Description

It connects with 6.35 mm Faston terminals, like the lead-acid batteries of alarm panels. The IP65 ABS case holds cylindrical cells, and the BMS inside drops the load at 10 V and ends charging at 14.8 V ± 0.1 V. The 24 A continuous rating gives 307 W, 30 A about 384 W, and a pulse of up to 140 A ± 20 A is permitted for 100 ms. Specific energy is 118.4 Wh/kg, internal resistance no higher than 50 mΩ. Energy efficiency is above 96%, and storage temperature is 0 °C to +50 °C.

How to choose

Choose it when 7.5 Ah is too little and a bigger case will not fit. The smaller PowerBrick Pro 12V-7.5Ah with 96 Wh fits 151 × 65 × 92 mm, and one step up are the PowerBrick+ 12V-20Ah at 256 Wh and the Pro 12V-30Ah at 384 Wh, both with bolt terminals.
