The battery presented in @Mustangman posting is not a Lithium-Ion (Li-ion) battery, it is a Lithium Iron Phosphate (LiFePO 4) battery. There are Pros and Cons to these batteries… LiFePO 4 batteries can be cycled many more times than a Lead Acid Battery and could last 10 or more years… but they do not perform well in cold climates. The LiFePO 4 battery does not contain the toxic ingredients of a Lead Acid Battery. A LiFePO 4 battery is also much lighter than a lead acid battery. There are many other differences and some may be important to the various users and the higher upfront cost compared to a lead acid battery may be the deciding factor for the present time period… ---

> [@George\_San\_Jose1](#): > > but wondering about the physics. Any theories for why? I am going to back pedal on my statement on the performance of LiFePO 4 batteries when it is cold… Seems there a lot of AI responses to various Google queries with too much mixed information from the various web sites and there are a lot of contradictions… The only thing that seems to remain consistent is that LiFePO 4 batteries do not charge too well when it is cold and should not be fast charged when below freezing. I live in southeastern Virginia and my vehicles are garaged so I do not have to debate the pros and cons too much… ---

LFP batteries are Li-ion batteries. FePO4 is an ion. Check paragraph 4 of the link to see some of the battery chemistries in the Li-ion family. > **[Lithium-ion battery](https://en.wikipedia.org/wiki/Lithium-ion_battery)** > > A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introducti...
