Not that one, but did replace the 12v battery with a lithium battery. Factory battery is a 65ah 500cca agm. This is a 40ah lifepo4 battery designed for medical devices. They both have roughly the same amount of power since the agm has ~50% discharge verses 80%for this one. The lithium has a much better discharge curve giving higher voltage and quicker charge/discharge . It also saves almost 40lbs of weight. I'm hoping between reduced duty cycle of the dc-dc inverter and the weight savings I'll see some mpg improvements but probably not. Either way fun to say ive got a lithium ion powered LS 😁

 

How’s your lifepo4 been behaving? Definitely on my list of todos for when I get 12v battery issues with my nxh.

 

How's the Lithium 12V battery working in your LS460? I think Lithium is great, except that it has limitations for charging below 32F, actually below 40F I believe.

If you live in a relatively moderate area, Lithi 12V would work ok IMHO. But in a very cold climate area, with long cold winters, you may suffer low charging of the 12V battery, and not have enough power to start your car.

 

Haven't noticed any measured difference in performance but it's working great.
