Interesting technology. I read about Ti and Aluminum making their way into batteries a number of years ago but never kept track. The expanded temperature range for charging certainly introduces new applications, starting battery included.

Ok, I interpreted their information inaccurately regarding low temperature charging. Went back and looked within FAQ and this battery still shouldn't be charged below freezing. Makes it limited being marketed as a "starting battery" IMO.

snip from their FAQ: "We also do not recommend charging our batteries below freezing temperatures. If you are planning to regularly charge your battery below freezing temperatures we recommend the DL+ 12V 135Ah battery which has an internal heating element and is optimal for use in cars, trucks, RVs, off grid solar, and any application where the battery will be charged regularly in extremely cold environments (like a North Dakota winter)."

The various lithium battery formulations have different fire risks associated with them. I couldn't find any fire risk data on this formulation.

It may be something barely above non-zero. The Ti is already oxidized if the name/label is chemically correct. That reduces the fire potential significantly. (Pun not intended.) If the Ti isn't already oxidized then there is a significant fire potential. Machine shops that work with Ti or Magnesium need to carry specific additional fire insurance as because of their exothermic properties those two metals are usually exempted from the normal industrial fire coverage.

Would this reactivity be an issue in use or in the manufacture of the battery? Just curious. This is a new battery technology (to me) and I hate the lead acid battery used as my starter battery. If I can find a battery with more power/lifespan that my alternator can charge as-is I'd probably replace my current one.

I see a listed maximum charge voltage but not seeing any recommended charge voltage perimeters. Given all the smart alternators in vehicles these days it gives me pause how they are getting sufficient charge voltage & associated perimeters from just a BMS.

Since I don't know the chemical rxn happening in the battery I really don't know. If the Ti is always TiO, then it shouldn't be a problem.

Interesting that Dakota offers 11 year warranty

There is also these guys offering drop in lto
