20-Amp Lifepo4 Lithium AGM Gel Smart Battery Charger, 12V/20A 24V/10A Trickle Charger, Maintainer for car Boat Motorcycle, Lawn Mower

I've only used this on the battery for my motorcycle so far, but it works great. It was an awesome price, I priced.It other local places near me and it was a lot cheaper, so i'm happy for. It works exactly how it's supposed to. It's super light charges, great and really easy to. I love that when you hook it up at automatically.Detects, what kind of battery it's charging So that's amazing!

I bought this charger along with a LiPuls battery. Ran the battery down to nothing and recharged overnight then ran the battery down just a little. Both times the charger sensed the amount of charge needed and switched off accordingly. Its lightweight compact and easy to setup. Easy to read panel tells you what you need to know during charging. Cords are long enough for convenient use. No complaints....This one is a winner.

This is a great charger - so much better than the old heavy style. I has all the right options to charge any type of battery.

I've now had this smart charger for one year and, so far, it's worked to charge my LiFePO4 batteries as I expected and flawlessly BUT,though it can put out 20 amps of charge when I switch it to do so the 20 amp level of charge is short lived and it will quickly default to a little over 15 amps. So, basically, it's a 15 amp charger.For those wondering if you can connect it to your vehicles 110 volt output to charge your LiFePO4 batteries, MAKE SURE THE CHARGER IS CONNECTED TO A PURE SINE WAVE inverter as any modified sine wave may damage the sensitive electronics in this unit which will use approximately 200 to 255 watts, so don't plug it into an inverter that's connected to your data port or cigarette lighter as they are typically rated at a maximum of 150 watts output or so.Yes, the fan, which stays on constantly while the unit is charging, produces noise but, when I measured the decibels from a distance of 5 feet in a room where the ambient noise level was 30 decibels, the noise level rose to 50 decibels which approximates the sound found in a quiet library. It sounds like a noticable and constant "shush" which, I suppose, is very apparent with people that get bothered by such things. I don't.I haven't tested its automatic on/off charge cycle as, when my batteries are charged I disconnect it until my batteries have been used again.I store it in a safe, dry, room temperature location. I don't drop it. I connect the smart charger to the battery BEFORE plugging it into a pure sine wave 110 volt ac source.If you do these things also this charger should last and work well.

It works just fine. I use it on a 24 volt Lithium battery setup in my boat. No complaints here.

Died after less than 2 months.I use to keep solar batty topped off but died after 2 months on low trickle charge.

Charger my lifepo4 battery from 60to full in 40 mins . Not bad

It works fine just what I needed
