WAVLINK 450W Smart Battery Charger, Max. 35A Trickle Charger with LCD Display, for 6V/12V/24V Lead-Acid/Lithium/LiFePO4 Batteries, Battery Maintainer and Desulfurizer for Cars, Boats, Motorcycles

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.

Can’t beat it for the price,Used it to desulfate 4 6V 340ah deep cycle batteries and it worked as intended. I am sure this will be great for any other charging needs in the future.

I’ve used this on a couple, of vehicles that sit for periods in my driveway and the set up and menu scroll is very easy and straightforward. Pumps out amps to match the battery draw for charging. I do wish there was a SAE splice to allow using other cables as I permanently mount ring terminals with a SAE plug to my batteries to allow quick connecting chargers to my vehicles as I rotate chargers from vehicle to vehicle and I don’t like the bulky alligator clips as they pop off sometimes or won’t let me lower the hood completely

charger works great, I used this charger to charge several "LiFePO4 12V 10Ah" UPS battery backup batteries.If set to the LiFePO4 setting, this charger will top off the battery to 14.6V which is what is needed to reset the battery's BMS (Battery Management System).I also used this charger to recharge three Elfhub 100Ah 12.8V LiFePO4 solar batteries and 1 Ecoflow 100Ah 12.8V battery.As with the smaller batteries, this charger fully recharged the larger 100Ah batteries with no issues and was able to reset the BMS. BMS will re-balance the cells they control when they are topped off so it is important to top them off on occasion. Sometimes simply running batteries on a solar controller won't be enough to fully top them off.This charger works exactly for what I need.

The media could not be loaded. 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.

Love this little charger it works great. It even automatically senses your battery type and sets all the charging parameters so if you're a dummy you're all good to go.

It's a 7 stage smart charger and I've had a few of them in different locations where I have stuff that uses batteries 🙃This one stands out because it does the lithium too and lets me override and manually charge and select the levels I want. Also good that it has the port to attach it to vehicles where I already have a quick connect attached to the posts (motorcycle and vehicles already set up with smart trickle chargers, etc.)Once in awhile the ad mentions "trickle" but a true trickle charge is down around 2, and a smart one cycles, and this cycles for sure, but states 5 is the minimum. Still, I think I'll leave it hooked up for trickling purposes in some cases when I'm gone for one or two months, but I don't think I will when I'm going to be gone seasonally.Lots of versatility for this price point!Where's the case? (Doesn't have one but the box works fine), I don't like that the power cord can be and or has to be removed (and isn't readily interchangeable with some other power cord you happen to have nearby when you need it). In other words, keep all the pieces and parts stored together!I wish the cords were longer! For a variety of reasons, but one of the biggest is when you need to leave a charger on an SUV or a pickup and you want to put the charger itself under the vehicle so it's protected and you can lower the hood to protect from the elements and to stop the underhood lamp from burning... Longer battery connection cords are better! Yes there can be workarounds by using a set of jumper cables chain clamped... But old school mechanic types totally freak out when you do stuff like that (just don't invite them over when you're using multiple connections to reach where you want 😉)... And if you don't want them to stop by unannounced -don't leave your hood up! LOL

So far, so good. I like the fact that these are basically the same as another product. But priced reasonably. I like the fact that you have so many controllable variables. I will be using them to charge LiFePo4 batteries.Will Update Later.Update: Worked great on the LiFePo4 batteries. Worked well on the gel cell lead acid batteries. No problems thus far. Ran cool (fan forced air cooling).
