Campervan Battery Kits
Reliable lithium battery systems sized for your adventures. From weekend getaways to full-time van life, find the power setup that keeps you off-grid.
4.9 stars · 150+ reviewsChoosing the right battery is the most important decision in your build
Get it wrong and you're either running out of power on day two or spending twice what you needed to. Lithium vs AGM, 100Ah vs 200Ah, parallel vs series — it's a lot to figure out when you just want to power some lights and charge your phone.
The specs don't help either. Amp-hours, C-ratings, depth of discharge — most product pages are written for engineers, not van builders. You end up guessing, or buying what a stranger on a forum recommended for a completely different van.
Your battery system needs to match your actual usage, your charging setup, and your van. There's no one-size-fits-all answer, but there is a right answer for you.
That's why we built a tool that works it out for you — based on your appliances, your charging, and how long you want to stay off-grid.
