Purchased another one from a diff supplier but it had issues and wasn't working as it should, found this one from SUPLIFE with great operational data and after installing, it's 100% functioning properly to charge my Lithium Batteries!!

I installed this board in June and everything seemed to work other than being very noisy.They claimed it was very quiet but it was not. We took a trip in July and after four days the batteries went dead even though we were hooked up to electric. I charged the batteries using a 10amp lithium charger and the batteries came back to about full charge.I finally had a chance to check the inverter and found that it was not charging the batteries. I then replaced it with the original inverter and it worked but I needed an inverter to charge my lithium batteries so I am asking for a replacementI still have not received a replacementStill waiting for a replacement or my money refund

This was a perfect fit for upgrading from our lead batteries to lithium! Easy to install because of the exact fit!

I upgraded the house batteries in my RV to 410Ah of Lifepo4 batteries. The original "auto detect" converter wouldn't recognize or charge at the higher rate that the lithium batteries need, so I replaced it with this unit. The ad says it has a silent fan and that couldn't be further from the truth. The fan sounds like a jet about to take off. I am thinking about replacing the fan with a quieter one or with two actual quiet fans, one on each side of the converter to help with air flow and cooling and eliminating the loud fan that comes attached to this unit. Again, this unit does a great job of charging the batteries. My biggest and only complaint about it is the noise level of the fan. If you have any "light sleepers" in the RV while using this unit their sleep is most likely to be negatively effected by this unit.

The cooling fans runs much more than the orginal unit. It is rated as 53amps, I normally get 25 amps.

Changed this converter out to handle lifepo4 batteries I installed on travel trailer - surprised how much faster they charge my lithium battery.

I had high hopes for this inverter. It was working fine. Then, as of yesterday it just stopped working. My camper was dead. I had to plug it in and now luckily I have solar because it won't work. Thank goodness for Amazon coming through with a refund...
