Lithium batteries

I am considering making the investment in a house bank of lithium
batteries. When talking around I hear that the regulator should have
a temp sensor for the alternator as these batteries will accept full
current quite a bit longer than a lead acid. I've heard more than one
story of toasted alternators.

I've had one of your early multi step controllers on the boat since
the mid 90's and it has worked fine, and would like to continue to
support your company. I don't see any of your products that are
monitoring the alternator temp. Am I missing something?

What is your take on charging a 320AH bank of lithiums with a 130A

Some vendors provide alternator temperature control with their alternator regulators. In fact all automotive alternator have alternator temperature fold-back of current, the predominant reason their output quickly declines to "slow charge".

Our alternator are designed so they don't need fold-back regulation. Admittedly, they don't look as nice as painted alternators, but paint is an insulator that prevents good heat conduction from the alternator.

Short answer: Charge!
