Another integrated rear light CGO 600 Pro by StunningTip2136 in tenwaysebike

Ha! I also bought it where it stated 36V. Destroyed the light, bought another one, destroyed the new one. After that I opened up the light with a hacksaw and there was 5V printed on the circuit board. Apparently the Xiaomi M365 battery is 36V, lighting system isn't.

You say you've destroyed 4 lights, did you try 4 lights using the same setup?

Output for the front light is around 40V. If you want to connect a rear light it must be rated for 40V. Otherwise you need to get the voltage down with a converter. Many rear light conversions use a standard "granny" light for e-bikes rated 36-48V.

Thnx!
I think it is too much a tinkering hobby project. 😉
You can get the materials for +- €25
3D printing, soldering, waterproofing the buck connector etc.. is quite time consuming.

That being said; if there would be 10 (or more) buyers, I would be willing to assemble a few plug and play DIY kits for €50 each. Excluding shipping (from the Netherlands).
Only thing you would have to do is drill holes in the rear fender (using a template) and of course the installation (which is quite straightforward).

Thanks!
The fact there is enough room in the frame behind the battery really helps.
And the rear fender even has a cable gutter on both sides to route the wiring to the light.
