Description

The 260 × 170 × 208 mm IP65 ABS case holds cylindrical LiFePO4 cells and the BMS, with M8 terminals. By volume that is 186.8 Wh/L, by weight 132.1 Wh/kg. The datasheet lists internal resistance of 1 mΩ and energy efficiency of 98%. The BMS cuts discharge at 10 V and charging at 14.8 V ± 0.1 V. Storage is permitted at −5 °C to +45 °C, and charging only above freezing, since this version has no heater. An 800 A peak is permitted for 300 ms, so a large inverter starts without tripping the BMS.

How to choose

If the battery will sit in the cold, take the PowerBrick Smart 12V-135Ah-BH of the same size with heating. A narrow bay suits the Blade 12V-135Ah-BT at 108 mm wide, and a smaller energy need the Smart 12V-100Ah-AB-BT at 1,280 Wh.
