Light Carbon with Bafang M800

[hamncheez]

@KaroKönig Awesome build! I want to do the same thing as you. Can I ask you a few questions?

How do you get it to output 46.2 volts when you have 22 cells in pairs; doesn't that give you 11*3.7 = 40.7 volts? Which cells are you using, and have you weighed your battery?

Finally, have you ever ridden a Specialized Levo SL, and can you make any comparisons?

thanks

Thanks, fully charged the cells are 4.2 volts, which results in a final charge voltage of 46.2 volts. I used LG cells with 3500mAh and the weight is 1,2 Kg. Unfortunately, I haven't had the opportunity to drive a Levo SL yet.

Very beautiful bike! I like this project! Can i ask you info about adapter M500-M800?

Dear @KaroKönig I have really enjoied reading your buidt threads!?? Thanks for sharing!

Regarding weight, this frame is listed as the lightest frame at Lightcarbon.
Did you weight the bare frame, also maybe the E10 frame?
It seems a bit strange that one frame is 2800g, while a simular frame is 3600g ?

The LCES 1075 frame has weight from 3040 g ( incl. shock absorber rocker made of carbon )
and the E10 was 4150 g

Hey, this is absolutely great. Planning on using an m800 as well. Any chance you still have the measurements of width and where the mounting holes on the motor are please?

Forgot I should have quoted you probably. As from above is there any chance you still have some sort of measurements for the mounting holes please?

Thanks for making this mod as it kind of confirms that there is no vendor lock in with the M800 and Bafang F05 battery.
I was concerned that with a custom battery I wouldn't have a CANBUS to connect like official battery has and the whole thing would not work .

Just to confirm, you have the 36V M800 and you built a 11S2P battery?
I know there are 43V (the motor I have) and 48V versions of the motor as well and I wonder how they actually differ.
In the near future I'll hopefully build a 12S2P battery for extended range.
