Separator

Disconnection relay to protect the battery before unloading

The use of a separator is recommended for two reasons: on the one hand, it enables a battery to be charged while driving, on the other hand, it protects the starter battery from unloading. A separating relay only connects two batteries when the engine is running with a loading alternator. In addition, a dividing relay becomes necessary if two different battery types have been installed in the vehicle's board network, such as lithium (LTO or LIFEPO4) and a lead AGM battery. Since different battery types have different resting stresses, this would lead to mutual discharge. This effect can be prevented with the help of a dividing relay..
