Don't worry about it not being a 4 stage... it just means it gives the batts a blast at about 14.8v occasionally. It's not true equalizing, anyway. Keep the batts full on a regular basis, and don't let them sit in a discharged state, and they'll be fine. And full means FULL, not near full. List what batts you bought, and several here can tell you what they'll need for proper charging.
If they ever do require EQ'ing, do it right. Mexicowanderer has at least one thread dedicated to EQ'ing.
