These batteries require independent charging with reliable battery insulators or battery combiners. Onboard systems typically consist of two or more batteries that operate independently when powering 12 or 24 volt consumers. Battery clocks are used to monitor the condition of your batteries and are part of the store. Charge Mate is used to connect or disconnect two batteries. Battery splitters that split your charging current with minimal energy loss. Battery separators for conventional systems with alternator or battery charger and two or three batteries. The artificial end plates have connecting hoses, tight bolt connections with nuts and locking rings ensure easy installation. Diode voltage drop (about 0.6 volts) can be compensated by adjusting the output voltage of the charger or dynamo connected.
