WAVLINK 280W Smart Battery Charger, Max. 20A Trickle Charger with LCD Display, for 6V/12V/24V Lead-Acid/Lithium/LiFePO4 Batteries, Battery Maintainer and Desulfurizer for Cars,Boats, Motorcycles

Works dang well

i am a vw technician so i use the scan tool a lot and ive found this works very well for keeping the vehicle voltage at about 14v with the key on. make sure all accessories are off and it should hold nicely.

Right outa box and right to work, took about 30 seconds to hookup. Ive got it on my 280ah Lifepo4 battery and its cruising right at 19.8 amps with the cooling fan running. Pretty quiet, about as loud as my gaming laptop fan running. Great value, will take a little time to top off my battery @ 20amps but its worth the price difference between 20 and 40 amp charger. Intuitive design, great charge rate for its size and portability. Easy to read display and easy push buttons and settings. So far I love it, will update if it suddenly craps out. Update: took about 12 hours to top off my new 280ah lifepo4 (~45%) running at a consistent 19.0-19.4amps @ 14.4v. Very happy with the performance 👌

Seems to work well. Would like to see some type of light to indicate when when fully charged as the screen is difficult to read unless your looking straight down at it. Needs more illumination I feel.. Wiring a little light to do any serious desulfation. That being said, it has some nice features and works well enough that I will be keeping it. Will do update (if needed) after use awhile.

Great little charger. I have been using to charge LiFoPo4 batteries and then doing a capacity check on them down to BMS cutoff. The thing I didn't realize is the force button on this doesn't work when it is in LiFePo4 mode and when the lithium battery is cutoff and waiting for a charge, the lithium mode won't charge. Simple solution is to put in lead acid mode and then use the force to get the LiFePo4 battery started. I normally leave it in force mode for about 30 seconds or long enough to then switch back to the LiFePo4 mode and then it will charge fine. If the battery isn't depleted to cutoff this wouldn't be an issue. I bought this for the features but especially for the force mode and it works if selecting the lead acid battery type. Not sure if this was by design, but there is a use case for force mode even when trying to charge LiFePo4 batteries.

This product is awesome saved my 4 commercial truck batteries. Wow best $50 I ever spent. Easy to use as well

After shopping around for a few weeks I figured a 14.6 volt Lifepo4 20 amp charger was going to cost me an average of $100, some more some less. Then I found this one and it had good reviews so I ordered it. It was on sale for $46. I received it, I was impressed with the quality of the unit, I hooked it up to my house battery with the solar still hooked up and it charged up fully taking about 2 hours. That battery is almost 3 years old and probably hasn't been fully charged like this in those 3 years. But it's running great and I will get another battery as this charger will easily handle any battery that you have according to the selections that I see on it. So far I am highly satisfied with my purchase. If anything goes wrong I'll come back and let you know. I highly recommend purchasing one for yourself and maybe even a family member or a friend.

Didn't work as advertised. Returned and got an actual lithium battery charger.
