Two 100AH 12V AGMs from Sams Club will yield 200AHs for $360(2 x $180), or about half the cost.
AGMs do not require a multistage charger, and certainly NOT a 4 stage. Stage 4 is usually a high voltage stage designed for flooded batteries to stir the liquid. AGM's acid does not stratify and actually cannot be stirred.
AGMs do benefit from a charger that monitors the battery temperature. This precludes the use of inappropriate high Voltages which may harm the AGM.
Look at the Parallax Powermode charger for around $175.

actually the lifeline is rated at 220ah each for ~$290,
but as i was browsing, i found the trojan t105 flooded deep cycle,
there are quite some good words about them, the best part is they are 225ah and $140 each.
since there isn't really a capacity or performance difference with agm and flooded, i may go with flooded after all.
for the charger part, i always thought agm needs special charger, since starting batteries are also flooded and not stage charged.
so you are saying if i get agm i can wire them to the starting battery simply using an isolator and let the alternator charge it, but if i get flooded i will need stage charger?
