PowerBrick Blade 12V 135Ah LiFePO4 battery with Bluetooth, slim case

Technical specifications

Specifications, charts and drawings are taken from the manufacturer’s technical documentation. Updated 10/31/2026. Customs codes are for reference only; the final code is determined at customs declaration for the specific model.

Description

The 395 × 108 × 287 mm size suits tight bays where a regular block of the same capacity will not pass in width. The ABS case is sealed to IP65, with M8 terminals and cylindrical LiFePO4 cells plus the BMS inside. The datasheet gives internal resistance of 1 mΩ and 98% efficiency. Charging is permitted at 0 °C to +55 °C, storage at −5 °C to +45 °C. The BMS drops the load at 10 V and stops charging at 14.8 V ± 0.1 V, and specific energy is 129.1 Wh/kg and 141.2 Wh/L.

How to choose

The same capacity in a compact 260 × 170 × 208 mm case is the PowerBrick Smart 12V-135Ah-BT at 13.1 kg, and the Smart 12V-135Ah-BH adds heating. The Blade is the pick when bay width decides, not length or height.
