When installing the DC-DC charger, are there any precautions I need to be aware of?

First, installing the charger vertically will improve venting and heat dissipation of the charger. Additionally, positioning the DC-DC charger nearer the service battery is advised.

Can the battery be charged with both the solar and the alternator at the same time?

The DC-DC charger will choose the DC input automatically rather than charging the service battery with both the solar and DC inputs.

Can LiTime 12V 40A DC-DC charger activate the low voltage LiFePO4 battery?

YES, LiTime 12V 40A DC-DC has a lithium battery activation function, but the battery needs to be disconnected from the load for activation.

Should I add breakers (fuses) when using a DC-DC charger?

YES, it is strongly advised. It is suggested that a breaker be installed between the DC-DC charger and the starter battery.
