Description
Enerdrive 140A Voltage Sensitive Relay – 12/24V
When the engine is started, starting and auxiliary batteries are separated allowing only the starting battery to be charged. When the charge voltage reaches 13.2 volts the Voltage Sensitive Relay engages allowing both starting and auxiliary batteries to be charged. When the engine is stopped and the battery voltage falls below 12.8 volts the Voltage Sensitive Relay disengages separating the start and auxiliary batteries. The auxiliary battery continues to power any accessories without risk of draining the starting battery.

Boat Hut Insight
When considering the purchase of a Voltage Sensitive Relay, think about the accessories you plan to power. An overly ambitious setup might leave you relying on your auxiliary battery too heavily, like trying to run a karaoke machine on a boat while your friends sing off-key. Ensure the auxiliary battery has ample capacity not just for your needs, but your friends’ musical aspirations as well!
Additionally, consider the ease of installation. If your wiring skills are shaky, it might be worth paying a professional. Remember, a dodgy installation today may leave you stranded (or stuck listening to karaoke) tomorrow!
