Victron Energy Smart Battery Protect 12/24V - 100A

One of the best ways to reduce the life of a lead-acid battery is to repeatedly over-discharge it.  This can cause damaging sulphation that impairs a battery's ability to accept and maintain charge.  The Victron Smart Battery Protect 100A solves this problem 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.

The 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 the 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.

It 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. It may also be desirable to have essential loads (e.g. VHF, lighting) routed outside of the device so that these can always be used, regardless of the battery voltage.
