KickAss 12V 120Ah Lithium Battery Bundle with 22Amp Charger & Tray

When space is tight but power demands are high, the KickAss 12V 120Ah Lithium Slimline Deep Cycle Battery LiFePO4 is built to deliver. Designed to fit into narrow compartments and tight installations where a standard deep cycle battery simply won’t fit, this battery is ideal for caravans, camper trailers, 4WDs, boats, and off-grid solar setups. It’s also an ideal drop-in replacement if you have an older slimline battery that’s ready for an upgrade.

At its core is a set of high-quality, A-grade prismatic LiFePO4 cells, delivering 120Ah of usable capacity and 120A of continuous charge and discharge current. That means reliable, consistent power for fridges, lighting, inverters, and other 12V accessories, whether you're camping for a weekend or living off-grid for weeks at a time.

Rated for 4000 cycles at 80% depth of discharge, this lithium deep cycle battery is built to outlast traditional AGM and lead-acid batteries many times over, offering better long-term value for caravan, camping, marine, and solar battery setups.

Safety and reliability are built in from the ground up. An intelligent Battery Management System (BMS) continuously monitors the battery, helping protect against overheating, overcharging, overdischarging, short circuits, and voltage irregularities. Combined with an IP65-rated housing for dust and water protection, this battery is built to handle harsh Australian conditions, from dusty outback tracks to salty marine environments.

Low self-discharge means this battery holds its charge well during storage, so it's ready to go when you are, even after weeks sitting idle. A wide operating temperature range – charging from -10°C to 60°C and discharging from -20°C to 65°C – ensures dependable performance across the seasons, whether you're chasing summer swells or exploring in the depths of winter.

Compact, powerful, and built for Australian conditions, the KickAss 12V 120Ah Lithium Slimline Deep Cycle Battery is the ideal upgrade for anyone after a reliable, long-lasting lithium battery that fits where others can't.
