Hello,

something weird happened with parts of a recent shipment of some "VOXL Mini 4-in-1 ESC".

The updated M0129 are suitable for 6s, as stated in the forum and docs.

I provided 6s power to one Mini-ESC from that shipment. It worked well.

I provided 6s power to another Mini-ESC from that shipment. This blew the ESC.
I was wondering but did not check further.
I tried the same with a second Mini-ESC from that shipment and it blew as well.

I checked the blown ESC-Minis, they stated "Lipo 2S-4S" at the bottom.
I check all other ESC-Minis, they also state "Lipo 2S-4S".
Weird, but to be expected (FAQ): https://docs.modalai.com/voxl-escs/faq/#q-i-have-a-m0134-6-esc-6s-version-however-the-marking-on-pcb-states-2-4s-which-specification-is-correct

From looking at the PCB I can not say, if I received (outdated) 4s-version or updated 6s-version.
Most probably I received some outdated 4S versions of the Mini-ESC? Something got mixed up?

I am confused,

• how do I know if it is 4s or 6s version (there are no stickers)
• how to get the 6s version (which I ordered)
• how to replace the destroyed components

Please advise. Thank you
