PowerBrick Smart 12V 70Ah 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 228 × 138 × 210 mm ABS case is sealed to IP65, with M8 bolt terminals and cylindrical cells. A 100 A continuous rating means 1.28 kW, and 150 A for 30 s gives 1.92 kW. Internal resistance is no higher than 40 mΩ, energy efficiency above 98%, specific energy 110.6 Wh/kg. The BMS ends charging at 14.8 V ± 0.1 V and discharge at 10 V. Storage is fine at 0 °C to +50 °C. LFP chemistry accepts partial cycles, so long float duty in a UPS does not harm it.

How to choose

It suits a camper, boat or small UPS where 896 Wh is enough and weight matters. For more energy, the Smart 12V-100Ah-AB-BT with the same balancing gives 1,280 Wh at 11.3 kg, the Smart 12V-135Ah-BT 1,728 Wh at 13.1 kg.
