So with it being really chilly and with extra parts around... Took a couple of those small variable buck converters and made a multi volt input 6-60 volts
to 5 volts and 12 volts and USB ports in a box to take on my mobile repair work... This way I can test a PAS sensor, throttle or anything else.. Saves time
and makes diagnosis so much easier... pics should be good if you need hints at how to..... if need more DM me....

Nice clean project !
Q- Where do you get the input voltage from ? I hope is not from the ebike battery...

If I am in my shop I have a collection of old lead acid batteries that I use in testing ..

If I am out at customer location I have a spare 48v lithium pack ....

I get it , i thought that you would carry it on your own ebike and if needed could use it to diagnose an issue . But if powered by the ebike battery it may not be helpful if said battery goes out. That's why i was confused..

Nevertheless could still use it with an xtra pack on the ebike, it's an ingenious use of parts and very useful tool👍

What are the type of parts that you had used ?

I build distribution boxes for ebikes that people want to add 12 volt systems... the standard buck converter are large and bulky.
I found these module style variable ones. The total amp on these isn't much, so not as robust as the big ones, but for the average
person 10 amps of 12 volts is plenty... these accept 6-60 volts and can adjust the output 1.5 volt to 55 volts..
Currently I use small bike bags to make these less powerful ones...

The rest of the test box is just wires. I installed two of the modules, one for each voltage...IMG_20210123_192444602.jpgIMG_20210123_192517104_HDR.jpgIMG_20210123_192529749_HDR.jpg
