This is a very nice battery charger/ maintainer. Definitely built heavy duty to last. I think it is the perfect size for our rv. Charges our LifePo4 batteries quickly and safely and keeps them topped off. And you know, the price is not more expensive than any other quality battery charger. And so simple to set up and use.

Man this thing is big but it fit and it is awesome I hope that up it recognized that they were lithium batteries on its own and we will see time will tell so far it seems really well made. But like I said time will tell I will be back in a year or two with the Good The Bad and hopefully not ugly lol.

I have an older full sized SUV with a parasitic draw. Can't get the parts anymore to fix it so if it sits for more than 2 or 3 days (weather makes a difference) the battery gets to low to start her. I put a quick plug in on the battery, and run this all weather charger in the wheel weld (to shield the lcd from sunlight.) It delivers up to 5 AMPS, so never have problem getting my ride started. I used to leave it on the hood, and the weather NEVER bothered the operation.

This charges my trolling motor batteries in just a few hours. I run three lithium batteries and after a full day offshore they are charged and ready to go again in about 3 to 4 hours. It was easy to mount and hook up. and its not so expensive as other brands. Everything worked right away with no issues. It fits well in my setup and does not take up much space. Overall it has worked perfect for what I needed.

I have multiple CTEK units along with the usual handful of Battery Tenders. The 3-bank unit seems constructed well, easy to grasp panel with modes/LED charging level. I have it connected to dual batteries in my boat, that is garage kept so no idea on how it fares outdoors, waterproofness, etc.. I've had it connected for approximately 3 months with no problem. If I had, or if they made, an SAE to CTEK-type Comfort Connector - I'd also connect my BMW GS-A battery to the 3rd bank!
