I find the automatic sync function problematic with a system where charging can be from multiple sources (charger, solar, windmill). I also want to monitor the full cycles of discharge/charge myself. So, I want to disable it. With a 12V system I tried to put the charged voltage to 20V, the tail current to 0.5% and the charge detection time to 50 minutes. The 702 still syncs to 100% SOC after getting close to full charge and sometimes earlier.
Does somebody know how to completely disable the auto sync?
