Rich, are you sure about the Tail Current? I had mine at 1%. Other than that, my settings are the same on all my Victron devices:
100/30 MPPT, Orion 12/30 Dc-DC and Ac to DC 25a charger.
Absorb - 14.2
Float - 13.2

Vic, I'm quite sure. I've been through this with Battle Born in the past and they recommend a tail current of 2% to 4%. AM Solar recommends a tail current of 2%. Victron suggests 4%. There is a Victron BMV-700 series instructional video that goes over a few of these points. I'm including part of a video text transcript below regarding tail current for applications with fluctuating charge currents (i.e., solar charging).

...In solar systems or other applications with fluctuating charge currents, the ‘charged’ voltage should be set only slightly below the absorption charge voltage (for example: 14.1V in case of 14.4V absorption voltage). This will prevent the BMV from switching prematurely to 100% state of charge. The Tail current is expressed as a percentage of the battery capacity. When the charge current has dropped below this setting, the battery is considered as fully charged. The default setting is 4%, which is fine for most systems...
I've been using the settings that I mentioned previously for some time now, and to date, have had positive results. I happen to be charging primarily, that is, close to 100%, by solar, and as such have a fluctuating current, with the rare exception of regulated, dc to dc charging as required. I'm thinking that the tail current range of 2%-4% is based, in part, on whether you are charging off shore power (~2%) or fluctuating solar (~4%) - just a guess on my part - and also the state of health of a battery over time (new battery vs older battery with sulfation degradation). You are probably okay with your 1% tail current on a relatively new battery (couple years old), but at 1% it may be on the narrow end of the acceptable spectrum and may take longer for the BWV to recognize a full charge - again, just my guess. I'm no battery chemistry engineer but I'm pretty sure that coming up with an exact percentage for the perfect tail current is a rather complex issue, but has some flexibility built in. I think the 4% value is sort of a one size fits all number - not necessarily the absolute ideal percentage but close enough to work well for most people. I'm simply using average values, within the range of what Battle Born and Victron recommend; 4% is Victron's default value and it has worked well for me. Afterall, they've engineered these beasts, their products work and, personally, I' have no reason to second guess them.
