WAVLINK450W 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.

Easy to use. Small but good quality product, I like the function and the ability to charge a dead battery, good price

Very noce charger works well, Downside is it will not maintain a LiPo4 wants tge LiPo4 reaches voktage tgat charger is programmed for it shuts off and must be manually turned back on, this is unfortunate, my motorhome has parasitic draw to keep many 12-v computers running that draw very small power amounts but, sitting long term if I leave the 12-v system on this charger would allow the batteries to draw down to BMS would halt the drawdown on batteries at a very low voltage. Returned need something that will allow maintaining

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.

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.

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).

gOT tHIS a mONTH aGO...........It Charge 2 300ah LifePo4 Batteries And Even Balance The Cells....Paid $59 For It...... Setting My RV Up For Solar.....This Charger Is Great.....No It Ain't Gonna Repair A Trashed Battery....But It Does Bring Back Some If They're Willin......Just Did And AGM One a Week Ago Still Shows Full Charge.

Nice, hefty, good looking charger. The multiple functions are great for many types of batteries. Don't expect over 30A, though, except for a relatively short time during the initial charging period (for SoC > 20%). Bulk charges at 24A-26A in the 35A mode. Postsales@wavlink were very friendly and helpful in exploring this issue and eventually offered me a refund.Still, paying 25%-30% more for a charger of similar quality and functionality, and rated at 20A, gets you a unit that charges 25%-30% faster!Review for charger in lifepo4,35A mode
