The very first 26V MPS battery to be made available. Note that the product name of this battery is based on its installed capacity @C2 (read: the maximum amount of energy available for discharge over a 2-hour discharge period), while all other MPS battery product names are based on capacities @C10. Technically, this battery therefore has the same kWh capacity as the top-selling BN13V-108-1.4k model, but at double the voltage.
