Description

Outside is a 260 × 168 × 212 mm IP65 ABS case with M8 bolt terminals, inside are cylindrical cells and the BMS. At 50 A it puts out 2.56 kW, at 100 A up to 5.12 kW, and it takes a 270 A inrush for 100 ms. The BMS cuts discharge at 40 V, and 50 mΩ max resistance holds voltage up under load. Specific energy is 107.6 Wh/kg and 138.2 Wh/L. IP65 lets you mount it in a damp basement, on a boat or in an outdoor cabinet, with no protective enclosure required.

How to choose

Start from the energy for the backup time and the continuous current. If 2.56 kW is short, the PowerBrick Pro 48V-32Ah in the same case holds 1,638 Wh, and the PowerBrick Smart 48V-72Ah-BT and PowerBrick Smart 48V-105Ah-AB-BT give 3,690 or 5,380 Wh. A bank of several of these is easy to install, as one person carries each.
