Q. I have a Xantrex 458 2000 watts. Do I set it to overheat AGM for lithium ion batteries?

A. Several of the Li battery makers recommend AGM setting for their batteries. The Freedom 458 is not designed to charge lithium ion batteries. It may not hurt setting to AGM setting but it probably won’t fully top up either. The best option is to upgrade to a lithium ion compatible inverter/charger such as the Freedom XC or Freedom SW.
