PowerBrick Smart 12V 250Ah LiFePO4 battery with Bluetooth and active balancing

Technical specifications

Specifications, charts and drawings are taken from the manufacturer’s technical documentation. Updated 10/31/2026. Customs codes are for reference only; the final code is determined at customs declaration for the specific model.

Description

The 500 (520) × 239 × 217 mm ABS case is sealed to IP65, with M8 bolt terminals, cylindrical cells and a BMS with an active balancer inside. The 180 A continuous rating gives the load 2.31 kW, and 250 A for 30 s up to 3.2 kW. It accepts 125 A of charge current, so a strong charger refills it in a little over two hours. The BMS ends charging at 14.8 V ± 0.1 V and discharge at 10 V. Specific energy is 115.1 Wh/kg, efficiency above 98%, storage at 0 °C to +50 °C.

How to choose

On 12 V this is the most energy in one case, beyond that the bank grows in parallel. If that much is not needed, the PowerBrick Smart 12V-150Ah-BH gives 1,920 Wh at 15.8 kg, and the Smart 12V-100Ah-AB-BT with the same active balancing 1,280 Wh at 11.3 kg.
