The smartest control of a battery

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 over-discharge and deep discharge, which has a positive effect on the service life.

The battery for winter

The EFOY lithium battery works even in ice and snow, which is a clear advantage over all other lithium batteries. Commercially available lithium batteries cannot be charged in winter. Thanks to the integrated heating element, our EFOY lithium battery can be charged quickly and easily even at temperatures as low as -20 °C. That makes our EFOY lithium battery unique!

The EFOY lithium battery can handle your coffee maker

Powerful 230 V consumers such as coffee makers, hair dryers, kettles and many more draw high discharge currents from a battery. The EFOY lithium battery allows for high discharge currents and enables an inverter of up to 2,500 W to be connected.

Splashproof?
Of course!

The EFOY lithium battery is protected against splash water, making it ideal for marine use.

Safe LiFePO4 technology

With the EFOY lithium battery, we use proven and safe lithium iron phosphate technology (LiFePO4). Lithium cells are almost completely reusable and, unlike lead batteries, do not contain any environmentally hazardous substances.

The lightweight
among batteries

The EFOY lithium battery is a real lightweight due to its high energy density. Conventional 100 Ah lead or AGM batteries weigh around 30 kg. Our largest EFOY Li battery (105 Ah) weighs only 16 kg and thus only half as much. This saves weight!

Battery capacity virtually 100%

The EFOY lithium battery offers a larger battery capacity compared to lead or AGM batteries. This battery capacity can be used almost completely. This is extraordinary, because lead batteries can only be discharged up to 50 %. Use the full EFOY power reserve!
