Does anyone know in what ways Luna modified the Sur Ron to make their XX version?

Differences could be voltages, bms or discharge in the battery or controller differences.
you shunted XX controler ? or classic X controller as me but to 180A ?fechter said:The Sur-ron X controller does not have shunts. It uses hall effect current sensors. The XX mod changes the sensitivity of the current sensors, so essentially the same result as a shunt mod. This also increases the regen amount. The stock battery can't handle the increased current, so there must be some battery mod as well. On mine, I have a second battery in parallel with the stock battery to supply the extra amps.

It's a little out of date as I'm running the XX controller now. I've hammered it pretty hard and it hasn't failed yet. Mine will peak around 180A.

Seems like a creative way to move the old stock, what year is your frame?

I'm very curious what the battery mod would have been on the XX. I'm sure they didn't change the batteries but given the XX controller is too much for the stock BMS, they must have modified the BMS without bypassing it.fechter said:The Sur-ron X controller does not have shunts.
