Description

The ABS case is sealed to IP65 and houses cylindrical cells and the BMS, with M5 bolt terminals. A 40 A continuous rating means a 512 W load, and for 30 s the battery pushes 70 A, or 896 W. It survives a start-up pulse of up to 180 A ± 30 A for 100 ms. The BMS cuts discharge at 10 V and charge at 14.8 V ± 0.1 V. Specific energy is 111.6 Wh/kg and 166.2 Wh/L, internal resistance up to 50 mΩ. It can be stored at 0 °C to +50 °C, and energy efficiency is above 96%.

How to choose

The case matches the PowerBrick+ 12V-20Ah with 256 Wh, so moving up to 30 Ah keeps the same mounting. Low-current security circuits get by with the Pro 12V-12Ah at 153.6 Wh, and 512–576 Wh in one unit means the PowerBrick 12V-40Ah or Pro 12V-45Ah.
