Detailed description

Designed to extend the lifespan of your batteries, the Battery Protect 12/24V 220A from VICTRON ENERGY disconnects non-essential loads before complete discharge or a level too low for engine start. This device automatically manages 12V or 24V system voltages and supports a maximum continuous charging current of 220A, with a peak current of 600A for 30 seconds. It differs from lower models such as the BP-65 (65A) and BP-100 (100A) by its ability to handle higher loads. A key distinction from the Smart BatteryProtect is its programming method via the PROG pin to GND, rather than a Bluetooth interface.

Advanced features and protection

The Battery Protect 12/24V 220A features a 7-segment LED display for simplified configuration of engagement and disengagement thresholds. It offers a specific mode for Li-ion batteries, allowing direct control via an external BMS such as the VE.Bus BMS or the Lynx Smart BMS, and can also function as a charging switch. Its current consumption is ultra-low, at 1.5 mA in operation and 0.6 mA in standby or low-voltage cut-off mode, a benefit for autonomous systems.

Safety and system integration

Overvoltage protection is integrated, disconnecting the load if DC voltage exceeds 16V (for a 12V system) or 32V (for a 24V system). The device uses MOSFET switches, ensuring spark-free operation and resistance to ignition. A timed alarm output activates after 12 seconds of low voltage, without nuisance triggering during engine start, and supports up to 50 mA. Load disconnection is also timed at 90 seconds (immediate if controlled by VE.Bus BMS), with reconnection after 30 seconds when voltage recovers. The Battery Protect 12/24V 220A is rated IP67 for its electronics (potted) and IP00 for its connections, and is mounted with a torque of 9 Nm, weighing 0.8 kg with dimensions of 62 x 123 x 120 mm. It is important to note that this is a unidirectional device, designed for current flow from the input (battery) to the output (load) only, and is not suitable for reverse currents from charging sources.

« Technical analysis of the Battery Protect 12/24V 220A »

The Victron Energy Battery Protect 12/24V 220A is a critical component for managing and protecting battery banks, particularly in marine installations where reliability is paramount. Its primary function of disconnecting non-priority loads before deep discharge is crucial for battery longevity—a significant investment on any boat. For lithium-ion systems, the ability to control it directly via an external BMS (such as Victron’s Lynx Smart or VE.Bus BMS models) is a significant technical advantage, ensuring optimal protection compliant with battery technology requirements.

During installation, it is imperative to respect the unidirectional nature of the Battery Protect: current must always flow from the input (IN) to the output (OUT). This means it must not be used to manage simultaneous charging and discharging, nor to handle reverse currents from charging sources. Special attention must be paid to the wiring of inverters or charger/inverters; these must not be connected directly to the Battery Protect’s DC input to avoid damaging the device in case of reverse current flow. It is recommended to use the inverter’s remote control port, managed by the Battery Protect, for this application.

With its 220A capacity, this model is the most robust in the standard Battery Protect range (BP-65, BP-100), suited for applications requiring management of higher loads. Unlike the Smart BatteryProtect, its programming is done via dedicated pins, which, while less interactive than a Bluetooth interface, ensures stable and reliable configuration once set. Its IP67-rated electronics enclosure provides high resistance to marine environments, making it a sound choice for installations exposed to harsh conditions.
