This, in turn, controlled a 12v Coil VF4 SPDT relay to turn a 12V 30W heat pad on/off, that was placed under the batteries. As the Venus GX uses resistance for its tank levels, Chris used this to control one of the Venus GX relays. This being an issue, Chris thought outside the box and used the resistance properties of a Venus GX to measure the temperature of the battery box, which in turn controlled a relay.Ĭhris used a PT100 temperature probe inside the battery box, between the batteries, which is a resistance probe. The main NMEA 2000 & MFD integration guideĬhris Dobson (seen in the video above) loves problems and is very keen to solve them, especially ones such as – lithium don’t like to be charged below 5C.
