Description

The 180 × 76 × 168 mm ABS case is sealed to IP65 and holds cylindrical cells, with M5 bolt terminals on top. The built-in BMS stops charging at 14.8 V ± 0.1 V and drops the load at 10 V, so the pack cannot be over-discharged. A peak of 180 A ± 30 A for up to 100 ms covers the inrush of an inverter or motor. Internal resistance is 50 mΩ or less, specific energy 111.3 Wh/kg. Store it at 0 °C to +50 °C. Energy efficiency is above 96%, so nearly all the charging energy comes back out.

How to choose

In the same case the PowerBrick Pro 12V-30Ah gives 384 Wh at 3.44 kg. Alarm panels and cameras get by with the Pro 12V-7.5Ah at 96 Wh or Pro 12V-12Ah at 153.6 Wh, and above 256 Wh look at the PowerBrick 12V-40Ah at 512 Wh or Pro 12V-45Ah at 576 Wh.
