Lovely ep and set ups

Good set up. Was it a simple thing to change the Toyota inverter and interior USBs over to the victron set up? Vic high country with batteries at 45 deg is ok. How will this go back in Qld or nth Qld or NT or the desert areas? I see these batteries are rated to 110 deg so I doubt they would be an issue. However, can they sustain the very high desert type temps when slow low range through sand dunes or similar. I guess the life expectancy will be reduced a reasonable amount. ### I just watched your French Line video where you had battery temps up to 76 deg which is just what I was asking about above. As you said your batteries will do those types of temps but at a life span cost. That was a very good and informative video thank you. Do you think that the battery temps would have been much less in a 300 Series?

Yes the access is pretty good in the LC300's. Pretty easy to do. When we first started doing this back in 2015, LFP as a cell chemistry wasn’t anywhere near as advanced as it is today - we can optimise the cycle life, tempereture stability and C rate triangle. But even back then LFP was a superior deep cycle cell chemistry and put AGM for example to shame under high temperature applications. More info here from 2017: www.deepcyclesystems.com.au/the-ultimate-dcs-12v-dual-battery/ Today LFP is the superior cell chemistry for every environment under the sun nothing comes close in 2024 that gap is twice as wide in comparision. So ambitent temperatures up to 80 degrees C is no longer a factor for us, as there is little effects on cell chemical ageing under 80 degrees C. Please note our Battery Management System will run up to 110 degrees C. The cells are not allowed to charge above 80 degrees C, that is tightly managed by the BMS and 2 independent battery cell temperatures, to ensure utmost safety and reliability, which our customers have grown accustomed to. The LC300 is unique its the coolest running engine bay we have ever come across on any 4WD in the world. Mainly attributed to the fact that it's a 'cold' running motor the coolant thermostat is set at 76 degrees C, and ontop of that the turbos have their own dedicated liquid cooling system and after cooling.

Nice place, i was camping there on the river last week. How was Billy goat bluff track we heard it was bad so didn't do, to many in the convoy.

Yes it's a nice spot, we had done this trip back in Nov 2023, Billy Goat Bluff Track was fine back then, no idea what it's like now...
