I have noticed that my Cyrix-Li-Ct limits the charge of my Victron SuperPack batteries (3x200ah Victron SuperPacks) to approx 13.4v.
The Cyrix-Li-Ct terminal 87 is connected to 120Amp fuse then the vehicle's battery via a 1/0 cable to my vehicle's battery. Terminal 30 goes the batteries; terminal 85 goes to batteries pos and 86 to my negative bus bar. This was the wiring recommendation from the battery seller.
When I start the van I see the voltage around 13.40v and the amperage as a negative number and within a minute or so it jumps to a positive number (+100 amps) and the voltage increases to above 13.6v but then a couple minutes later it drops to lower positive numbers. The battery voltage rarely reaches 13.5v and current will get as low as 18 amps. 3 BMV712 screen shots attached
Do I need the Cyrix-Li with the SuperPacks? If so, do I have this correctly wired? If correct, why aren't the batteries charging to 14.2v?
