Our is on 247/365 whilst in the garage. I pop in every few days and check the battery monitor a BMV-600S and every 10/12 days run batteries off charge on a 2/5 amp draw for a day or so. To date works for me.
Could you say that in English please? I really want to know the answer to the thread question.
Both MoHo I have had the converter claims to have a battery charger but in fact its just a simple power supply unit (PSU). These enable 12V equipment to run from the mains. Since both have had a no load output of 13.7V and are connected to the leisure battery they also act as a float charger. After a day or so on EHU the battery is at 13.7V with a charge of next to nothing, the battery monitor reads 0A or 0.1A. At that current it can be left connected permanently with no damage to the battery.
I have no experience of MoHo with sophisticated multi-stage chargers, do they exit?
