BatteryProtect 12/24V 100A Victron Energy — ochrana batérie pre 12/24V systémy, 100A

BatteryProtect 12/24V 100A from Victron Energy is a battery protection device designed for 12V and 24V DC electrical systems. It monitors battery voltage and disconnects non-essential loads when voltage drops below user-selectable thresholds, preventing deep discharge and protecting battery life. The unit handles continuous currents up to 100A and is suitable for installations in marine, caravan/RV and off-grid power systems where maintaining battery health and reliable automatic disconnection are important.

Advantages

The device offers automatic disconnection of non-critical loads to prevent battery depletion, configurable voltage thresholds for different battery chemistries and operating conditions, and robust current handling up to 100A for continuous operation. Its compact design simplifies installation in confined spaces and the reliable electronic control avoids the wear and maintenance associated with mechanical relays. The unit also restores connection automatically when battery voltage recovers, ensuring seamless operation without manual intervention.

Suitable for

• Marine electrical systems for protecting starter and service batteries
• Caravan and RV power systems to prevent battery drain from appliances and electronics
• Off-grid and solar installations where automatic load shedding preserves battery capacity
• Small commercial or industrial DC setups requiring 12V/24V battery protection up to 100A

Key specifications

• Nominal system voltages supported: 12V and 24V DC
• Maximum continuous current: 100A
• Automatic low-voltage disconnect and reconnect based on configurable thresholds
• Electronic switching for reduced mechanical wear
• Compact housing suitable for confined installation spaces

How to use

Install the BatteryProtect in line between the battery and the loads you wish to protect, following manufacturer wiring guidelines and ensuring correct system voltage selection. Configure the low-voltage disconnect and reconnect thresholds according to your battery type and application to avoid unnecessary cutouts while protecting battery health. Ensure proper fusing close to the battery and use cabling sized for 100A continuous current. After installation, verify operation by simulating discharge conditions and confirming that non-essential loads are disconnected at the configured threshold and reconnected once voltage recovers.

Recommendations

Use the unit with appropriate battery types and set thresholds for the specific chemistry in use (lead-acid, AGM, gel, or lithium where supported). Combine the device with proper fuses or circuit breakers and correctly sized cables to ensure safe operation at currents up to 100A. Periodically inspect connections and mounting to maintain reliable protection in marine, RV, or off-grid environments.
