Slimline Batteries

If you’re in need of a renewable power supply but only have limited space to work with, then a slimline battery is your solution. At KickAss, many of our AGM and lithium batteries come in compact slim or ultra-slim designs, perfect for installing behind the rear seats of dual cab utes, in caravans, or anywhere where space is tight. Our slimline batteries are all encased in durable ABS plastic, and will protect your vehicle or installation point from battery acid in the unlikely event of a battery spill or malfunction. The perfect solution for compact spots.
