Details
“Power! Unlimited power!”
At the heart of our power systems for Mercedes-Sprinter-to-Adventure-Van conversions and timeless Airstream Restorations, you’ll find the Dyness B4850 — a 48-volt, server-rack style battery for off-grid homes. Why would we choose a battery designed for residential off-grid applications, when everyone else uses batteries designed for vehicles? We thought outside the box. And, rather than use a battery profile originally designed for engine compartments, we specified this LiFePo4 battery for its impressive capacity of 2.4 KWH, and it’s slim form factor. A Sprinter Van might look large on the outside… but, once up-fitted for Overland-style trips far from civilization, space becomes scarce.

We found that using a server-rack style battery for off-grid Homes allows much higher power density for the available space. Our power systems can boast 9.6KWH (four Dyness 4850 batteries), in half the space of a comparable 12 or 24v conventional Lithium battery setup. Most importantly, our clientele are, ahem, power users… and can’t afford interrupted energy during extended periods of inclement weather or low solar input.
They’re creators, investment strategist, and remote workers that relay on consistent energy for their computers and internet providers like Star Link. There are more reasons why we chose the Dyness B4850 for our off-grid builds. Reliability, achieved with cell-level monitoring controlled by an internal Battery Management System and balancing through CAN-BUS communication gives us the peace-of-mind knowing our Adventure vans will be reliable and safe for years to come.
If you’re looking for a battery for off-grid residential applications like a cottage, beach house, or cabin, we’ve come to rely on the Dyness B4850 LiFePO4 for our Adventure Van builds. If they excel in this harsh environment, you can be sure the Dyness B4850 will fit your off-grid needs.
