What kind of free spirit are you?
Seven quick questions, 90 seconds. Find your free spirit, then a power setup to match.
Answers before you ask.
Three questions size any system: what will you be powering, how long do you need to run it without the engine or shore power, and how will you recharge. Answer those three in our Power Guide and it will point you to a right-sized system, or send them to us for a free system review.
If you are building or upgrading a system, start with a kit: every component is selected to work together, with correct voltages and charge profiles; we give you the fuse and cable sizes, and those parts are bought separately. Individual parts are best when you are replacing a known component. All parts remain available individually.
Lithium gives roughly twice the usable capacity per rated amp-hour, charges faster, weighs about half as much and lasts 3,000+ cycles, but costs more up front and needs lithium-compatible charging. AGM costs less and tolerates cold charging better. For most RV, van and marine house banks we recommend lithium, and we will tell you honestly when AGM is the better fit.
Yes, that is the point of our kits. Every kit is specced by our engineers so chemistry, charge profiles, voltages and protection match, and our pros can review your setup for free before you order if you like.
Yes, with a DC-DC charger sized to your alternator, or a high-output alternator with a smart external regulator for faster charging. Never connect lithium directly to a stock alternator; uncontrolled charging can overheat it. This is one of the most common mistakes we fix.
Sometimes, and we will tell you plainly when you cannot. Heavy loads like A/C need a large battery bank and inverter; running A/C full-time on a small system is not realistic, and we will not sell you a setup that pretends otherwise. Tell us the load and runtime you want and we will spec what it actually takes.
