Battery technology High-performance and safety: Torqeedo LIMA cells 300 Wh LIMA high-performance batteries are integrated in the Torqeedo Travel models Lithium-based battery systems are by far the most powerful energy carriers currently available. On the one hand they are characterised by a high specific energy density. This means that they are able to store a large amount of energy per kilogram of battery weight. In addition, lithium batteries can withstand high current: in other words, they are able to deliver their capacity even under high loads. Both of these characteristics are of great importance for applications in boat drives: on the one hand, the battery weight and volume on board is reduced. On the other hand, the lithium-based battery systems ensure that the power supply does not collapse even when the boat's electro-motors temporarily draw high currents from the batteries. An additional advantage: lithium batteries do not display a memory effect and are cyclically stable. Even when stored for many months, almost no charge is lost, in contrast to conventional lead batteries. Torqeedo lithium cells are also extremely robust and are secured against incorrect handling. In addition, they are protected against short-circuiting, overvoltage and excessive discharge.
