Up to 95% usable capacity with 2% low self-discharge and low capacity loss. More energy per charge means longer runtime and less “power anxiety” during trips or off-grid use Automotive-Grade cells + 200A BMS deliver stable 2560Wh energy. Built-in protections reduce safety risks, so your RV/solar loads run reliably without outages. 20+ BMS protections (overcharge/over-discharge/over-current/over-heat, etc.) actively safeguard the battery. Prevents damage under daily cycling and helps extend overall battery lifespan. 51.61Wh/lb energy density packs 2560Wh into ~55 lb - about 3X lead-acid energy density. Lighter installs and higher efficiency where weight and space matter. Flexible expansion: connect up to 4 in series (48V) or 4 in parallel (800Ah). Scale your bank for RV, marine, solar, home backup, and off-grid needs. Product Details Manufacturer Power Queen Model 12V 200Ah PLUS Size 12.8V200Ah PLUS Quantity 1
