E-FAST 25A Battery Charger, 12/24V All in One Lifepo4 Lead Acid Car Battery Charger, Automotive Jump Starter, Upgraded Trickle Charger, Battery Maintainer for Car Truck Motorcycle Lawn Mower Boat

I purchased this charger primarily to charge lithium Ion phosphate batteries I have acquired over time. I hope to set up a solar array but have been using the batteries with out a solar set up. This does an excellent job! It is quiet and can charge a 50 amp hour battery in two hours at 25 amp rate.The first day i used this on starter battery In my old Jeep that was getting weak from sitting. The charger went right into desalination mode and ran for most the day. It brought the battery back to full life!The next day my Neighbor called me for help as she had left something on in her car and the battery was completely dead. The took the charger and set it to jump start mode. The first attempt was not enough but after the second jump start timed out, the car started with no problem. I have multiple battery chargers but none wth the Jump start feature which is really great to have!This is definitely a great charger! I hope it holds up! The only thing I wish it had was an amp hour meter to show how many amps you have charged to the battery.Also not really important is it displays temperature only in Celsius. However a simple method to get you close to Fahrenheit is double the number reading and add 30. All in all very pleased so far with this charger!

Wow. My wife was even impressed. Bought this for her as Christmas because her battery was always going dead. Recharges in TWO MINUTES! Gives readout of voltage and has a repair mode. Nice.

Been using this for awhile to charge up LiFe battery and it works GREAT. Can be set to 10A, 20A, 25A (but I wouldn't do highest). Can be set to normal lead acid, Gel, LiFe. Has battery charger protection if connected wrong. Nice little unit for LiFe battery Charging. One thing, ran battery down to 7v and had to jump it to car battery to increase it to 11v for the Charger to start charging it.

Bought this to replace an old heavy bulky charger with some doubt it would work as well. Finally had the dreaded dead battery and pulled it out. Not exactly intuitive but did the job correctly and automatically and the battery came back to life. Didn’t notify me it had completed its cycle, but the results were fine.You. Need some time to understand the various symbols and programs, but actually worked great.Owner,s manual not that great but the charger itself works very well. One star off for the lack of clear instructions and explanation of the various icons. Still not sure what actually is going on when…

As soon as I got it I put it to the test, plugged in and hooked up the life-po4 battery and an amazing 2.5 hours it was gully charged. It's a great product 👌

Lite weight, fits easily under the hood if you need to leave and trickle your battery

This smart charger is fooled by cold batteries into spending more time alarming about a possible faulty battery than trying to put a charge on it. The southern states should have no problem but forget it in Minnesota. They need to update this thing with a cold weather alarm override button or somehow make it smarter.My better choice will be a short but HEAVY duty jumper cable set because my good LONG HEAVY duty cables stay in a different vehicle to help out when someone needs them. With a short but good cable I could then always use one if my power outage batteries to jump something in my driveway if my main squeeze is away.

I got me a Lifep04 Battery, and this thing helped me revive it and charge it to full. Easy win.
