    Works fine
  

*by S***M on Reviewed in the United States on December 8, 2023*

Charged my 200 amp lithium just fine. The cables to the battery are smaller than I’d expect but still worked well and never really got hot.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great charger - full charge cycle of 100AH lithium Powr Queen batteries in less thah three hours
  

*by B***Y on Reviewed in the United States on March 11, 2023*

I used this to insure I had full charge on my Power Queen 100AH 12.8 vdc lithium batteries prior to installing them in my Travel Trailer.  The batteries as delivered, showed 13.15 vdc, after 2.5 hr charge cycle they read approx 13.75 vdc. The charge cycle took about 2.5 hrs.What I did not like was the supporting ops manual. It just says hook em up and go, wait for the green full charge lamp..There are three values on the screen during charge cycle, Voltage output (max I saw was 14.3), AMP output (held steady from 40.2 to 40.6). Last what I think is Charge state of  the battery(CAP), went up steadily from start at around1.4 to 70.1 late in the cycle. I  never did see what final CAP reading was, as the batt full green LED came on.The two page brochure has no explanation of the values you'll observe and what the normal range is ...
