Does your unit come with lithium batteries, if not I would say no. I looked into them a few years back and decided that it was not my time to get into them. Charger was as much or more than one battery.
But the good side of Lithium is you can go from a 12 battery system down to just 4 batteries for us. The charger took up the space of 4 batteries. We were looking at a place in Phoenix, just don't remember the name right now.
Some reading for you.
