I have a Magnum MS1212 2000w / 100A 12v inverter-charger in my motorhome. By batteries are a couple of drop-in 460Ah packs for a total capacity of 920Ah
I am trying to decide which charge profile to use with I am plugged into a full hookup site. I have two programable profiles that should work for my PFL.

- Three phase - bulk, absorb float - use 13.8v for bulk and absorb with 30-minute absorb time and then drop to 13.4v float. In this profile the batteries will be held constantly at 13.4v and all service loads will be provided by the Magnum charger.
- Silent - bulk, absorb, off - charge pack to 13.8v for bulk and absorb with 30-minute absorb time and then turn off all charging until pack voltage drops to the customizable "re-bulk" voltage. In this profile the batteries will be held charged to 13.8v and then all service loads will be provided by the battery which will drop down to re-bulk (thinking of somewhere around 12.2v) and then be recharged to repeat the cycle.
