Lithium Lifepo4 Battery Charger,12V 24V AGM Deep Cycle Fully Automatic Car Battery Charger,12 Volt 24 Volt 20 amp Batetry Charger Automotive,Smart Trickle Charger

Had this for several months and used it several times on my RV, pick up truck and car. Works very well and so far holding up well. Very lightweight and easy to sit anywhere while charging. Very easy to use, just hook it up and it automatically starts charging. Happy with my purchase.

quick shipping and works great to fix and recharge multiple types of batteries!

I bought the Pro model because I want to charge at 20amp. It's a 20 amp charger. I contacted seller and they lied as to why it won't charge at 20amp. "15.7amps is where it will charge" I'm a retired electrician of 39 years and a certified solar installer. They tried to tell me the reason was that it would hurt the battery if charged at 20amp. The battery is literally rated to be charged at that rate not to mention has its own BMS that will protect itself. So it's just BS that it won't charge at the advertised current. Spend a Lil more and buy from someone that won't gaslight you and tell you BS so they can sell you a lesser product. And let's not forget, when I have it hooked up to an MPPT solar charge controller, I push 20amp in without issue, because it's literally rated for it. They put a BMS in the battery for a reason.

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.

Great Item, A Must have for many reasons... This charger will top of your lifepo4 batteries correctly to unlock their true potential ... Plus Just the other day My motorcycle battery was dead , 4+ year old battery, so its time... when I connected this charger the reading was.. full, yet no power to turn engine over... I pushed the repair button on this charger and walk away... checked on it the text morning and she spun over like new !!! Amazing !!!

Easy to use - works great on lithium and regular batteries.

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.

Great charger. Had to send first one back , something came lose in shipping.
