Datum: Published installed enclosure envelope lower corner at the origin; +X is 137 mm length, +Y is 62 mm width, +Z is 33 mm height.
The solid is the installed envelope from the current manual, not the downloadable manufacturer enclosure assembly, which is posed with its lid open. Terminal access, wire bend radii, mounting clearance, fusing, parallel-panel blocking diodes, and thermal installation remain consumer-owned. The 14.6 V Li-CV setpoint must be ordered as a factory custom configuration; the 95–97% efficiency and 7 mA standby facts are the manual's closest standard 4S LiFePO4 profile and require supplier confirmation for the custom firmware before qualification.
