AIMS Power

<h3>About AIMS Power</h3><p>Founded in 2001 in a Reno, Nevada garage, AIMS Power has grown from a one-person passion project into one of the most recognized names in off-grid and backup power technology. <strong>Bruce de Jong</strong>, the company&apos;s founder and president, devoted countless hours to developing unique inverter designs that addressed real gaps in the renewable energy market — and that customer-first philosophy remains at the heart of everything AIMS Power does today.</p><h3>A Complete Off-Grid Power Ecosystem</h3><p>What sets AIMS Power apart from many competitors is the breadth of its product ecosystem. While the brand built its reputation on its extensive line of <a href="/16836-aims-power-power-inverter-14297">power inverters</a> — covering everything from compact 75-watt modified sine units to massive 12,000-watt pure sine models — it has since expanded into solar panels, deep-cycle AGM and LiFePO4 lithium batteries, MPPT solar charge controllers, portable solar generators, cables, and complete custom solar kits. This means customers can source an entire off-grid or backup power system from a single, trusted manufacturer.</p><p>The inverter lineup itself is remarkably diverse. AIMS Power offers both pure sine wave and modified sine wave inverters across 12V, 24V, and 48V DC inputs, with inverter-charger combos that include built-in transfer switches for seamless switching between battery and grid power. Several models carry ETL certification conforming to UL 458 and UL 1741 standards, making them suitable for RV manufacturers, work truck fleets, bus operators, and commercial OEM upfitters who require listed products.</p><h3>Built for Real-World Applications</h3><p>AIMS Power serves an unusually wide range of use cases. RV owners and overlanders rely on AIMS inverters and solar kits to stay powered far from the grid. Marine enthusiasts use their battery isolators and inverter-chargers to keep vessels running reliably. Emergency preparedness professionals count on AIMS systems for clean, dependable backup power when utility grids fail. The brand has also made significant inroads with industrial and commercial customers, supplying inverters to some of the most innovative organizations across the U.S. and internationally.</p><p>The company&apos;s lithium LiFePO4 battery line deserves special mention. Using only A-grade cells, AIMS Power batteries are engineered for up to 4,000 charge-discharge cycles — roughly twice what B-grade alternatives deliver. Combined with a sophisticated internal battery management system, these batteries maintain consistent output voltage right up until they&apos;re discharged, making them especially well-suited to sensitive electronics and critical backup applications.</p><h3>US-Based Support and Continuous Innovation</h3><p>One of AIMS Power&apos;s most appreciated differentiators is its commitment to U.S.-based technical support. The company operates a dedicated engineering and tech support facility in Reno and offers lifetime free technical assistance to customers, available by phone or email. This accessibility — combined with a willingness to work directly with customers and factories to solve design challenges — allows AIMS Power to iterate on its products faster than many larger competitors. For those who need tailored solutions, the brand also offers custom solar kits and works with OEMs and upfitters on application-specific builds.</p>

Product Details

The AIMS Power BATISO300 is a heavy-duty 300-amp battery isolator designed to manage power distribution between multiple battery banks. It allows alternators or charging sources to charge two or more battery banks simultaneously while preventing discharge from one bank to another, protecting your primary starting battery from being drained by auxiliary loads.

This isolator is ideal for RV, marine, off-road, and commercial vehicle applications where a dedicated auxiliary battery bank is needed for powering accessories, inverters, or house loads without compromising the vehicle's starting battery.

Key Features:

  • 300-amp continuous rating for high-demand applications
  • Prevents reverse current flow between battery banks
  • Allows simultaneous charging of multiple battery banks from a single alternator or charger
  • Protects the starting battery from being depleted by auxiliary loads
  • Heavy-duty construction suitable for RV, marine, and off-road use
  • Compact and durable design for reliable long-term performance

The AIMS Power BATISO300 provides a simple, reliable solution for dual or multi-battery setups, ensuring each bank is properly charged and isolated. Compatible with 12V and 24V DC systems commonly found in RVs, boats, trucks, and off-grid installations.
