Your correct that your 2006 IOTA converter/charger is a 2-stage unit....., I replaced my 2005 IOTA 2-stage a couple of years ago for Progressive Dynamics 4-stage unit to optimize the performance/life of my (2) 6V Deep Cycle CG batteries.
I have to believe that to maximize the performance of an AGM battery a 3 or 4-stage converter/charger is a must, the 2-stage unit IMO will compromise the performance and life.
With some IOTA converter/chargers you can add a IQ4 Smart Charger that plugs into the existing IOTA, the IQ4 will make it a 3-stage unit.

If your IOTA unit is mounted to the back of the Load Center (breaker/fuse panel) the IQ4 won't work (no plug-in port). If you have a remote free-standing IOTA unit then it has the required Dual Voltage plug-in port for the IQ4.
