​The Flex 2 - 2 Pole XD battery switch is a battery disconnect designed for vessels, allowing efficient management of the battery's connection and disconnection. This type of device has multiple Automatic Charging Relays (ACR) in one unit. For 2-3 battery systems requiring 1 or 2 ACR, a single three-relay ACR provides a drastic improvement in off-state standby current consumption and ensures onboard electrical safety, allowing the battery to be isolated during maintenance or emergency situations.
