Customer Reviews for VEVOR Smart Battery Charger, 20-Amp, Lithium LiFePO4 Lead-Acid (AGM / Gel / SLA) Car Battery Charger with LCD Display, Trickle Charger Maintainer Desulfator for Boat Motorcycle Lawn Mower Deep Cycle

I've been through a few chargers looking for a quality unit and this one fits the bill! Some people complain that it doesn't push a full 35A continuously, that is true with this or any charger. All chargers work on an algorithm and will taper off. With that in mind this charger still drives a very reasonable current. I have a 300Ah RV Lithium Iron Phosphate battery that took forever to charge on my other smart charger, this one stays cool and gets it topped off in a reasonable time. I does have a built in fan that runs automatically when needed and is very quiet. It also works great on our cars. I like that it has a desulphate mode for Lead acid and I like that it has both fixed current modes or Auto current. One downside I found was that it doesn't have a low current manual mode which is why I bought the smaller version of this charger, for smaller batteries. The smaller version is probably better for most people as it is still a 20A charger. And as some others mentioned, the display could be a bit easier to read in the daylight but, it works ok. My unit was a warehouse return, it was manufactured with the wrong XT power connector on the leads which would be very frustrating for most, fortunately for me I have all sizes of XT connects in my shop and quickly replaced it. I don't know what to make of that, it turned out to be a bonus for me as I saved some money on an new/unused charger and had to change the connector although that was not an issue for me.

Works great, easy to use. The "force mode" is a game changer! No more trying to trick a battery charger into doing its job. Ive brought several batteries back to life with the "desulfate" feature as well. Highly recommended to DIYers, professionals and everyone in between!

Great charger - only complaint is that if power is interrupted, it won't automatically go back to it's charging duties. It has to be manually restarted. That's really difficult when you are 250 miles away.

Screen isn't bright enough. Hard for older eyes vand it reminds me of 1980s lcd. You have to look at screen straight on and its not bright enough

Just started testing this out on 2 lifepo4 100ah. Charges up to 20a no issue. There even a power supply mode and a professional mode for making further adjustments. One review showed their unit came with a xt90 however mine showed up with a xt60 connection. If you plan to make your own leads you may want to wait until yours shows up to see which you need.

This is a great compact multi type battery charger, if the instruction had been better translated I would have given it 5 stars.

I use it for every type of battery I own. AGM, Lead Acid, Lipo4, etc. it works fantastic. I've already been revived two batteries with the desulfation mode.

Very Satisfied with the quality of the charger. Very easy to use. Works great with a variety of batteries. Nice to be able to hook up all 4 batteries at once. Would recommend the purchase!

Used it once and the screen brightness went dim so I cannot see the selections to use the charger. Price was great and options it had were great for the price and size of the charger. Put a warranty claim in so we will se how that is handled.

This is just what I was looking for. It will charge a completely dead battery or it will start a car while the battery is dead. The automatic battery maintain is very handy just hook it up and let it work. I also use this for my garage Diesel heater and it doesn't skip a beat.
