I think Levo plug doesn't have a real charging protocol neither energybus.
Plug a Logic analyzer or a voltmeter to your original charger and you'll see just 4.8v fixed to the brown cable.
I need some volonteers.
Yes, I read around to apply 41.5v to main pins and 5v to data pin. I tried but charging not start.
I suspect a water damage too, but if I recharge directly to cells, mission control says "all good!"
None is interested in battery reverse engineering here? Wrong forum?
I need a turbo levo DIY charger. I tried with standard 42v lithium charger and a LM2596 to supply 5v to brown cable inside the battery, but nothing happens.
I tried, first the 5v, then the 41 / 42v and viceversa. I tried with a lab power supply at 41v too.
Any suggestions?
