You upgraded to lithium for better performance - don't let a dead battery stop you. If it sat too long or drained from heavy use, this battery charger brings it back to life. It safely restores, charges, and maintains 12V LiFePO4 batteries.
If you've made the jump to lithium - especially for your RV, overland rig, or off-grid setup - you already know they charge differently, and they need a charger that knows how to handle it. The CTEK Lithium US is built specifically for 12V LiFePO batteries, delivering the right voltage and charge profile for performance, protection, and peace of mind. No more guessing if your old lead-acid charger is close enough - this one was made for the job.
Lithium batteries with under-voltage protection (UVP) can completely shut off when deeply discharged. This charger doesn't panic when that happens - it knows exactly what to do. It automatically resets the protection circuit and brings your battery back online. And if that doesn't work? Just press the RESET button for 10 seconds to manually wake it up. You'll be sure the charger can handle the situation when your battery can't. It's a must-have feature for stored vehicles that can sit for months.
With 4.3 amps of output, this charger restores power quickly without taking shortcuts. It's fast enough to get your battery back in action, but smart enough to do it safely. The multi-stage charging profile is tuned specifically for lithium, balancing efficiency with long-term battery health. Quick enough to be convenient, smart enough to be safe.
This isn't a one-step charge-and-done device. Once you connect the charger, the 8-step charging cycle tests, maximizes, and safely maintains your battery. It handles bulk charging, voltage stabilization, and long-term maintenance automatically - all while keeping your battery topped off and ready. And you can leave it connected for days or weeks. It'll maintain the charge without overdoing it. You get a complete cycle every time, without needing to monitor a thing.
You don't have to stress about making a mistake here. This charger is spark-proof, reverse polarity protected, and short-circuit safe, so even if you fumble the clamps, nothing bad happens. It's also IP65 rated, meaning it stands up to dust and water spray - ready for garages, sheds, or wherever you stash your gear.

Hi, everyone, Steve here with etrailer.com. Today, we're looking together at our CTEK Lithium US Smart Battery Charger with an AC to DC 12 volt option. Folks, this is made for lithium batteries. It's going to optimize charging, and it's gonna maximize the battery performance and lifespan. Now, this can wake up batteries from storage, it's gonna reset the low voltage protection, and it's gonna recover batteries after months and months of inactivity. So you can also keep this plugged in to keep it up to date while it's winter time or while it's in storage, as long as you have a plug nearby to do so.
You're gonna get some alligator-style clips as I call them. You're gonna get inline fuse. You're gonna have that connector, which is gonna match up with this connector right here. And you're also gonna have an option here with an inline fuse to then mount directly to the battery without terminals if you so choose. You also get a nice storage bag here.
As you can see, it's got pictures of how you can connect everything as well. Now, this is a fully-automatic operation, so it's got a built-in maintenance mode. Like I said, if you left it plugged in, if you had this permanently installed and just plugged in, it's gonna do its thing automatically. So whether it's in the garage, in the storage shed, or whatnot, this is gonna keep working through exposure to dust, moisture, all that. So use a smart technology.
Very nice product. If you've ever seen any of the other CTEK things that we carry here, very nice products as well. This is just a new version here that does the lithium batteries as well. So pretty impressed with it. Again, folks, it's got lots of specs on it.
You can check them out here on the website as well here on the product page. That's gonna wrap it up. I'm Steven, as always, we'd love to hear your feedback on the product. Let us know how you're using it, where you're using it, and send us some photos. Have a good one.
