You can do that. You would need to check the mnfg specs but often times an agm will want a Max voltage of 14.4. A wet cell like a Trojan will need 14.8 volts.

Often times a oem converter will only put out 13.6 v so upgrading to something like a progressive dynamics may work well. I wouldn't buy an wfco.

You could have very long generator run time with only 13.6 vs 14.4. when the battery is charged it will cut back to about 13.2
