Many caravan owners start with a factory-fitted BMPRO system and, as their travel style evolves, begin looking for more battery capacity, additional charging sources, or the ability to run high-power appliances when off-grid.
One of the most common mistakes we see is owners adding products from multiple brands and creating a mix of monitoring systems, apps and communication protocols. While this can work, it often leads to a fragmented user experience and reduced visibility of what is happening across the entire power system. Today, with the expanded BMPRO product range, there is a better option. You can now upgrade and expand your existing BMPRO system using BMPRO products designed to work together as part of a fully integrated ecosystem.
Starting with DC-DC chargers and the ProBoost40 – this is the simplest and most effective starting point most caravan owners looking to upgrade to lithium batteries. The ProBoost40 combines two critical charging functions into a single product a massive 40A from either DC-DC charging from the vehicle alternator or 40A MPPT solar charging from rooftop solar panels. This means you can charge your battery bank while driving, while parked in the sun, or from both energy sources depending on your installation.
MPPT (Maximum Power Point Tracking) technology continuously optimises solar panel performance, helping maximise the available solar energy and convert it efficiently into usable battery charging power and on the DC-DC side it works with all alternators even newer versions.
The ProBoost40 has become a popular upgrade because installation is typically less invasive than many other power system modifications. In many cases, owners can significantly improve charging performance without removing cabinetry, rewiring multiple circuits, or undertaking major electrical modifications.
It makes adding Lithium batteries easy – Lithium batteries have changed what caravan owners expect from their power systems and changed their expectations as to being able to be a little more adventurous away from caravan parks. Compared to traditional lead-acid batteries, lithium batteries can accept substantially higher charging currents, allowing them to recharge much faster. They contain more usable energy, are half the weight and have a massive lifetime compared to their poor cousin, Lead Acid versions. This is why the ProBoost40 is often the preferred choice. Its 40A charging capability helps reduce charging times while supporting the increased energy demands of modern caravans.
Whether you’re powering fridges, lighting, entertainment systems or large off-grid setups, faster charging means more usable energy faster and less downtime.
BUT… there may be a missing link – a shunt! As power systems become larger and more sophisticated, accurate power monitoring becomes increasingly important. The BMPRO PXShunt is designed to provide this visibility.
With a continuous current rating of 500A, the PXShunt measures the power flowing into and out of the battery bank. This information allows the BMPRO system to accurately monitor battery usage, charging performance and overall energy consumption. By providing real-time current measurement data, the PX-Shunt helps ensure the entire power management system has the information it needs to manage energy effectively.
Most importantly, the shunt allows the various BMPRO components to work together as part of a coordinated system rather than as a collection of independent devices. It effectively keeps your system working together. The real advantage of upgrading within the BMPRO ecosystem is integration. When your charger, battery monitoring, inverter and power management components are designed to work together, you gain a simpler installation, a more consistent user experience and better visibility of your overall power system. It also enables full integration of other devices such as Bluetooth monitoring and BMPRO’s safety systems.
Rather than layering multiple brands and multiple monitoring platforms on top of your existing setup, you can build on the BMPRO system already installed in your caravan. The result is a smarter, more capable power system that is ready for larger lithium battery banks, increased solar capacity and the growing energy demands of modern caravan travel.
How much power does your caravan really need? The 12V Guru explains how the appliances you use and the time you spend off-grid determine the right power solution for the way you travel.
Tested across three independent Australian facilities, ProBoost has been selected by Ford for the Ranger Super Duty and Mazda for the BT-50, reflecting its proven DC-DC and MPPT capabilities.
For more than four years, BMPRO has proudly supported the Idlers 4WD Club through regular education sessions focused on 12V power systems, battery management, and the rapidly changing world of lithium technology.
