LiTime Lithium Battery Charger 14.6V 40A, Special for 12V LiFePO4 Battery, with Display Instruction and LED Indicator, AC-DC Smart Charger for 12.8V LiFePO4 Lithium Batteries, 40A Fast Charging

Charges at 40 amps as advertised, it is pretty quiet and it hasn’t broken yet so I can’t complain, so far it’s been charging for probably 10+ hours and no problems.

Excellent

All in all I am happy with this battery charger. I plan on installing it in our boat to top off the 400Ahr of Life4po batteries we will be installing in the next few months. To perform a test, I used it to charge a single new 100Ahr life4po battery. I connected the charger to the battery with the supplied wiring and started a charging cycle. The charger indicated that it was putting out 40A to the battery. A clamp amp meter at the battery indicated it was only receiving 39A. I understand the clamp amp meter may not be the most accurate, but that is what it showed. After a couple of hours I checked the charger and discovered the wires from the charger to the battery were quite warm. Warmer than I would have expected. Looking at the wiring, the wires are marked as 6mm2, which is roughly 10AWG. This wire size is rated for approximately 32A. So the 40A output of the charger is a bit more than the wire is rated for. This could also explain the amperage loss between what the charger says and the clamp amp meter. Not a deal breaker, but for an almost $200 charger, you would think they would use larger enough wire to minimize current loss and heat generation. In our case where the charger may be expected to deliver the rated charging current for 10+ hours, I am a bit concerned with heat generated by the under sized wires.

Like all li time products excellent buy and gets the job done.... it charged my batteries right up ...easy and fast

It works as advertised

Very good

I bought several chargers previously, none of which satisfied me. It was not because they did not work. Each one of them worked as intended, but every one of them had something I can complain about. I was quite frustrated because of this.My luck started to change, however, after I ventured to purchase a battery from this company, knowing that I was taking a risk given the fact that the batteries were produced in China and few of us know the company that well. But the price was unbeatable! As I figured, if I could use the battery for half of the time, I already made the money back. Surprisingly, the battery turned out to be fine. Then, I searched for a good charger. At that time, I wanted to have a 40A charger, but this company did not have one. So, I bought one from another company, which turned out to be a hassle. The wire was not even fully covered, and the charger got very hot.Recently, I saw this new product from this company. Knowing that its battery is fine, I am willing to give it another try. What a real pleasant surprise is that the charger is great! It is very well designed, with a safety function and led indicator. I like the fact that the company paid attention to the details, such as using the Anderson plug connectors. That makes the charging a lot easier and much safer because, in the past, the real concern for the charger with alligator clips is the accidental touching of the two poles. I did that a few times, and it was not pleasant. This time, I am so glad that this company, Ampere Time, has done something right. By the way, I am not someone who always gives positive reviews to products from Amazon (you may check on that for yourself), but I won’t hesitate to sing praises if I see something that I like. This is surely one of them.

perfect addition to my solar system, I highly recommend this charger
