Overview
The Victron Energy BPA000100010R is a Battery Alarm GX panel for monitoring a 12V or 24V battery bank and warning the crew when voltage moves outside the set limits. It gives both audible and visual alarms, so a low battery condition or charging fault is easier to catch before it becomes a larger electrical problem on board.
The alarm thresholds are set with DIP switches, which keeps setup simple and does not require a separate display or software tool. Standard 12V settings include a 10.5V low alarm, 11.5V low alarm reset, and 15.5V high alarm; standard 24V settings include a 21V low alarm, 23V low alarm reset, and 30V high alarm.
A potential-free relay contact with normally open and normally closed contacts lets the alarm signal be tied into another warning circuit or control panel when a remote indication is useful. For boats with house batteries, start batteries, or a small DC system that needs a clear local warning point, this panel gives a straightforward way to keep voltage problems visible.
Key features
- Monitors 12V or 24V battery banks for low and high voltage alarm conditions.
- Audible and visual alarms help make battery voltage issues noticeable at the panel.
- DIP switch programming sets battery voltage type, alarm thresholds, and hysteresis without software.
- Potential-free contact includes normally open and normally closed terminals for external alarm signalling.
- Standard 12V setup uses 10.5V low alarm on, 11.5V low alarm off, and 15.5V high alarm values.
- Standard 24V setup uses 21V low alarm on, 23V low alarm off, and 30V high alarm values.
Installation and setup
The Battery Alarm GX is intended for panel mounting where the alarm can be seen and heard from the helm, nav station, electrical panel, or another protected control area. During installation, the DIP switches are set for the battery system voltage and the preferred alarm behavior before the panel is put into service.
The wiring includes battery positive and negative connections, plus the relay contact terminals for external signalling. The normally open and normally closed contact options give flexibility when connecting the unit to another alarm input, indicator, or control circuit.
Electrical integration
This unit is useful on boats where battery voltage needs a simple local guard without adding a full monitoring display. It can be used alongside chargers, solar charging equipment, alternator charging, or DC distribution systems to warn when voltage drops too far during use or rises too high during charging.
The adjustable hysteresis helps prevent nuisance cycling around the alarm point. For marine electrical panels that see changing loads from pumps, electronics, refrigeration, lighting, and onboard accessories, that behavior matters because battery voltage can move quickly when equipment switches on and off.
Use cases on board
The Battery Alarm GX is a practical match for cruising boats, fishing boats, workboats, and refits where the crew wants a dedicated battery warning panel instead of relying only on occasional meter checks. It is especially useful at the helm or main electrical panel, where a clear alarm can prompt a quick look at charging status, battery isolation, or load management.
Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.
Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.
Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.
Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.
Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.
To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
