Yeah this is what I do with my mk1 ZSEV. I don’t do much in terms of mileage and don’t leaver her charged to 100% unless I’m going on a drive. Can’t rely on the Zappi 2 to charge the 12v so use a maintenance charger (NOCO) to keep the 12v up to standard. I know some of the MK1s had problems with the original 12v SAICO battery but I’ve only had the odd screen warning that the 12v was low. The NOCO can be left on all the time as it maintains charge, so if there’s any drain, it’ll top it up.Mine had an odd 12v battery issue a few weeks ago. I trickle charged the 12v battery for 4 hours and there have been no issues since.
The only thing that worries me is the HV battery growing crystals inside the cells and shorting out but need to do more research on this, as I don’t really understand the risks…
