Review on 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 by Lorenzo Wood

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 this time so I don't know what the weirdness the first time was all about. It went to 10A and charged and as it went on the current dropped to 8A after a few minutes. It charged my battery to 28.2v and stopped. So it seems to have worked ok that time.In use, the fan runs, and I would say the noise from it is minimal but just keep in mind it isn’t silent if that matters to you.I don't like how fast the information on the screen cycles from one thing to the next. Another thing that I don't like is the controls on the charger. The power selector switch is just a tiny exposed switch and the mode selector is a touch button. I would have liked a more robust selector switch and a physical momentary button switch for the mode.I did have that weirdness with the lifepo4 that one time so time will tell how things pan out overall. If I have other problems or issues I will be sure to come back and update this review. Right now overall I feel that this is an OK charger.Update 9/5/22: The fan is already going bad, it squeals.
