Product category: Batteries


The energy supply with electricity must be effective and reliable. With a lithium battery from ECTIVE, you get powerful and reliable energy on the go. Lithium batteries can be used in almost all applications where lead acid, gel or AGM batteries are used.

Electrical energy storage is already playing an important role. In times of sustainability and climate-friendly energy generation, this will increase considerably. However, this requires reliable and powerful storage solutions - lithium storage batteries!

It is true that there are many different electrode materials that are used for this purpose. However, the so-called lithium iron phosphate batteries (= LiFePO4) also known as LFP for short, prove to be particularly effective and safe.

With our standard LC series you enjoy all the advantages of a LiFePO4 battery. Our two other series have even more advantages that you might like.

Our LC series lithium batteries already incorporate a lot of innovation and clever technology with the battery management system. With the BT models of the LC series, it gets even more sophisticated. Under the hood of these models, a Bluetooth module ensures that you can keep an eye on all the relevant information about your battery at all times.

Get the ECTIVE app on your smartphone (available for free for Android and iOS) and connect to your lithium battery in seconds. Bluetooth technology requires no line of sight and works within a range of several meters. This is especially handy if you have installed your battery in a somewhat hard-to-reach place.

All the important information lands on your smartphone in real time. In addition to the current state of charge and voltage, you also get information about the temperature, the number of cycles and much more.

The LT (Low Temperature) models of our lithium batteries solve a problem that many of you have told us about time and again: Cold. At temperatures below 0°C, ordinary lithium batteries can no longer be charged. For those who like to travel in winter temperatures, are fans of winter camping, or operate a solar system during the colder months, this can be a real problem.

Problem solved! Our LT models can be charged at temperatures as low as minus 30 °C. Otherwise, they have the same outstanding features of the LC series and also have the useful Bluetooth module.

We wish you a lot of fun on your next winter trip with your camper or wherever you like it cooler and want to use an ECTIVE lithium battery for power supply. Just look for the little snowflake on the label of the battery, because it makes the small but subtle difference.
