As long as the voltage does not drop below 13.2v, this would be the absolute minimum voltage for running lithium batteries directly from the alternator.

Tim,off topic,how do they go with LC200 as it sits pretty low most of the time,under 13.5V?
There are heaps running around with dual lithiums and no booster diode?

Hi Paul and this is part of the problem.

Most vehicles today have some form of SMART alternator operation, where the vehicle’s electronics monitors the cranking battery in some form.

BUT Toyota’s do NOT have SMART alternator operation.

They have a much simpler Variable Voltage operation, which does not actually monitor the battery.

Toyota’s Variable Voltage operation will accomodate the use of lithium batteries.

But any vehicle equipped with SMART alternator operation, unless you can turn off, disable the SMART function, you can not use a lithium cranking battery and must use a DC/DC device to charge any lithium auxiliary batteries.

To date, I have not come across any means to deactivate the SMART alternator function in any late model Land Rovers.
