Seat Series +Battery Expansion Capability. Where You Sit. Bolt the +Battery Expansion directly onto your Seat Series Platform—the core foundation of the Seat Series—to transform wasted under-seat space into a secure, vibration-proof auxiliary battery mount. Deep in the woods, night settles in. The fridge hums softly through the dark hours, keeping food fresh while you rest under the stars. At dawn, coffee brews on the induction cooktop—no propane hassles, just reliable auxiliary power. Your Jeep starts strong—crisp, immediate. No hesitation. No ruined plans. That's the quiet confidence this +Expansion delivers. Modern off-road rigs face heavy electrical loads: bright off-road lighting, powerful GMRS radios, fridges, winches, compressors, inverters, and more. +Battery mounts the proven Odyssey ODS-AGM16L (PC680) or similar compact battery under the seat—hidden, secure, vibration-proof—so your gear draws from a dedicated source. Starter battery untouched. Adventures stay reliable and modular.
