Battery Bank - wire for 12v, 24v, or 48v?
I have four 12v 100Ah Battle Born lithium drop-ins. I'm looking towards the future using Victron components: - 3,000W inverter w/ hybrid load-support - solar charging Currently I have a built-in ...

Yes, I made all the adjustments to the Victron (Peukert, etc) based on the battery manufacturer's recommendations, but it's still not accurate. We're not talking a small discrepancy, more like the BMV shows 83% charge (with voltage at 13.2?) vs 98% on the BMS panel. And this after a full charge the day before - sitting in driveway hooked up to shore power.
Samlex gave me instructions on how to set up the inverter charger (3012) as a 2 stage charger to allow the batteries to trickle down (via parasitic draws) to 80% and then kick in charger to boost back up to 100% - this all based on the idea that it's not good to keep lithium batteries at 100% SOC for long periods of time. I surely have a setting wrong somewhere, just haven't had time to drill down into it.
