EFOY lithium battery with smart battery management system
The EFOY lithium battery (LiFePO4) is the ideal entry point into an off-grid energy supply. The smart battery management system (BMS) constantly monitors the battery parameters to optimize efficiency and protect the battery. The battery is thus ideally protected against overcharging and deep discharge, which has a positive effect on the service life.
The intelligent energy package
EFOY Hybrid Power is a perfectly coordinated energy package consisting of an EFOY fuel cell as a power generator and an EFOY lithium battery as a power storage device. 100% self-sufficient, environmentally friendly and quiet. The smart BMS of the EFOY lithium battery ensures intelligent communication between the fuel cell and the battery. In this way, the EFOY fuel cell works with 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.

The ideal battery for cold temperatures
The EFOY lithium battery also works at low temperatures. Commercially available lithium batteries cannot be charged in cold temperatures. Thanks to the integrated heating element, it can also be easily charged at temperatures down to -20 °C. This is what makes our EFOY lithium battery unique!
Splash proof
The EFOY lithium battery is protected against splash water and is therefore ideally equipped for extreme environmental requirements.
High energy capacity at low weight
We rely on proven and safe lithium iron phosphate technology (LiFePO4). Compared to conventional lead batteries, the EFOY lithium battery has a high energy capacity and is lightweight. It can also be discharged up to 100%.
Ideal for high peak loads
Heavy loads often load a battery with high peak currents. Compared to the competition, the EFOY lithium battery is ideally designed for this.
