Expecting restock
A specialized external battery module, designed to expand the capacity of powerful charging stations in the OUPES Mega 1/2/3 series. It is not a fully independent power source in the classic sense, as it does not contain a built-in AC inverter, but serves as an additional link that addresses the task of energy storage. Positioned as a mid-priced product, it is purchased by users of OUPES Mega charging stations to enhance autonomy. The operation principle of the OUPES B2 Extra Battery module is based on the technology of parallel or sequential interfacing with the main device through a proprietary interface. The module transmits the accumulated direct current from the battery cells to the main station, which in turn converts it into alternating current (AC, 230V) or distributes it th...rough USB and DC ports. When connected to the main device, the system recognizes the module as an extension of the internal battery, summing the available capacity. The nominal capacity of the device is 2048 Wh. This model uses lithium iron phosphate (LiFePO4) cells, ensuring high energy density while adhering to safety standards. Thanks to the module's own DC ports, it can be used independently even without connecting to the main station.
