VEVORSmart Battery Charger, 35-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 tested it on a 100amp lifepo4 battery. On a 50% charged battery, with setting on 35amp, the maximum amperage was 29 amps. On a fully discharged battery (below 3%), on the Auto charge setting, I saw 32amps in, for a period of time. The instructions are poor, ok, but it is quite simple to select the battery type, then the voltage, and then the charge rate, and press start. Do not press Start until all the other settings are set, and clips are connected. The fan is not loud, but is noticeable. The charging wires warm up but not warmer than my smartphone during a fast charge. I will update later if I find something else, or If missed important feedback info.

So far so go, will update again later. After reading low ranking reviews, came to determine anyone charging lipo. Batteries had theor charger catch fire or burn out. While I cannot confirm or deny that this what I will say.There is a specific setting required to be set befor connecting a battery to any given connector. I am currently trickel charging 4 12v car batteries to save myself from having to buy new batteries for my plow trucks every winter.Setting the charger and connecting the batteries, was clear that it instantly recognized the current voltage amd over all general health of all batteries. Took several days for some of the batteries to fully charge and reach their desired state.As this is the only function I plan to use them for, am update will come this winter.

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.
