Description

The 260 × 170 × 208 mm ABS case is sealed to IP65, with M8 terminals and cylindrical cells, the BMS and a heater inside. The datasheet permits charging at −20 °C to +55 °C, discharge at −20 °C to +60 °C and storage at −5 °C to +45 °C. Internal resistance is listed as 1 mΩ and energy efficiency as 98%. The battery management system ends charging at 14.8 V ± 0.1 V and discharge at 10 V. Specific energy is 132.1 Wh/kg and 186.8 Wh/L, dense both by weight and by volume.

How to choose

Unheated rooms and outdoor cabinets call for this version, while a warm switch room can use the same-size PowerBrick Smart 12V-135Ah-BT. A narrow bay takes the Blade 12V-135Ah-BT at 395 × 108 × 287 mm, and more energy with heating comes in the Smart 12V-150Ah-BH at 1,920 Wh.
