My batteries go into bulk charging twice a day - (last 2 days) i have 6 Victron 220ah AGM Batteries.
They aren't in any type of load during the day so cant see why they need to restart the cycle. I checked and the rebulk setting is set to 0.40v and it says:
''Resulting Voltage at which the charge cycle will restart: 13.4v''
At that voltage the batteries are actually close to full so would it be a bad idea to drop this to restart at 12.8 to avoid over charging?
