Awesome fast charging for my two battery banks! Price is reasonable and it does the job! It is compatible with my 12 volts battery bank and also works with 24 volts battery bank. This charger can do 2 amps slow maintenance mode and quick charging at 10amps—plenty of power to charge my battery banks! The build seems solid! Easy to use and to cycle between modes. Just keep pressing the mode button to select charging amp power. Note: the 24 volts battery bank is for my modified UPS for my network equipment (see last pic) The other 12 volts battery bank is for my power inverter! Runs my heating during power outage. This works great for I need it to do. The LED readout is nice and bright. Easy to see!

This charger works as advertised. It recognizes the battery voltage and does a beautiful job of charging the battery. It is well worth the money. I recommend it.

First let me say I have been looking for the right charger, that is durable enough, and with 24 volt capabilities, for more than a year now. I have BattleBorn Batteries which are the gold standard of LifePO4 batteries on the market, for my off grid Solar System. These batteries are a very expensive investment worth protecting.To protect these batteries, and the Solar Controller that charges them, we developed a simple circuit to switch on 110v power to activate a charger, to keep the batteries from ever reaching the Battery Management Systems low voltage cutoff point, which can happen after several rainy days.This is so important with an off grid system that uses an MPPT Solar Charge Controller like ours. Our controller cost right at a thousand dollars, and one peculiarity of the MPPT charge controller is that it can be destroyed if the battery load is disconnected while the panels are still connected. So allowing our LifePO4 batteries to discharge too low is a real bad thing! (Don't ask me how I know, OUCH!!)Our biggest problem in developing our failsafe system was in finding a high quality charger that could take up the slack on days when the voltage went too low, and keep a bank of three BattleBorn LifePO4, 24 volt batteries from dropping so low they trigger the disconnect feature built into the batteries.This is not a job for just just any charger. As you can see we are asking so much more of this charger than most users ever would.But this charger handles the job very well. It is a quality piece of equipment.One of the most wonderful things about this charger is that once you configure it to the settings you like, it holds that setting even after the unit is turned off. A lot of electronic smart charges do not, and you have to run through their entire menu all over, every time they are powered up, making them unsuitable for my monitoring device, or any other remote device, like a timer, that switches 110v power to the charger when it is needed, and then turns the power off when it's not. But this charger is well designed enough that it holds its settings when powered off, and it comes right back on when power is restored.Another notable feature of this device is how easy it is to see the display, I can view the state of things from halfway across a room. And maybe best of all is the very simple menu. It not only allows you to easily select your battery type, voltage, and the current of your choice, but it then displays a very easy to understand state of charge while in use. This is one fantastic device for the price. I have other much more expensive chargers that have now become my second choice since adding this to our shop.

Charger works well and I have charged both 12 and 24V lifepo4's. I give it 4 stars instead of 5 for one reason. I'd like to give it a 4.9 but one small change I'd like to see. The unit tracks and displays the amount of energy delivered to the battery while it is charging, but when the battery is fully charged, the display switches to FULL and total energy delivered information is lost. I am not going to try to watch the unit until right before it changes to FULL. Can you scroll FULL/ energy delivered until it is unplugged either at the ac side or battery cable side?

Great compact style charger with all the functions for charging a variety of battery types, including lithium. Easy to use, easily read digital screen. Very excellent value. Charges fast if needed, slow if trickle charging. Easy instructions included.

Love this thing. Works great and knows how much to charge.

It works, I don't know what else I could want to do. I use it to charge a fishing battery and it charges it and shuts off. It's probably got 100 cycles on it.

Happy with this charger purchase . Product is well built and worked as it should right out of the box. I have charged my 24 volt lifepo4 and my 12v agm batteries with no issues . Very easy to use . I would Definitely recommend this product.
