Knox 7.68kWh Lithium-ion Battery 51.2V (Rackwall 8.0)

Note: Knox rate the Rackwall range at a 90% depth of discharge and quote cycle life at that same 90%, down to 80% of initial capacity - a materially stronger claim than the Powerwall range, which is quoted at 80% DoD to 70% capacity. Same >6000 cycles, deeper discharge, stricter end-of-life threshold. 150 A continuous both ways - a full 1C - with a 180 A pulse for 2 seconds. Standard 19-inch rack design with quick-lock press-to-release terminals, a 4.3-inch touch LCD that lets you switch inverter protocol on the screen, and RS485 plus CAN for the inverter with LINK-IN/LINK-OUT for battery-to-battery chaining. Charging window 55.2-57.6 V, end of discharge 48 V. Parallels to 15 sets; series is not supported. 10-year design calendar life. IP20, so indoor or cabinet only. 65 kg in a 175 mm-high chassis, so it takes 4U of rack space. The entry point of the Rackwall range and the natural step up from the wall-mounted Powerwall 6.11 if you are building a cabinet rather than hanging units on a wall.
