Sorry, we cannot yet say whether this alternator actually works in a temperature-compensated manner. We have forwarded your question to our supplier. As soon as we have the relevant information, we will answer immediately. ///\\\ Here are some basic thoughts on charging lithium batteries with a standard alternator: 1) Please remember that alternators are designed to charge lead-acid battery types and even then they are not suitable for reliably and fully charging deep cycle consumer batteries without additional charging technology. Lithium batteries have a lower internal resistance than lead-acid battery types, which is why they can draw very high currents and also stress the alternator thermally. This is especially true at lower engine speeds. At low engine speeds, the alternator also runs at lower speeds, which also reduces the air flow of the alternator fan, resulting in less cooling of the alternator. 2) To fully charge lithium batteries, a constant voltage of 14.6 V is usually required (check your lithium battery manual). Think about using a battery-to-battery (B2B) charger. Most of these devices have a lithium characteristic and, if selected correctly, can also be used as a current limiter to protect the alternator from thermal stress.
