(Group 24)
 
Expion360 engineered this advanced lithium battery with extremely stable LiFePo4 chemistry optimizing power and long-term performance.  The VPR 4EVER battery strikes the perfect balance between price and performance.
 
The very common Group 24 size is available in 95Ah allowing for a simple replacement of your current RV Marine AGM or lead-acid battery. This battery is able to charge faster utilizing Zamp Solar's lithium charging profile in every 10, 15, and 30 amp charge controller.
 
What Makes Expion360 the Best Choice in Lithium Batteries?
 
Designed and Engineered in America — Expion designs and oversee all aspects of their lithium batteries with special attention to the smallest of details. Expion360 is the right choice where quality meets the price.
 
Lithium Cells — We source only the highest-grade lithium cells in the world for unparalleled reliability. All lithium cells used in production are fully listed and meet UL1642 standard (UL File #MH64383).
 
Box Design — From concept to finished product, the usage of color and texture is a hallmark of their innovative box design that completely changes the scope of the industry. The X, Y & Z axis within the interior space is structurally secured with molded ribs rather than foam filler that is found in most of our competitors. We only use the highest-grade ABS plastics and infuse 10% glass fill into our mil-spec battery case that meets UL-94 VO for fire retardant rating. First in the industry to have rubber feet built-in on every battery box, this feature aids in the elimination of vibration and sliding issues. Radiused corners heighten the appearance and strengthen the edges for a sleek and sophisticated profile.
 
Polarity Pads — Their oversized polarity pads are 96.7% larger than a standard terminal. This forward-thinking design increases the strength and structural integrity by allowing better heat dissipation and a 19% increase in current-carrying capacity. Opposing polarity pads aid in mounting flexibility and reduced cross polarity dangers.
 
Cell Pack — Expion has eliminated nearly all solder points within their interior pack design. Because mechanical connections are the most efficient way to transfer power and reduce resistance and heat buildup, all cells are securely welded via thick copper/tin machined collector plates. The collector plates in our design are thicker than the industry norm and press broke at each end to create a mechanical backbone to connect to the BMS substrate. High-grade wire, ring terminals, and heat shrink are generously used throughout the interior. All terminal connections are treated with industrial epoxy for long-lasting corrosion protection and locked-in durability.
 
BMS (Battery Management System) — “Smart” is at the heart of their BMS design with an abundance of features. For the cold-weather enthusiast, we have built-in a low-temp discharge and charge auto-shutoff. Low and high voltage cutouts, short circuit protection, and overcurrent disconnect are also managed by their intelligent BMS. While others may overlook the safety importance of structurally securing the BMS board, our process incorporates a bolted design that creates one cohesive pack. The addition of terminal connections and an oversized heatsink increase the reliability of our BMS to give years of trouble-free performance.
