### ⭐⭐⭐⭐⭐ Great charger and good price.
*by D***D 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.
