+    * Raymarine i70: max number of tank levels is 5; fluid instance 0-4 and type must be fuel.
+    * Raymarine i70s: max number of tank levels is 5; fluid instance 0-4 and type must be fuel.

+==== LightHouse 4.1.75 and newer versions ====
+As of LightHouse version 4.1.75, the battery instances no longer need to be unique. This means that you can leave the battery instance to its default value, which is typically set to 0. The batteries are automatically detected by the Axiom display.
+==== LightHouse 4.1.74 and prior versions ====
 If there are more than 1 (for example) SmartShunts in the NMEA2000 network, or a Solar Charger and a SmartShunt, or any other device that transmits the same type of PGNs, then the Data instances of those PGNs need to changed to make each data instance unique.

-**Note**: this requirement of data instances being globally unique for a PGN is specific to Raymarine. Other brands do not require this. And, although perhaps besides the point, also the NMEA2000 standard does not require it. More specifically, it says: "Data instances shall be unique in the same PGNs transmitted by a device. Data instances shall not be globally unique on the network.".
