Model-specific notes: This entry uses the 4U variant only; a separate 3U product has different dimensions. Parallel quantity follows the February 2026 datasheet rather than older 40-unit literature. Supplier photo obtained from https://www.leoch.com/products/lithium/residential-rack-mounted-battery and edited only to remove the brand mark. Cycle life is a stated test condition, not a site-life guarantee.
