Review on Erayco Circuit Trolling 12V 48VDC Waterproof by Jamie Behm

This is the only device that adds a much-needed protective barrier between my battery and my inverter/charger. If I'm having temperature issues, it protects the rest of my system/cable if something goes wrong. This little device is the little thing that can save me a headache and lose money. It's so easy to install and it gives me peace of mind. This is a small investment to protect a very large investment. It's great value for the price and what it does. 5 stars all day.
