EFOY Li 70
The ideal introduction to your independent power supply
Technical Data EFOY Hybrid Power
The EFOY Lithium Battery is the ideal way to start using an off-grid power supply. The smart Battery Management System (BMS) continuously controls the battery parameters in order to optimise the battery’s efficiency and to protect it. The battery is thus ideally protected against overdischarge and deep discharge, which has a positive effect on the service life.
EFOY Li 70
The EFOY Lithium Battery works even at low temperatures. Commercially available lithium batteries cannot be charged in cold temperatures. Thanks to the built-in heating element, it can also be charged even in temperatures down to -20°C.
The EFOY Lithium Battery is protected against splash water, making it ideal for extreme ambient requirements.
We rely on the proven and safe lithium iron phosphate technology (LiFePO4). Compared to conventional lead batteries, the EFOY lithium battery has a high energy capacity with a low weight. In addition, it can be 100% discharged.
Heavy consumers often stress a battery with high peak currents. The EFOY Lithium Battery is ideally designed for such consumers.

EFOY Hybrid Power
EFOY Fuel Cell + EFOY Lithium Battery
EFOY Hybrid Power is a perfectly matched energy package consisting of EFOY fuel cells as power generators and EFOY Lithium Batteries as power storage. 100% autonomous, environmentally friendly and quiet. The smart BMS of the EFOY Lithium Battery ensures intelligent communication between the fuel cell and battery. This way, the EFOY fuel cell works at maximum efficiency and the battery benefits from ideal charging, special protection and a long service life. And you benefit from a particularly powerful and efficient energy supply – simply intelligent.
