Description
Cells and BMS sit in a 260 × 168 × 212 mm IP65 ABS case with M8 bolt terminals. Balancing at up to 1 A evens the cells in service, and Bluetooth shows every cell voltage, so imbalance is caught before it eats capacity. The pack gives 1.92 kW continuously and 3.0 kW short-term, and takes a 350 A starting peak for 300 ms. The BMS ends charging at 29.4 V and discharge at 20 V. Specific energy is 123.1 Wh/kg, and internal resistance stays at or below 50 mΩ.
How to choose
On a 24 V bus the choice comes down to stored energy and the need for state monitoring. The PowerBrick Pro 24V-32Ah skips Bluetooth and is lighter, 819 Wh at 6.8 kg. For 3,840 Wh in one case take the 32.0 kg PowerBrick Smart 24V-150Ah-AB-BT.
