Lithium-ion pros: Lightweight (half AGM weight), full power till dead, longer life. Cons: Pricey ($800+) & temp-sensitive. Future-proof, but AGM's fine for now.
AGM (Absorbed Glass Mat) batteries: My go-to for most rigs. Quick charge, deep discharge without damage. 100-120Ah in a Group 31 size runs a fridge for days. Balanced cost & performance.
Vehicle battery basics: Lead acid is cheap & great for starting engines, but not for long draws like fridges. it'll die fast. Skip for aux power in your rig.
Hybrid option for vehicle electrical: Mount charger under hood, battery in back. Flexible for SUVs or vans. We've got @NationalLuna solutions to fit. Save interior space for gear.
Where to mount your aux battery? Under the hood if space allows—short wires mean less voltage drop & better charging. No room? Back of SUV or truck bed works great. Pro tip: Keep it close to the main battery for efficiency.
For advanced vehicle electrical setups, permanent installs rock: Charge via alternator + solar. @NationalLuna is my choice for top-tier systems. Build for your needs, not excess.
Not ready for a full electrical overhaul? Start simple: Portable battery for weekend fridge runs, charged at home or via solar. No vehicle mods needed! Low cost, big adventure.
Choosing your vehicle is key! SUV for outside living or Sprinter van for indoor setup? Space dictates your electrical needs—like battery size for fridges & lights. Think inside vs. outside living upfront.
First step in your overland electrical build? Define your goals! Weekend trips with the fam? Full-time van life? Or globe-trotting? Your goals shape everything—from batteries to charging. What's yours?
