### ⭐⭐⭐⭐⭐ 







  
  
    Great charger and good price.
  

*by D***D on Reviewed in the United States on May 28, 2020*

I've been using Sterling chargers for about 10 years and have never been disappointed. They are multiple stage units with built in power saving mode to extend the life of your batteries. The 24V 20AMP unit has small screw on terminals and the 24V 30AMP unit has the larger bolt lugs. The unit has multiple preprogrammed charging profiles for different battery types, and one custom charging profile if you want to set up your own bulk, absorption, and float voltages. It can be used as both a charger or a standalone power supply. It is light, quiet, and easy to install. I highly recommend this product.

### ⭐⭐⭐⭐⭐ 







  
  
    easily programmable for different battery types and/or charge profiles
  

*by K***R on Reviewed in the United States on October 24, 2020*

I installed this charger on a 31' cruising power boat, with conventional flooded lead/acid batteries, split into two banks: start & house. It works very well, can handle house 12V loads while plugged in and keeping the house bank up.  ...  Easy to install, seems like a tough unit, the front face has a lot of lights and indicators but is actually pretty simple to read once you study it a little.

### ⭐⭐⭐⭐ 







  
  
    Overall good product with nice display
  

*by T***C on Reviewed in the United States on November 13, 2013*

I like the ability to see how the batteries are charging from the helm without going into the bilge. It was easy to install, although directions would have been nice. Removing the ends to get to the screw holes was interesting. No screws are included for installation.Lastly, it would be nice to view the batteries charge state when you are not connected to shore power. This unit only gives you a read out when connected to shore power. I would have thought it would give you a DC voltage readout when not hooked to the dock.I still give it 4 stars because it does work well, it just needs to have that 1 feature improved for viewing without AC power.
