Voltacase is a Dutch brand of portable batteries. It presents itself as a power supplier for camping, fishing and electric boating. Its batteries use lithium iron phosphate (LiFePO4) chemistry and feature a battery management system (BMS) that can be monitored via Bluetooth using an app.
The batteries come in 12 V cases ranging from 30 to 280 Ah and are supplied with a charger; some versions are waterproof. The brand also offers 100 and 200 W folding solar panels, electric cool boxes and Anderson connectors to link everything together. For anglers, a Voltacase case powers an electric motor and fish finder on a boat, and can be recharged by the sun during long sessions.
