Packs with higher voltages
If you have a battery pack where the maximum voltage can be higher than 70V, it is still possible to use
the 123 SmartRelay, but keep in mind that you can only switch AC voltages like the AC side of a charger.
The SmartRelay will be powered from the last four or eight cells to get a working voltage of 12V or 24V.
This will not create a disbalance because the SmartRelay power consumption is negligible and lower than
the self discharge of the batteries.
Connect the “power supply –
“ to the minus pole of the 4th last cell and the “power ” to the last
cell +.
