You Don’t Need Lithium for Camping… But I Tested AGM vs Lithium Under Real Load...

G'day I'm Cahn and in this video I am comparing three different batteries - they'll all run a typical camping fridge for a typical weekend away... but then why do so many people say to just get a lithium battery!? Do you actually need it? In this video I test AGM vs Lithium batteries in a real camping-style setup using actual loads... not just lab numbers. I run a 120Ah AGM, a 60Ah lithium and a 120Ah lithium through: A standard C20 discharge test (what the ratings are based on) and THEN compare those results to a real world test with a fridge cycling on and off and 30 minutes of high power draw to simulate an air fryer or induction cooktop. What becomes obvious is that battery performance isn’t just about Ah ratings on the label... Because under higher loads, AGM batteries behave very differently, voltage drops faster, usable capacity changes, and performance can feel completely different compared to lithium. Meanwhile lithium stays far more stable under the same conditions, even when the total stored energy is similar on paper. So the real question isn’t just “how big is your battery?” It’s: how much of that energy is actually usable in real camping use? This isn’t a perfect lab test... it’s a real-world system test with cycling loads, inverter spikes, and typical camping usage patterns. If you've got lower power loads and you're on a budget maybe an AGM is fine, otherwise... a lithium iron phosphate is likely the better choice! Cheers, Cahn
