Been a while since I had time to invest in scooters, but recently came upon a unit which happened to be inside the trunk of an vehicle I purchased recently.
From what I've dug up, these units are probably beyond the scope of a majority of peoples skillsets to convert with the stock hardware. Even the bottom battery compartment is milled as one piece with the hollow for the battery pack and BMS/controller which appears to specifically need communication with the IOT brain unit(manufactured by mobilogix). Throttle, brake, lights all wire through the IOT down to the BMS/Controller which wires to the motor and brake lights. Its fascinating to see the complex design, and just at first glance looks expensive and tightly safeguarded from simple hacking methods. Would be a shame if the components really cant be "unlocked" or at very least repurposed. Here's some pics of the battery pack and what I believe is the BMS/controller unit.

Is there a charging protection with some sort of anti pirate protection? Got battery off the scooter and all electrical system. I tried to charge battery pack with a 42v2a charger throught the xt30 connector but i had problems because all battery measured 12 volt and it did not start. Charged singularly and board turned solid green and display turned on with lock symbol. Plugged then charger ( brand new, steady 42v) but battery pack still doesn’t seem to absorbe amperes ... any hint?

As people mentioned here, the bms output is locked, but bms bypass is easy and charger actually charges batt. Overall hard to get out of shell, but good batt, 10s6p mj1. Have fun, be safe

@Jesus Hello sir !

I'm interested on how you bypass the bms to charge it again ! Because, the only way for me is to put another bms ( This is what i've done already on my battery ). Anyway, share it to others ! Would be nice to know ! To view images REGISTER or LOGIN for full access.

I would like to recycle this controller. But don't know what are thoses pins......

And for the battery, I decided to disassemble it. I took of the BMS and re-use 18650 elements. I add a simple 10S BMS.

I need to know the motor caracteristic too

This is the 18650 element. It's LG 3500mAh 3.6V Li-ion. Like those:

It's a brushless with hall effect sensors and certainly a temperature probe. Maybe 36-42V. D'ont know nominal power.
