Hmm. don’t know how to look at the code, can say that describes the result but perhaps not the process.
The UPS charger stays toggled ‘on’, but when the battery is depleted the charge goes nowhere. Not to the battery or the UPS charger. If I build up a buffer charge and manually turn on/off the UPS charger it seems to work out. So long as the battery keeps a minimal charge, power is sent to the UPS charger. Pretty sure this is not working as intended.
With a battery smaller than the full sized storage one, the micromanagement is not workable.
On the plus side, it is very much do-able to recharge bionics from the charging cable port this way. With three alternators it is fairly quick too.
