I just had an electrician complete the installation of my bus conversion and I can't get the MP to start unless I run the bus and the dc/dc charger kicks in .
The 24v DCS lithium battery is totally flat , do I need to get it to a minimum charge before the MP will work ?
Can you see individual cell voltages in that app?
If battery voltage really is 0V, it could be damaged and no longer usable.
But maybe it's just disconnected by the BMS.
If you have a cell (or more) with 0V, that is very bad.
Might be possible to recover it, but you would need to charge that cell individually. Starting the charging with very low current.
If that battery still has warranty, better contact the seller.
i had same issue. the physical switch didn’t work anymore after several low batt warnings it shut off.
i found that in the console logging in through the cerbo gx there is a setting called “switch” it was set to off even though the physical switch was on.
i changed it in the console to on. and then turned back on with physical switch and it’s working again.
