Technical specs LiFeP04 lithium batteries, voltage output
Just got it, seems to work fine. Writing this review to provide info I couldn’t find when looking for a charging and trickle charging solution for EBL brand Lithium LiFeP04 EBL brand motorcycle battery. Here are pics from the manual. Comes with SAE quick connection. (@Mroinge, could you please provide this in your product description. LiFeP04 need to know max voltage and what’s happens in float mode in order to care for the life of the battery. Ideally, when the battery is full, the charger checks it periodically and charges accordingly. This is different than a float mode. It would be a monitor and maintenance mode. Thanks)

Great Trickle Battery Charger
It is what it states. A trickle charger, which is what I wanted for my lithium battery that I use for my fish locater on my boat. The charging rate is as stated and I like the automatic shut off feature. Works great for what I wanted it for. Compact size Etc.

So Far So Good!
An economical charger that does charge lithium small batteries. I'm not sure I would buy it for car batteries. Or larger vehicle batteries or golf carts, etc. But if you have. E Bikes. Small generator batteries. Or small ATV batteries. Yes, it does the job. For the price, a good buy.

Decent battery tender
Got this to leave connected as a battery tender for my tractor. The build quality is ok. Cables are excellent but the transformer it's self is very lightweight and doesn't have a quality feel to it. It works ok but I'm not sure I'm ready to trust it connected to my battery 24/7. At this point I have the ring connectors attached to the battery to simplify charging when needed. The quick connect makes it easy to use and the wire comes with connection protection.

It DOES work on lirhium batteries
Did not know that I needed a different charger when I switched to the lithium battery. When I pulled it from my bike this past Winter, I had it on the standard trickle charger as I always did my previous ones. Excited as always to go for that first ride when the there's a really nice day, I dropped the battery back in the bike. She started ok, went for a nice little ride, and that was that. Parked and couldn't wait for another tease of nice weather. Got it sooner than expected and couldn't get on the bike fast enough! Um.....nothing. No turnover, no lights, just silence. Wtf did i do? Is something loose? Did something else drain the battery? Took my bike apart, checked everything while putting the battery back on the regular charger (which after just a short time showed fully charged). Tried again, still no start, nada, nothing... Well, bummer. I'm thinking I killed a new battery and have my bike parts all over the driveway, too, now. If you can't figure it out and are too stubborn to go to a mechanic like me (because, ladies, you KNOW they try to take advantage of us), you call your riding kids/brothers or go to the School of YouTube. Wow, really? Yeah, now I DO feel stupid....a battery tender made for lithium batteries because regular chargers don't have enough voltage. With this battery charger, you CAN do both! It will charge your regular battery but ups the voltage for your lithium batteries! Win Win! Go ride that vehicle!

Great
I own four of these for lead acid battery’s. They are great. Good bang for buck. They really shine when you use them for small 22 amp hour or less battery’s. You can use them for a charger for smaller battery’s. They allow you to get maximum life out of your battery’s.

It worked fine.
Tried it yesterday on my old computer running linux mint. It worked fine.

Solid Little Battery "Tender"/Maintainer for My Harley Ultra Classic (Lithium Battery)
This seller is very responsive to questions and solutions when needed. Shipment and arrival were quick, and I appreciated this seller's quick answers and suggestions I asked for - during the course of a weekend, even! One of my concerns was whether or not this unit would get hot trying to top off and keep charged this larger-than-some lithium battery. My battery is a recently acquired "Weize Lithium YTX30L-BS, 700CCA Lithium LiFePO4 YTX30L Motorcycle Battery, 12V 10AH". This charger hasn't gotten hot doing its job, as some reviewers reported. I did have an issue with this charger completely turning off after going past the "80% charged" indication (blinking green light). For the most part, the solution to this is unplugging the charger from power and plugging it back in. The seller was very helpful when I encountered this. Vs a 90-dollar Battery Tender brand that is also designed for use with lithium batteries, this unit is a great option for light charging and maintaining your battery. I don't know how well it will do to bring up a badly discharged battery at this point. I've only used it for about a week now, and if this unit craps out on me, I'll update/amend this review, but so far, so good!

I use this product to keep the battery charged in my truck, as it is not used very often since my retirement. It works very well, as the battery has not failed to start the vehicle since I installed the maintainer.

Yes I assumed this would work on 230v. Yes I didn't read carefully enough. It blew up as soon as I plugged it in.

Popped as soon as I plugged it in and obviously now doesn't work

I feel much safer charging LiFePo in my apartment, and most good quality batteries are pretty safe but only with a proper charger! It was an e bike that set a hotel in Vancouver's east end causing a couple deaths, leaving some vulnerable people without a home as well. This is the proper charger for these batteries .I hate it when my things catch fire, cannabis excepted. And not everyone can afford insurance, but that is what this feels like to me. Insurance.

Because the charger is compact and simple to understand its operation, I have given the features 5 stars. However, because I have not yet used the charger, I have only given it a 4 star rating because I don't know how it will perform when I put it into service, although I expect it will do the job as promised.
