Got in two Seplos Mason 280 kits couple weeks ago. Got the first kit assembled and hit the reset button and waited for magic to happen. LCD screen came on and there was no Voltage or SOC displayed, no individual battery voltages.

DC voltage at cable outputs is 53.7 Volt
Checking cable connections all voltages present to BMS in multiples of 3 volts.
Dip switches correct positions.

Why no magic Seplos fairy dust?

As a last resort I can take the other kit and substitute the other BMS in...

And a gripe aimed at Seplos - why are their manuals hidden behind a registration wall? Not a big deal if their registration process works but it seems to be about as reliable as my current BMS...

Did you try and hook up a small charging voltage to wake up the bms?
