You get two batteries. In full charge, it's going to have about a 20 minute charge for both. With the right blade or blades, you can take out a few feet of Bollards with it. I could cut a man sized crawl hole in about 15 seconds. If you can't, you must be one hell of a waste as a handyman. Go back to peddling those girl scout cookies and let real men do the real jobs.
They also make a compound blade which is what you would use. But don't use any of the blades from where you buy the saw. They are crap. Go to a reputable tool shop and buy a few good ones. Like the drill bits at Harbor Freight, the blades are crap as well.
I build electric vehicles from scratch. So I use one on a daily basis. And the metal I use is at least as strong as what is used in those security borders. In fact, when I get finished welding, heating, cooling, and more my metal is probably much stronger. My saw has no problem cutting through this metal at all. My metal is so strong that I go through a whole bunch of drill bits. So, I do know what I am talking about. Now, about those Cookies you sell. Please put me down for the Chocolate Covered Mints. I'll take 4 boxes.
I had to remove some posts that were metal filled with cement. I cut the metal around the pole away using a Blow Torch and then kicked the pole with a forward snap kick. I had to make sure I dialed up the proper pressure though and didn't exert enough the first kick. On the second kick, the pole came down. I ruined my left cowboy boot. Blew the heel halfway off. Of course, a 20lb sledge would have worked better and wouldn't have cost me a new pair of Justines. Or I could do the same job today using the power saw I pictured with a good quality compound blade much faster. In case you are wondering, a Compound Blade is a mixture of teeth from both the bimetal blade and the Concrete Blade. Or it might be not as fine as one but more course than the other. It's not going to last very long. But it doesn't have to last very long. Just long enough for the job. This ain't Rocket Science, Bucky.
