Anyone know if you switched out the regular lead acid 12v battery with a Lithium Ion, would it cause any problems? Would the Tesla charge it properly? Here are the batteries: 12 Volt Lithium Battery If I found one that fit the battery tray. Longer life, lighter. Would allow my four 12v cameras to run continuously. Just wondering if the Tesla would charge it properly and/or if there would be any issue with the warranty. From what I can find, these standard size lithium ion batteries are even more safe than the lead acid. Plus it will last the lifetime of the car unlike lead acid.
