We needed a new one for charging batteries. This one works as it should. Easy to set up and use for vehicle, mowers and ATV's. Good value for money. Works fantastic. Quick to charge. Simple to use. Seems sturdy and durable. Highly recommend!

This is the second one I've had it's a great charger automatically shuts off the text if it's 12 or 24 volt just a great product

I bought this not knowing what to expect as my old transformer-based car battery charger finally bit the dust, gave up the ghost, or rusted to oblivion, whichever term you prefer. All are accurate. I have waited to post as I like to know how well things work before actually reviewing anything. Concerning this charger, it does work. It does the job I bought it for. There are some things I do not like that prevent a five star, but are not serious enough to warrant a bad review of three star or less either. First, the cords are too short, forcing me to have the charger very close to the battery. Second, the clamps are a little small. This makes it hard to clamp effectively onto the battery terminals, though I have seen chargers with even smaller clamps. Third, I know the wires are "rated" for the amperage, but they do not look it. The gauge of wire used to connect the unit to the battery is barely big enough to handle the amperage load, which could lead to fast wire overheating and mechanical failure if the charger experienced an amperage surge for any reason.

In an effort to help my fellow tinkerers who are simply looking for a REAL Lithium-ion (Li-ion) charger, this is it. I know that it has other settings, but I was only concerned with Li-ion battery charging and this charger performed excellently. I needed a specific charger for a specific battery and this charger specifications were perfect. I spent hours looking for a dedicated Li-ion charger and there didn't seem to be any that absolutely claimed to do this well. I needed a specific amount of amperage, and this charger was again perfect. I started the charging with the battery at 11.91V DC and the charger applied 5.8 amps (I was real happy to see that) so at that point I realized that the "smart aspect" was probably accurate, it didn't start pounding 12 amps right off the bat (which I was prepared to instantly disconnect if I saw that). Amperage started appropriately dropping throughout the charging process at a rate that I thought was correct. The battery never got hot, and the charger stayed cool also. I monitored the charging process the whole time because the battery I was charging was new and unknown to me, and I didn't want to damage it. The charging cables and AC line are (in my opinion) extremely small and undersized but did not cause any problems nor did they get warm to the touch. I do not know how far the charging would have proceeded, I stopped it at 12.6V because this battery is a unique proprietary unit and I did not want to "experiment". LA, LiFePO4, Ni-cad, etc. chargers are easy to find (and I have plenty) but if you need a true Li-ion charger for a medium sized battery (mine was 13500mAh) this charger works great. Highly recommended.

Works great

es facil de usar

It's been a good charger. I use it on both 12v and 24v LiFoP4 batteries. It lasted 1 yr and 9 months. Today it gave a load bang and then let all the smoke out. Opened it and as expected found a blown cap, 47uF at 63V rating. I fully expect it to work again after I get a replacement cap. Well I installed the new Cap and also found 2 other parts that were not soldered correctly and not making contact. After installing the new cap and correcting the two bad solder connections I tested the charger. It will not charge, it's no good. I now do not recommend this device.

I gave this item 3 stars... Which is an average of 5 stars for ease of use and seems like generally a quality made product and 1 star for charging time. It was taking days to fully charge brand new AGM batteries. After taking 3 days to fully charge one new AGM battery from 50% to 100%, I went ahead and hooked up the battery charger to a second new AGM battery and it also took 3 days to fully charge. In the meantime, I ordered a different smart charger and it fully charged two other brand new AGM batteries from 50% to 100% in about 20 minutes total time for both batteries! This battery charger is very easy to use, so I'm certain it was hooked correctly, with AGM battery selected, but took 6 days to charge two brand new AGM batteries... So I wouldn't recommend this battery charger unless you had plenty of time to charge your batteries. It did eventually fully charge two new AGM batteries, just took 3 days each battery.

Excelente

Es un cargador que realiza lavados carga de forma lenta, aprox. 12 horas para una carga total. Equipo que si cumplió con su objetivo.

No para automáticamente. Por lo menos con las baterías AGM por tal motivo las daña.
