Battery Testers

We are pleased to announce a new product, the Blue Breeze battery box vent fan. This product is design with smart logic to turn the vent fan on and off based on charging conditions, and is superior to existing vent fans that run all the time. This smart fan reduces drain on the batteries by turning the fan off during times of discharge. The vent fan is fitted with standard 2” PVC connections and an easy 2 wire hookup for 12, 24, or 48V battery banks.
