SCHWARZWILD Bafang M820 with LCE 930 frame

[KaroKönig]

Paint-job part 1:

First white…

then Fox-orange…

gold-green-blue effect

 

[KaroKönig]

Paint-job part 2 :

Fine-sanding of the clear coat and stick on the painting templates

Mist black-orange and then paint over the effect paint…

Finally clearcoat

 

[KaroKönig]

While the paint dries I start building a 13S2P battery with 21700 cells…

Depending on the range and weight of the bike, I might add a 13S3P battery or add a small range extender

Looks great!

Your 13s battery. Did you get a 48v version of the m820?

No , they loaded the 43 V software for me.

Smart way to do it! Did you drill a hole innthe frame?

 

[clix]

@KaroKönig , considering that this hole is meant for the brake, where are you planning to route the rear brake than?

Also, did you check, if at full compression, hole at the end of the chainstay stays big enough, so the cable doesn't get pinched between the chainstay and seatstay?
Other than that, looks neat.

 

[Mabman]

Proper!

Yes, I had to drill a 4mm hole, but the dropout is made of solid material so there shouldn't be any problems ( I hope )

Of course, the brake line also fits through and for the clearance at the dropout I had to make a 3mm edge break and reinforced the cable with shrink tubing

It's different I'll give you that, I have a spray shop and this winter I will put a new colour scheme and decals on mine

 

[KaroKönig]

I swapped out the headset that came with it for a Ritchey one.

Before I can lay the brake line, the battery has to be finished...

Enough place for 700 Wh

Nice!

 

[KaroKönig]

In order to fix the battery and attach the dual battery discharger, I made an aluminum bracket…

I attached the connections for the range extender and the charger with a rubber stopper and pull them out of the frame when necessary, I couldn't think of anything better

If you’re using axs, you can use the exit hole of the derailleur line for the range extender but it’s a bit far

[KaroKönig]

Range extender and battery module work perfectly

So your battery is 48v and your motor 43v?

 

[KaroKönig]

So your battery is 48v and your motor 43v?

That is correct. The motor only goes into overvoltage protection at 55.9 V, so I decided on a 48v battery to get a little more power

How did U charge your internal battery?

Behind the rubber stopper I have the connection for the range extender (XT 60 plug) and the charging connection for the internal battery (XT 30 plug)
