20 Amp Lithium Battery Charger, 12V And 24V Lifepo4 Lead-Acid AGM/Gel/SLA Portable Car Battery Maintainer Trickle Charger Desulfator For Automotive Boat Motorcycle Review

This battery charger is pretty compact for its 10A charging battery. It charges a full depleted car battery in less than 2 hours. The noise level by the fan is not bothering me. The accessaries with cables and battery terminal clamps are pretty handy. In addition, it can charge and repair dead lead-acid batteries and works on a 12V battery of a toy car. Overall, I'm satisfied.

Fantastic battery charger. It charges both lithium ion batteries and lead acid batteries. The 20 amp charging mode really charges a battery fast. I purchased two chargers. I installed one charger on my portable power station. The second charger will be in my camper maintaining the batteries in the solar system. I made both charges removable so I can use them for other batteries. The pulse battery repair function is really useful and allowed me to refurbish several deep cycle boat and auto…

My old car charger stopped working and probably because that my battery is pretty large and connected to a Dodge Challenger. Went looking for a better one, needed high amperage and smart type where I found this one, really nice specs and decided to give it a try. I was not disappointed; this one work's great. First off, very easy to use. I just connect it up, set the type of battery and it does the rest. A few weeks ago, my battery died where i don't always drive this car much and my jumper…

I received my Haisito smart charger fairly quickly, and the first thing I did was to charge my Lead-Acid battery bank of 400 Amp hours which I would need to break down to individual batteries because of the size of bank and to get individual battery reading, not a problem. After plugging in and setting mode with charging amps. and type of battery, easy as that. This unit constantly flashes vital information such as volts, charging amps, battery /temp. and state of charge and AH with an active…

The 20 Amp charger was purchased mainly to charge as needed and otherwise maintain the Lifepo4 battery that is part of my solar array I have added to my SUV. Having the option to switch to and charge my vehicle battery was a big selling point. As I have tested it all is working as stated in the documentation. Looking forward to our first adventure to see how it holds up.

Using to top off lifepo4 solar battery. Have used daily for a month. Easy controls, slide switch for amp selection, push button for battery selection. Information screen shows battery voltage, amps charging, temperature, total amp hours. Alligator clips and wires seem to be good quality. First 3 weeks the fan was noisy when first turned on. It would quiet down after about 30 seconds to a minute. Now it always seems to run at a normal sound level. That it the reason for the 4 stars.

I wanted this charger to charge 2x 100AH LIFEPO4 batteries.The cables and clamps aren’t too bad. The battery cable is maybe around three feet long and the AC cable is around ten feet long. They also give you some battery lugs to replace the clamps if you want.When I hooked it up to my 24v batteries it did a test and then said the batteries were fully charged when they weren't. I then tried it on a lead acid battery and it charged it ok. I tried the lifepo4 battery again and it started charging…

Quiet operation, clear bright and visible screen, nice long power cord, buttons have good crisp feedback. So far it has worked very well. The wire on the charging cables is decent and the clips are fine. Comes with a set of terminal lugs. XT60 connector output is nice.The one and only negative I've found so far is the soldering job on the XT60 connector. Numerous wire strands didn't get soldered to the connector cups. Nothing a quick desolder can't fix.I wish this had a capacity charging…

This item is really easy to use, it has screen that you can read numbers. Also quickly and safety when I used it. The two cables are in good quality also.

I have not used it much so I can't speak to long term reliability. I hooked it up to both a Lithium Ion battery and a lead-acid and it did what it was supposed to do - and it is a really small package.

I ordered this charger and it arrived quickly. I was surprised at the performance and multiple battery types and voltages it worked on. It completely charged my batteries in a short time.

Keeps track of amp hours into the battery, works as it should, cooling fan starts out noisy but quiets down in a few minuets.

We order a few of these to have 1 in each of our cars, we have had them for almost a month and they work great, the battery lasted for a long time. Very compact to keep anywhere, and great price.

I've had the 20amp charger for about a month now and it works great! I've been using it on a 50ah and 100ah LifePO4 batteries and it just works. I'm able to drop the charging current down for the smaller battery which is nice. Terminal clips are nice and strong. I also like how it remembers the last settings I put in so I can just plug it in and start charging without worrying about messing up my battery.

Stopped working after only 2 months of use. That's my review! Retailer quickly sent a replacement, will update after further review.

I've switched over to a lithium house battery in the boat. This charger does what it's supposed to do. Charges battery fast. I do like the fact that the screen tells you the condition of the battery and the status of the charge. Would definitely recommend.

Being a good charger for my boat battery. It charges fast and is ok-ly quiet in my garage. It has a few modes on it for different types of charging and repairing. Generally good! Not sure if I can connect the several same types of batteries to charge at the same tho.

We use these for our business. They work great, especially for the price. We bought two. Currently charging a 55 ft yacht as we speak.

Do not buy this!The interior cooling fan whines continuously, it's irritatingly loud.The seller's support is non-existent. When told about the issue their response was "the fan is for cooling."Useless!

When I bought it, I thought it was a jump box but It Is NOT a jump box. I have to take out my car’s battery and plug into the wall at home. I found a video on YouTube explaining how it works. It’s pretty easy and I love it!
