The EFOY lithium battery with integrated heating element also works in cold, icy and snowy conditions and can therefore be charged at sub-zero temperatures down to -20 °C. This is a clear advantage over other lithium batteries, which can only be charged from +0 °C. The integrated smart battery management system (BMS) ensures that the parameters of the EFOY lithium battery are controlled and optimised fully automatically. The battery is thus ideally protected against overcharging and deep discharge.

In combination with an EFOY fuel cell, a self-sufficient power supply can be created in the motorhome, on board and when travelling. The optional Bluetooth adapter enables control via the EFOY app from a mobile phone or tablet.

Rated voltage 12 volts. Splash-proof according to IP44. Connection via M8 pole terminal

EFOY Fuel Cell
Maximum flexibility and independence: with its innovative EFOY series fuel cells, the German manufacturer SFC ENERGY offers a weather-independent and environmentally friendly energy source - space-saving, lightweight and absolutely quiet.The device contains the necessary charging electronics and switches itself on or off automatically as required depending on the condition of the batteries, the battery is always fully charged and deep discharging is prevented.The EFOY fuel cell is based on DMFC (direct methanol fuel cell) technology. It converts chemical energy into electrical energy without intermediate steps and major efficiency losses. Electricity is produced using the fuel in the fuel cartridge (methanol), supplemented with oxygen from the air. In addition to electricity, only waste heat and water vapour with a small amount of carbon dioxide are produced. Efficient and exceptionally environmentally friendly!Further features:compact & maintenance-free,with Bluetooth interface for control & monitoring,Compatible with other power sources such as solar panels or wind generators,suitable for all battery types with 12 volts and 24 volts,Quick change of the fuel cartridge,Nominal consumption/kWh: 0.9 litres,Protection class IP21,Application range -20 to 40 °C.Scope of delivery EFOY 80 BT and EFOY 150 BT:Fuel cell, service fluid, waste heat elbow, insulated exhaust hose, belt clip, charging cable, outer panel, waste heat pipe, Bluetooth adapter, fuel cartridge holder incl. beltFuel: The fuel cartridges are filled with high-purity methanol. The safety cap prevents contact with the fuel and the cartridge can be replaced in seconds. 5 litre fuel cartridges (total capacity 460 Ah, electr. nominal capacity 5.6 kWh) or 10 litre fuel cartridges (total capacity 925 Ah, electr. nominal capacity 11.1 kWh) are available.Demo system:We have the EFOY 80 fuel cell in operation as a demo system in our shop. We will be happy to explain the mode of operation to you here.
