Not much room for a dual battery system in your vehicle? This power hub is designed to be fit in the gaps, behind a seat or adjacent to slide out storage assemblies. And this power hub features an in-built 40A DC-DC charger with solar input, which makes it easy to disconnect or connect the dual battery system. The ATEM POWER slimline lithium battery features prismatic cells which are more stable and shock-resistant than cylindrical cells. And the power hub with 40A DCDC comes in a robust steel case with powder coated finish for added durability. This slimline lithium battery with in-built 40A DC-DC charger is less than half the weight of a lead acid battery yet doubles the usable power for huge weight saving. And the power hub can deliver up to 2,000 rounds, several times that of a lead-acid battery so you don’t need to constantly replace your power hub. The Anderson plugs & cigarette socket allow this power hub to be neatly connected and easily removed for different applications.
  • In-Built DC-DC Charger: This slimline lithium battery features an in-built DC-DC charger for superior convenience.
  • Solar Input: This power hub with 40A DCDC can directly and effectively pull power from solar panel with the Anderson plug for solar input.
  • Slimline Design: This power hub can fit in the tightest spaces thanks to its slimline shape and is less than half the weight of an equivalent lead-acid battery.
  • Prismatic Cells: Prismatic cells of this slimline lithium battery provide better performance than cylindrical cells as they are more stable and shock-resistant.
  • Longer Life: This ATEM POWER power hub is a win in lifespan as you can get 2,000 cycles, several times the life expectancy of standard lead-acid batteries.
  • High Quality BMS: It provides 100A max. continuous discharge current & 200A (≤7S) max. pulse discharge current and monitors and optimizes each cell.
  • Output / Input Studs: This power hub with 40A DCDC comes with inverter suitable output / input studs.
  • Premium Battery Monitor: The battery monitor allows you to easily check the battery’s real-time status.
  • Universal Fitment: Our RV battery monitor is compatible with all common battery types, including lithium, lead-acid (AGM, gel, wet), and nickel-metal hydride.
  • Super Versatile: With this RV battery monitor, you'll always know the state of your deep-cycle battery, whether it's in a 4WD, RV, or boat solar system.
