Background for those just needing small setup and charger! New to all this but after watching videos for months doing the formulas !I just wanted to get two 12 volt 100 AmpliFeP04 batteries! A 2000 watt inverter and charger!The Vevor was very easy to use ! Hooked up set to LiFeP04, set to auto on volts and auto on amps hit start 4-6 hours later complete charge on first battery!Repeat on second battery, same worked great and auto shut down after charge! Don’t no if I got lucky and got a good one ! But I liked it so well orderdthe updated 35 amp model! Build quality it is pretty hefty for this price range fan comes on under beginning charge gets warm not hot! Read out is great !Shuts down and shows complete charge ! Will update as I check this out! Just wanted to be able to power fridge in case of power out!

I have used this to charge 4 new out of box LiFePo4 batteries. I could see the current and voltage the charge cycle was putting to the battery and it worked flawless. The charger has some weight to it, the power cord and battery leads good length not too short like many others. The battery clips are perfect size and there is a wire between the two jaws {many only run the wire to one side of the clamp}. the display is large and easy to read and buttons to select settings easy to understand. this will be kept in my RV for LiFePo service along with being able to do Lead Acid in a vehicle when necessary. With out a doubt it is the best solution in the 20amp Lithium battery chargers available and worth the extra few dollars.

This charger works great, and it really is a smart one. The only thing I don't like is the screen is hard to see outdoors, but then again so are cell phones. So I won't deduct any stars over that. Well built and rugged case also.

I compared several battery chargers and chose this one. It was the right choice.

The charger arrived on time and works fine. I didn’t notice it getting hot. I charged a LiFePO4 battery and didn’t have any problems. It looks like pretty good quality product.

Strongly recommended, this charger works perfectly on my 4S - LifePo4 and 12V Lead Acid. Check below for my testing results.Ignore other reviews stating this charger is problematic for lifepo4 batteries, these user have no clue how a Lifepo4 charges, their review shows a voltmeter comparing the charger voltage when the charger is outputting 20A ! It's normal to have a voltage difference between the charger and the battery terminals at 20Amps due to resistance in the leads. If his battery clips at 13.3V, is probably an issue with his cells or his BMS is clipping, nothing to do with the Vevor charger.PROS OF THIS VEVOR CHARGER* Intertek Certified : The Vevor charge has a proper valid certification (Intertek), this is a requirement for Canada. Intertek is a good testing lab (for CSA / UL). Never buy a charger with only CE certification.* Perfect for LifePo4. The Vevor charged my Lifepo4 up to exactly 14.65V (4S) at bulk charging measure with my Fluke. My battery reached 14.65V for a **very short** period, then the charger worked perfectly and stopped the current. The LifePo4 battery then slowly drops back to float. At 13.5V float, your LifePo4 (4S) is full.* Lead Acid charges perfectly. Tested my 12V deep cycle batteries, works like a champ. After the bluk charge, it trickles it at 4mA. Perfect.* Double wire gator grips, YES ! The gator grips have an internal jumper wire to make sure BOTH sides of the jaws have lead power, such a brillant idea. Lead wires are not oversized, but are a decent gauge.* Auto mode works perfect, settings are simple and intuitive.* 20 Amps charging is just impressive with such a small form factors.* Good value for the price.

I have a lot of chargers already. Bought this one for a new lithium battery I purchased. It is very smart and worked well with the new battery. I like it a lot, it will be my goto charger for all my batteries now. Highly recommended.

Reasonable charger for a price. It do what it suppose to do. With Lifepo4 280AH battery on Auto it briefly starts with 20A and quickly drops to 15A. Device is heavy and seems well built.However note,1. Cables overheats at 15-20A - it required to be replaced right away - save yourself and charger.2. Charger doesn't start automatically on LifePo4 batteryI got this charger to charge my sump pump battery - needs to be connected all the time and take care of battery in a smart way. I doubt it is up to job in my case until manually controlled as stated above.Update: At 15A charger body becomes to be very hot on touch, fan is working, but it looks it is not sufficient.Update: Charger is properly charging LifePo4 battery, with 2 cycles, by voltage and by current.Conclusion: Recommend it if you want to charge battery fast and properly, probably not the best as maintenance charger.

Good charger for the money

Does not perform as advertised! Only charges lifepo4 batteries to 30-40% capacity after three days! Tried on multiple batteries. Falsely advertised!!!! Only puts out 13.55 volts at max output but device screen shows 14.2, see pictures. Lifepo4 batteries require 14.4 volts to fully charge. Don’t waste your money!!!!

This works as advertised but it is a little concerning how hot the wires going to the battery get while charging at higher amperage. The wires do not get hot while charging on the 10 amp setting or under, but it takes too long to charge a 100ah lifepo4 at 10a for me. It most definitely needs a heavier gauge lead for me to be comfortable leaving it unattended while charging at 20a. Every time the wires heat up and get soft. Everything else is great though, super easy to use. Just really wish the hot wires were not a concern.
