The Victron Smart Battery Protect 220A solves this issue by automatically disconnecting your battery from non-essential loads before it reaches a damagingly low state of discharge. When the battery voltage drops to a certain level (lower threshold) the loads will be disconnected and when it rises again to a certain level (upper threshold) they will be reconnected. These thresholds are user-configurable to suit your application.\u003c\/p\u003e\n\n\u003cp\u003eThe Smart Battery Protect has a host of other features (see below) and is easily configurable using the built-in Bluetooth in conjunction with the VictronConnect app (see Downloads\/Links tab).  The voltage thresholds can aso be programmed manually using a dedicated pin on the terminal block and the Bluetooth function can be disabled if preferred.\u003c\/p\u003e\n\n\u003cp\u003eIt should be noted that the Smart Battery Protect is not designed to accommodate reverse currents from charging sources, so these should not be connected through the device.
