E-FAST 20A Battery Charger,12/24V Lifepo4 Lead Acid Automatic Smart Car Battery Charger, Portable Automotive Trickle Charger, Automobile Battery Maintainer for Car Truck Motorcycle Lawn Mower Boat

Great charger small and compact yet does so much. I use it for my Lifepo4 battery. The fact that it can be used on different types of batteries is great and also that it shuts off automatically when the battery is at full charge. Great price, made well and does what it made to do.

CHARGER WORKED WITHOUT ANY ISSUE AND STOPS BY ITSELF WHEN BATTERY IS FULLY CHARGED .IT WAS USED TO CHARGE A LIFEPO4 12V 100 AMP BATTERY .

Good charger. I'll be using it for a long time

A great charger and easy to handle. The digital screen could be a little better but it’s not a critical issue.

Arrived when promised packaged well. Works well on my marine deep cell battery.

This battery charger is advertised as having a 20A maximum rate of charge. I bought it to charge a 100AH LiFePO4 battery. Once plugged in, set to LiFePO and then connected the unit starts charging for several minutes at 3.1A then gradually ramps up over several more minutes to 13.1A (The display reports it is delivering 19.8A but it is actually only 13.1). Charge rate never exceeded 13.1A over several hours. So this unit was not as advertised. Then the internal cooling fan ceased operating and the unit got quite hot and the charge rate dropped back to 3.1A. I let it cool and started charging again but the fan never came on and the charge rate remained at 3.1A. The unit has failed after 1 day of use.

So far so good. Ive had it for about a week and I have recovered at least 7 batteries that I was ready to replace. So far, wow, just wow!

Works and it's cheap. Has already paid for itself by resurecting 2 Walmart car batteries.
