I bought this charger for my motorhome. I have installed 4 Li Time 100 Amp Hour batteries. I have a 100amp charger already in the rig. I have a smaller 2500 generator (quiet) that could not handle high amperage. This is why I installed this charger. I liked it because it is a Lithium charger. According to my motorhome metering it charged at 30 amps with a 5amp A/C draw. I like that there is an on/off switch. Both chargers worked together fine.

Well built and has about a 30sec delay (w/switch left on) so starting the generator works great. I use 2 of these 40a chargers at the same time with a honda eu2000i generator for my off the grid home.

Only able to use one time so far on my LiTime 300 AHr battery. No problems with the single use. Came well packed and in excellent condition, which not all purchases do these days.

wow, I was shock how big it was and how heavy it is I feel t was made damn good I loved it yes i do plan to buy more stuff from this company if u want the best buy it here u will not go wrong

I sent a pic of what I had for a converter/ charger, your tech service told me that it was just a charger and I needed a charger that would fit my new LifePO4 batteries. So I went with what they suggested, but when received it would not work in my application. Still waiting on RMA/RGA from LiTime. They said it would arrive in 2-3 days over a week ago!
