big horn!
