Works exactly like it should. The 20 amp feature is great! It is a little noisy though. It auto senses your battery so you dont have to select what charge mode. Great product.

Works great. Nice to be able to charge 24 volt instead of doing one 12 volt battery at a time.

I bought two of these units on a leap of faith that they would perform according to their spec. Well, the important stuff does! Here's what I like about the 20 AMP PRO MAX units that I bought:1. It does a good job of charging a LiFePo battery bank to 14.4 volts as needed.2. It automatically detects the battery type. Didn't think I'd like this but it seems to do what it's supposed to do.3. It REMEMBERS it's settings if it loses power and resumes operation when power is restored. This is a HUGE benefit and really a necessity in my situation. The cheaper competitor unit I bought is being returned because it couldn't do this.Now for the "cons".1. Although it's set for an LiFePo battery, it never put out a full 20 amps of current. It folded back to 16 amps for most of the charge cycle and then cycled at lower currents at nearly full charge.Since the LiFePo batteries have built-in over-current and over-charging features in the form of a BMS unit, I wasn't concerned about the "nearly charged" behavior, but I am disappointed in the charger failing to provide maximum current at lower voltage readings. In fact, unless needed to protect the charger itself, I see no reason for it to limit output current on an LiFePo setting EVER. As I said; The built-in BMS handles this on that type of battery. So I'm dinging them one star because otherwise everything seems to work well and (almost) fits my needs.UPDATE on 8-2-2024OK; I've had two of these for a while now. I use them to provide backup power and refresh of a battery backup system that has three 200AH LiFePo batteries tied in parallel. It's for electronics backup power so it acts like a large UPS or if you prefer; a "stationary" RV application.So the problem is; the charger kept the batteries at 14.4v most of the time. Then it reported "FULL one day and I decided to see what would happen as the system discharged. Well; the system discharged completely and the charger never resumed charging on it's own. This is a huge disappointment.Now; the units seem to want to treat the LiFePo as a lead acid and it shows "FULL again at about 13.6v.I really wanted to like these and I was going to buy more but, I don't think the algorithm for "automatically" determining the battery type is reliable.

It works as intended but keep in mind that it will not work on a fully discharged battery.The battery must hold a little bit of charge so the charger can "know" what it is connected and proceed with the charge.
