If you are using a Skylla-i or an MPPT with a CAN bus in the system, the CAN bus will be powered through one or the other. If the CAN bus is not powered by a Skylla-I or an MPPT, you will need the new VE.Can cable for power.
Battery alarm: an affordable device to monitor your battery
The battery alarm is a small, economical control panel for monitoring your battery's status. It is equipped with audible and visual alarms, as well as a dry contact.
By using ARGO FET splitters, it is not necessary to also increase the alternator's output voltage. It is still advisable to use short cables with a sufficiently effective cross-section.
FET splitters are like electricity separators that allow multiple batteries to be charged with a single charger, without having to connect them together. Thus, if you use one battery for something, it will not affect the other charged batteries.
