BatteryProtect 48V-100A 

The Victron Energy BatteryProtect 48V-100A stands as a reliable guardian for your battery and connected devices, equipped with advanced protective features and precise control options. Safeguarding against potential damage to sensitive loads, this device offers over-voltage protection by disconnecting the load if the DC voltage surpasses 16V (for 24V systems) or 32V (for 48V systems). What sets it apart is its ignition-proof design, employing MOSFET switches to eliminate sparks during operation.

Programming the BatteryProtect 48V-100A is a breeze, allowing users to set engagement and disengagement voltages effortlessly. The seven-segment display provides clear indications of the chosen settings. Additionally, the delayed alarm output ensures that the alarm activates only if the battery voltage drops below the preset disconnect level for more than 12 seconds, preventing false alarms during engine starts.

For enhanced control, this device features delayed load disconnect and reconnect functions. It disconnects the load 90 seconds after the alarm, and in cases where the battery voltage increases above the preset reconnect voltage within this timeframe, the load remains connected. A special setting caters to Li-ion batteries, offering compatibility with the VE.Bus BMS for precise Li-ion battery control.

Noteworthy is the ultra-low current consumption, making the BatteryProtect 48V-100A an ideal choice, especially for Li-ion batteries. This feature ensures minimal power usage after a low voltage shutdown, contributing to energy efficiency.

With robust specifications, including IP67 protection for electronics (potted) and IP00 for connections, M8 connection, and Bluetooth non-enabled design, the BatteryProtect 48V-100A is a durable and reliable solution. Its compact dimensions, ease of installation, and a five-year warranty underline its commitment to providing a secure and efficient power management solution.

Key Features

Features of the Battery Protect 48V 100A

Over voltage protection

To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16V respectively 32V.

Ignition proof

No relays but MOSFET switches, and therefore no sparks.

Programming made easy

The BatteryProtect 48V 100A can be set to engage / disengage at several different voltages.

The seven segment display will indicate which setting has been chosen.

Delayed alarm output

The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.

Delayed load disconnect and delayed reconnect

The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected.

The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.

A special setting for Li-ion batteries

In this mode the BatteryProtect 48V 100A can be controlled by the VE.Bus BMS.

Ultra low current consumption

This is important in case of Li-ion batteries, especially after low voltage shutdown.
