Review: protecting battery bank - I have 4 deep cycle batteries I've been using for powering 12V wenches as well as an inverter. I wanted to be able to isolate the batteries from each other in case 1 battery went bad and shorted, as well as protect batteries from an external short. Currently using a 100 amp battery charger but eventually I will be installing several solar panels for charging. This so far seems perfect for the job. I connected each battery to it's own breaker then connected output of each breaker together. I connect to the output of the breakers for power as well as for charging batteries. This also works as an on/off switch as well, with a push of the breaker button the breaker disconnects the battery, push the side lever and breaker is reset to on. The only thing I wish was different is the tab next to the breaker's posts, it limits the angle you can connect the wire to the post. Without the tab there I could use a straight copper buss bar to connect all of the outputs instead of needing something that loops around it.

### ⭐⭐⭐⭐ Four Stars
*by J***O on November 29, 2016*

works for my solar system

### ⭐⭐⭐⭐⭐ Use it for trolling motor setup
*by R***E on May 10, 2014*

Great protection for a trolling motor. Like that it has a reset which doubles as a quick disconnect at the batteries. Not sure of its longevity in marine service but batteries are in an enclosure. No issues through one full season.
