How does the HYMER Smart Battery System work?

The HY-Tec lithium battery 150 (LiFePo4*) consists of 6 individual LE300 lithium extension battery modules (LE300). This extendable solution increases the capacity and performance of the lead batteries, while simultaneously increasing the efficiency and lifespan of the entire system. The lithium batteries are connected in parallel with the lead batteries. The lithium batteries undertake the majority of the charging cycles, while the lead batteries function as backup storage devices.

*Lithium-iron-phosphate safe and robust lithium technology

This is how the charging cycle of the Smart Battery System works:

  1. The system ensures that the lead batteries are charged first.
  2. Any excess energy is stored by the lithium batteries.
  3. Conversely, when power is consumed, the lithium batteries are discharged first, significantly increasing the lifespan of the lead battery.
  4. Thanks to integrated discharge management, the lithium batteries detect the voltage of the lead battery. The on-board power supply system is thus preferentially powered by the cycle-proof lithium batteries. In the event of increased energy consumption, power is supplied by the lead and lithium batteries in parallel, so that there is less strain on both batteries.

The result: A reliable and stable power supply on the road, especially when there aren’t any external power sources nearby.

What are the advantages of the HYMER Smart Battery System?

With a service life of 10 years, lithium batteries offer a significantly longer lifespan than standard lead batteries (approx. 3 years). If used optimally, the HYMER Smart Battery System will also increase the lifespan of your lead battery.

Battery efficiency is also increased by as much as 80% (normally 50%). Compared to conventional lead battery systems, this results in increased self-sufficiency while simultaneously reducing weight.

The prices can be found in the optional extras for each model range.

  • Increase in self-sufficiency from 1.4 days to as much as 10.5 days at the typical rate of use

  • Weight saving of at least 5 kilograms with almost double the capacity

  • Considerable cost savings versus comparable lithium and lead battery systems

  • Increase in the battery lifespan

  • Winter-proof overall system

  • Improvement in battery efficiency (from 50% to as much as 80%)

  • No special charging technology required

  • Available for all HYMER motorhomes and HYMER camper vans

HYMER Smart Battery System also available for retrofitting

Enjoy even more self-sufficiency with the powerful HYMER Smart Battery System for retrofitting from HYMER Original Parts & Accessories. Suitable for HYMER motorhomes and HYMERCAR camper vans from model year 2015 onwards. The HYMER Smart Battery System is available in two retrofit packages.
