Operation:

Using this relay it is possible to charge 2 batteries simultaneously . When the engine is started and the starter battery reaches a voltage of 13.3V, the relay connects the 2 batteries in parallel (starter and secondary) which are then charged simultaneously . When the voltage drops below 12.8V (for example when the engine is switched off ), the relay is disconnected and the two batteries are separated. This system This prevents the starter battery from being discharged and protects sensitive electronic equipment connected to the secondary battery from voltage peaks that may occur, for example, when starting the engine. The intelligent electronics switch the relay , for example , when charging the secondary battery from a solar panel, thus enabling the starter battery to be recharged as well.
