From a compact 12V camping battery through to 24V, 36V marine, and 48V home backup, the range is handpicked for real trips, not just a spec sheet. New to lithium? Start with our guide to lithium battery voltage for camping.
What to Look for in K2 Battery Solutions
LiFePO4 cells and a built-in BMS
K2 batteries use Lithium Iron Phosphate with battery management built in. That is the difference between a battery that looks after charge and discharge, and one you have to babysit. Lighter than lead-acid, with more of the capacity actually usable on the trip.
Voltage that matches the job
12V K2 batteries suit caravans, campers, and 4WDs. Step up when the load does: 24V for heavier work, 36V for marine, and a 48V rack battery when the job is home solar or backup. Pair camping setups with camping inverters if you need 240V.
Capacity you will actually use
A 100Ah or 200Ah covers lighter weekends. Longer stays, or a fridge plus more 12V gear, usually point to 304Ah, the 314Ah solid-state, or 400Ah. If you are still comparing brands, see the wider lithium camping batteries range.
K2 Batteries for 12V, 24V, 36V and 48V Setups
12V K2 batteries
The backbone of most camping setups. Capacities include 100Ah, 200Ah, 304Ah, a 314Ah solid-state battery, and a 400Ah for fridges, lights, water pumps, and other 12V gear. The 100Ah includes an integrated Bluetooth BMS.
24V K2 battery solutions
The K2 Energy 24V 230Ah is the step up for heavier jobs. It stores 5,888Wh and supports fast charging up to 100A, which suits larger loads where a 12V bank would be working harder.
36V K2 batteries
The 36V 100Ah is built for marine use, including electric outboards and trolling motors, so you can stay on the water longer without a heavy lead-acid bank.
48V K2 battery solutions for home backup
The K2 Energy Pytes V5 is a 51.2V rack-mounted battery for home solar, backup power, and off-grid systems. It stores solar and keeps the essentials running. It is not a drop-in replacement for a small 12V camping battery.
Comparing brands? Have a look at iTechWorld batteries, Amptron batteries, Renogy batteries, Invicta batteries, or Custom lithium batteries.
