E-FASTBattery Charger, 10A Lifepo4 Lead Acid Car Battery Charger, Upgraded Automobile Trickle Charger 12/24V, All in 1 Battery Maintainer, for Truck Motorcycle AGM Lawn Mower Boat Marine Batteries

Wanted a cheap 24v Lifepo4 charger for two new lifepo4 batteries I have in a quad. This fit the bill. Cut off the alligator clamps and installed a SAE charger connector. It is definitely cheap, but it works well and hasn't let me down yet.

This was chosen for it's LiFe Lithium battery charging capabilities and it performs well. It's not the fastest charger on the market but you can feel comfortable setting it up and letting it do it's thing. I was a little surprised at it's low weight but it does what it's supposed to. It will let you know if it's wired incorrectly which is a bonus if you have a luxury vehicle with sensitive electronics. I didn't expect much considering the low price but now that I've used it, I am happy with it.

Bought it to specifically keep a 200ah lifepo4 battery topped off. Did a good job charging it up. Not much else I can say. Wish it was a little faster, but it did the job.

Works good for lithium. Doesn't seem to get extremely dead batteries charged.

With the new ATV battery we bought, my husband needed a special type of charger. This works great and was a wonderful buy. Very happy with this charger.

I used this to charge my LiFePo4 12.8V 50Ah battery that i had just discharged to about 15% of capacity. I'm giving this 4 stars as a preliminary rating, if it's still working as well after five recharges I'll bump it to 5 stars. [UPDATE 5/26/24 to raise rating to 5 stars; the charger continues to work exactly as desired.] The user manual only gets 3 stars, though. The writing is decent, but it's just not very informative, particularly about LiFePo4 charging and what all those light are doing.The Charging:Plugged it in, tapped the mode button to set it to LiFePo4, and attached the clamps. The charger correctly identified the battery as 12V and chargeable, and got to work. About 6 hours later it turned itself off. Open-circuit voltage after 3 hours of rest is a comfy 13.4 volts, and most state of charge tables give that a 99%. What's not to like?The charger got only a little warm, and emitted no overheated electronics or baking plastic odors . Cables and connectors all stayed cool. The fan makes a pleasant hum. Some reviewers find the case to be kind of a little to plasticky, but it seems solid enough to me.Starting the charging was simple, but how to pause it was not described. I unplugged the AC cord, then detached the clamps.The Display:It's got a lot of lights! They blink and change colors! Some of them seem to be trying to communicate with you, but the message is a bit unclear.The metered values of voltage, amperage, and temperature are nice. Nicer would have been if they included watt hours pushed into the battery.The little "filling battery" animation is cute, but in my case it simply went up to 60% and then didn't budge for hours. During that time the voltage was sitting around 13.7V, which seemed too low. However when it finally made it to 80% things started to happen; the voltage started increasing to an eventual 14.4V and the amps slowly fell from 10 to 5. I suspect that the filling battery animation doesn't mean much for LiFePo4 charging, but that's fine because the charger seems to know what it's doing. When the voltage reached the max the charger turned itself off, and as I said the battery seems to be 99% charged.There's also a "wheel of lights" which is kind of annoying at first; I think it's meant to let you know which charging stages have been completed. It's probably useful for lead-acid charging.And finally there's the Mode Button. It stays brightly lit and cycles through colors for no discernable reason. I think along with the wheel of lights it may be trying to entertain silverfish and spiders.

It came "new", but it looked like it was banged up and used, the metal chrome on the alligator clips started to flake off and make a mess, they were also cheap and thin and hard to use as they bent sideways when trying to open them.

For the price I paid this is an awesome little charger. It will do everything to include lithium batteries. It also repairs lead acid batteries. After it repaired my lead acid deep cycle battery The battery showed 13.7 volts. Which was a bit higher than max charge was giving me before. When I used it to charge my lithium battery it seemed to function fine. Would concerned me at first was the amount of charge as it was giving less than two amps for the charge. Upon reading about it it's slowly charges at first while it checks the battery and cells, and then increases charge as it continues. The last I checked it was charging at 8.9 amps to the lithium so that's good enough. I don't plan on having to charge fast anyway so this will charge completely depleted batteries overnight.

Buen cargador recomendable
