Power supply for weekends
EFOY Li 70
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.
Our EFOY products meet the highest quality standards. That’s why we offer a full 5-year manufacturer’s warranty on our EFOY Li batteries free-of-charge. For maximum safety and freedom on your adventures.
The required total output of the lithium battery depends on the amount and demand of the power consumers in the motorhome, sailing boat, garden cabin or camper. The TV in a motorhome has an output of around 25-30 watts. First check the values of all consumers to be operated. Then calculate the amperage using the following formula:
Power in watts (W) / voltage in volts (V) = current requirement in amperes (A)
You do this for all the loads you want to operate and add up the current requirement. You should also imagine the time for which the devices are to be supplied with power. Then calculate the power requirement for your camper using the following formula:
Current in amperes (A) x time in h = current per day in ampere hours (Ah)
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!

You want even more power? With EFOY Hybrid Power, you’ll be on the go without worries and have power at all times. EFOY Hybrid Power combines our environmentally friendly fuel cell with the efficient EFOY lithium battery.
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.
The EFOY lithium battery is protected against splash water, making it ideal for marine use.
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 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!
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!
