The Power to Take You Further
Traveling by RV can involve a significant amount of time off-grid. When exploring the rugged beauty of the outdoors, the last thing you want to worry about is the smooth operation of your RV power needs.
Unlike traditional lead-acid batteries, lithium batteries for RV use are significantly lighter, and provide a faster charge and longer battery life. Lithium batteries are the optimum choice for solar charging. So that road trip you’ve wanted to take across seasons and state lines? It’s the start of a beautiful adventure.
We use only the highest-grade lithium iron phosphate encased in steel and meeting the UL1642 standard (UL file no. MH64383). This material and engineering make for unparalleled reliability, stability, and safety.
We took the standard battery case up a notch with built-in rubber feet, radiused corners, 96.7% larger terminal connection pads, interior molded ribs for structural security, and the highest-grade ABS plastics with additives for fire retardancy. Our innovative case design changes the scope of the industry.
To keep our batteries as powerful and efficient as possible, we’ve welded our cells via thick copper/tin machined collector plates, welded all interior pack points, added a press broke flange at each end to create a mechanical backbone for the BMS, used high-grade wiring and ring terminals throughout, and treated connections with industrial epoxy for long-lasting protection.
Battery Management System (BMS)
Our “smart” BMS design has abundant features to provide you with the safety and performance you desire, such as: low-temp discharge, auto-shutoff, short circuit protection, low and high-voltage shutoffs, and overcurrent disconnect. Our structurally sound BMS board features a bolted design, eliminating all unnecessary solder, resulting in one cohesive pack for years of trouble-free performance.
