⚖️

Lithium vs AGM

Lithium is lighter, gives ~100% usable capacity, charges faster and lasts far longer — best for regular use. AGM costs less upfront and is proven for lighter or backup duty.

📏

Size it right

Match capacity to your daily draw. With lithium you can use nearly all the rated Ah; with AGM, plan around ~50% usable to protect its life.

🔌

Charging matters

Lithium needs a lithium-profile charger or DC-DC and pairs beautifully with solar. AGM works with standard chargers. We'll set the right charging for your setup.

Where it's used

Caravans, camper trailers, 4WDs, boat house banks and off-grid solar. Tell us your rig and we'll match the right chemistry and size.
