Hymer Cooperation



Build to discover the mobile world



Together with Erwin Hymer Group, the BOS AG has enabled thousands of people to explore millions of worry free miles. A smart alliance has been successful in developing a battery solution which is tailormade to the requirements of achieving independence in a caravan.

A smart upgrade from traditional lead acid batteries to lithium batteries

Many caravan and RV owners shy away from upgrading their traditional lead acid battery system to lithium batteries. But why? Because it is expensive, involves replacing the charging systems and adding complex electronics, and expensive installations. Moreover, there are only few lithium solutions on the market which suit RVs and caravans.
Realising this oppotunity, BOS together with Hymer formed a cooperation where BOS would build a plug and play lithium battery solution which is easy to install, does not need any electronics to be replaced or changed, is modular, inexpensive, and made in Germany. From this alliance the LE300 was born. The only battery for caravan application with E1 certification. This certificate allows batteries to be installed in automotive applications in Europe. The LE300 is designed to last more than 10 years, extend the life of lead acid batteries and its battery capacity can be expanded when needed. In the last 5 years of cooperation, the product has been succesful in delivering its promises to thousands of campers and caravan owners with over 40,000 LE300 sold. The LE300, also known as Erwin Hymer Group smart battery system, has been offering more freedom of energy and independence in travel. 

Thanks to the significant higher self sufficiency and integrated battery heating, campers are able to stay at beautiful places much longer, even in winter. The system is installed as standard in select models and can be retrofitted in all Erwin Hymer Group caravans. The alliance has launched a new smart lithium battery system, known as BOS battery S. We are expecting the BOS battery S to further solve the energy problems of campers and help them enjoy many more miles.
