Outstanding charger!
Outstanding smart charger at a great price. Comparable to several other marine chargers that cost a lot more. Charges quickly and safety for all battery types.Add on the remote monitor to track the chargers progress - well worth the price.

Great product at a great price
This is my second charger, I was very happy with the first but it took a heavy spray of salt water when a hose broke. It worked perfectly before I let it get drenched. It has options for many different battery types, easy to setup and monitor.

Great charger and good price.
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.

Good charger
Did not realize that it did not come with the power cord or cabling needed. Easy to set up and install with clear instructions otherwise. Does not come with a physical manual. Charges my batteries at the expected rate.

easily programmable for different battery types and/or charge profiles
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.

Great value for a 3 bank charger
I recently installed this on a boat after an old charger died. It was easy to install and word great. It offers plenty of charging patterns and lights provide useful status updates. A great value compared to other models for marine chargers.
