Three batteries. One charger. No more juggling cables or leaving a wall socket occupied for the weekend. The Blue Smart IP22 12/20-3 handles up to three 12V batteries on a single unit — three positive screw terminals, one common negative. Lead Acid or Lithium, it sorts the charge profile automatically. Bluetooth means you check state-of-charge from your phone in the yard without crawling under the workbench. It's rated for 230V AU/NZ mains, so no hunting for a transformer. If you've got a workshop with a forklift, a ute battery, and a marine bank all needing a top-up, this one unit covers it. Set it, forget it, check it from your phone when you want
