Victron Energy BatteryProtect Programmable Battery Protector, 7-Segment LED Display

Overview

The Victron Energy BatteryProtect is a programmable battery protector that disconnects non-essential DC loads before the battery is drawn down too far or before there is not enough reserve left for engine starting. This range covers 12/24V models at 65A, 100A, and 220A, plus a 48V 100A version, all with a 7-segment LED display for setting the disconnect and reconnect behavior.

On a boat, it is a useful safeguard for house loads such as electronics circuits, lighting groups, refrigeration controls, pumps, and other DC equipment that should not keep draining the battery after voltage drops below the chosen threshold. The 12/24V models operate over a 6-35V range and auto-detect system voltage at initial power-up, while the 48V model is built for higher-voltage DC systems.

The unit uses MOSFET switching rather than relays, so there are no relay contacts or switching sparks. Its electronics are potted to IP67, while the power connections are IP00, so it belongs in a protected electrical area with proper cable support, fusing, and separation from spray or loose gear.

Key features

• Disconnects non-essential DC loads before deep discharge can damage the battery or leave too little reserve for starting.

• Programmable engage and disengage voltage settings shown on the built-in 7-segment LED display.

• Available for 12/24V systems in 65A, 100A, and 220A current ratings, plus a 48V 100A version for higher-voltage banks.

• 12-second alarm output delay, 90-second load disconnect delay, and 30-second reconnect delay help prevent nuisance shutdowns from brief voltage dips.

• Short circuit proof alarm output supports up to 50mA for a buzzer, LED, or relay.

• Special Li-ion mode allows control by a VE.Bus BMS or compatible external BMS load disconnect signal.

• Over-voltage protection disconnects loads above 16V on 12V systems, 32V on 24V systems, and 64V on the 48V model.

• MOSFET switching gives ignition-proof operation with no relay sparks.

• Potted IP67 electronics help protect the control electronics, while IP00 connections require installation in a protected electrical compartment.

Variants

The BatteryProtect range is offered in several electrical configurations. The main differences are system voltage and maximum continuous load current, so the correct model depends on the battery bank voltage and the current draw of the DC load circuit being protected.

The 12/24V versions share auto voltage detection and the same 6-35V operating voltage range. The 48V version has its own voltage range and thresholds for 48V battery systems.

• BPR000220400: 12/24V system voltage with 220A current rating. This version is for higher-current protected load circuits where the cable size, fuse, and bus layout are matched to a 220A BatteryProtect.

• BPR000065400: 12/24V system voltage with 65A current rating. This lower-current version suits smaller DC load groups and branch circuits that do not require the larger terminal and current capacity of the 100A or 220A models.

• BPR000100400: 12/24V system voltage with 100A current rating. This mid-range 12/24V version fits many house-load protection layouts where 65A is not enough but the 220A unit is unnecessary.

• BPR048100400: 48V system voltage with 100A current rating. This version is for 48V DC installations and uses the 48V shutdown and restart threshold set rather than the 12/24V threshold set.

Electrical and system integration

BatteryProtect is a unidirectional device. Current must flow from the IN battery terminal to the OUT load terminal, and reverse current from the load side back into the unit can damage it. When the product is used to interrupt a charge source, the installation still needs to follow the correct IN to OUT current direction.

It should not be installed in the main DC feed to an inverter or inverter/charger. For those loads, the safer setup is to let the BatteryProtect control the inverter's remote on/off input rather than switching the high-current inverter DC cable directly.

Installation and setup

Install the BatteryProtect in a well-ventilated area, preferably close to the battery but not directly above it where corrosive gases may be present. Use cable size and cable length that match the protected load, and fit a properly sized fuse in the positive cable between the battery and the BatteryProtect.

The load output should be left disconnected until programming is complete. A remote on/off switch can be connected at the remote terminal, and the alarm output can be wired to a buzzer, LED, or relay that matches the system voltage.

Use cases on board

This range is a good match for cruisers, fishing boats, workboats, and sailboats that need a controlled low-voltage disconnect for house loads without putting the whole DC system at risk. It is especially useful where radios, navigation electronics, lighting, pumps, or other non-essential loads should shut down before the battery bank reaches a damaging level.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
