What are your charge and discharge low AND high temperature shutoffs?
How are you managing for temperatures outside the limits?
What other mods/equipment/monitors required to charge/monitor/maintain your Li from alternator, solar, and/or shore?
How are you charging/maintaining your starter battery bank with mixed battery chemistry. Have you changed your starter battery to Lithium, too?
Don't get me wrong, I have just switched our house bank to two SOK 206Ah Lithiums plus many additional components to match up to this system as well as manage for temperature issues. Not simple, not easy, and certainly not cheap.
A full eval needs to be done on a person's USAGE profile. If you are a winter user or high temp desert user you better know your stuff or you could be 100% shutdown with NO Lithium battery power in a critical situation. Will not matter that you can charge 4,000 times. And I am not so sure that these Lith batteries will actually live up to their cycle specs in the usage profile we put them in. These Li batteries really do not like the "use and charge at the same time" and top off storage profiles of an RV setting. The cycling profile of the tests are not the same as how they are used in our rigs.
My Iphone 6S has gone through three batteries in its life which is far less than five years. It has shut off in the cold and when hot. Just some considerations.
