The onset and intensification of lithium-ion battery fires can be traced to multiple causes, including user behaviour such as improper charging or physical damage.
There is less capacity for power storage in the battery when the temperatures are cold. You should never charge a lithium battery when the temperatures are below 32°F as it can cause the lithium ions to bind into lithium metal and short the battery internally. Lithium-ion batteries heat up when you are charging them at very high rates.
Overheating protection circuits also prevent the battery from getting too hot while running or charging. 4. Charging in a Hot Environment. Lithium-ion batteries are notably heat averse. While being too cold can reduce the battery''s power capabilities, getting too hot can completely destroy it.
A lithium-ion battery is comprised a positive electrode called a cathode, and a negative electrode called an anode. The third central part of a lithium-ion battery is the electrolyte, a chemical layer between the cathode and anode. In many applications, the battery''s cathode is comprised of lithium cobalt oxide and the anode is made of graphite.

Lithium-ion batteries have a high energy density. They store a lot of energy in a small body full of flammable components. When a cell is damaged, it leads to a sudden rise in pressure and temperature that releases flammable gases. It begins a chain reaction that instantly takes out all the other cells in the battery pack too.
Anything over 200 F would be worrying, 250 would be burn out territory. And FWiW an alternator rated for 200 amps will burn out if run at 200 amps for long. 200 is just the maximum and shouldn''t be used for long. Kind of like engine rpms. A DC to DC charger is probably the best solution.
Due to lithium-ion batteries generating their own oxygen during thermal runaway, it is worth noting that lithium-ion battery fires or a burning lithium ion battery can be very difficult to control. For this reason, it is worth understanding how lithium-ion fires can be controlled should a fire scenario happen.
