One 24V battery beats two 12V! When putting batteries in series small mismatches between them can balloon over time and cause all sorts of performance issues after years of seemingly-reliable use, why build that into your design?
All Relion batteries have built-in Battery Management Systems which maintain and balance each individual cell inside, guaranteeing you reliable performance for the entire battery lifetime. A single battery also lowers wire and installation cost (especially 24V vs 12V) and potential for loose connections.
Sized the same as a Group 8D Lead-Acid, it will fit most RV battery bays without modification and is easy to design space for. With the ability to deliver over 2500 Watts, it would pair perfectly with a 24V 2500W Inverter and 500-1000W of solar.
