25 Amp Lithium Battery Charger, 12V and 24V Lifepo4,Lead-Acid(AGM/Gel/SLA..) Battery Charger,Battery Maintainer, Trickle Charger, and Battery Desulfator for Car,Boat,Motorcycle, Lawn Mower.

Great charger. Works as it should and the rejuvenate feature really restores older batteries for longer life. Automatic voltage detection is a plus.

Charger works great, I have a golf cart with three lithium batteries and was having issues with charging. This charger did the job.

Please heed all the reviews that tell you that this is a 20 AMP charger. The maximum amperage output on these chargers is 20 nominal amps, which means you'll see pean amps of 19+. This is appears to be some kind of design limitation in all the chargers that look like this, as reviewers for all of them all state the same: the max you get from this model is 19-19.9 amps, though its labeled as 25 amp max. But the charger does work. It automatically identifies your battery type, and adjusts its settings accordingly. It has 3 modes of operation from which to choose: 33% = 2amp max, 66% = 15 amp max, and 100% = 20 amp max. When it's running, the fan is SUPER noisy. The chargers has 9 stages which, if you already know how electric charging stages work, you will see that this charger indeed works properly. It does the job... but it does it at 20AMP. Tis is a good price for a 20AMP charger, comparatively, and I suspect he chargers of this model type labeled as 20AMP max, are likely less than that as well. Otherwise, just buy one of those. The false advertising cost it a STAR for me.

Powerful, Compact, Smart. It works really well. The charging rat of up to 25A is awesome. It only runs about 19.5 into my 100AH of LiFePo4 batteries. So, dead to full in about 5 hours. I use 50A anderson connectors in my distribution for my 12V stuff like my fridge, inverter, and starlink. So i got an XT60 pigtail and it suits my needs perfectly.I will say the power cord seems for be too thin for 250-300W from the wall. I had a high quality one to substitute. Thats the only weakness i see.

I have gone through a variety of chargers, including brand names such as Biuenno and they have consistently failed to properly charge and maintain my LifePo4 batteries. They let those batteries drift down to 12.8 volts and still did not recharge them. Not this charger! Hook up a LifePo4 and this charger goes to work! Charges them until they are 13.8 volts (where they belong) and then maintains them. Excellent. Requires no manual intervention. Hook up the battery and it goes to work. Excellent highly informative display. Now, the little fan is noisy. You would not want these in your house. Best keep the batteries and the charger in the garage. It uses 9-step charging and maintenance. My LifePo4s are happy!

I have tried this on the lithium iron battery and I have never seen it get to 25 amp. It only charged the battery about 25 % and said full charge. Not sure about it for lithium batteries. It worked great on restoring a lead acid deep cycle battery. So I would say it’s just ok.

Install in small camper build to charge 200Ah of Li batteries from shore power when plugged in and has worked fine for a good while now. Quiet fan when in operation. Monitors battery charge level when in use. several charge level options. Good value for $$ so far.

The most I saw from this was 18 amps. Nowhere near the 25 advertised. It quit charging at 83% charge on my 100ah lifepo4 battery, the same place my old charger for flooded/agm/sla shut off. Fan is crazy loud.
