Re: Lithium batteries: dangers of low temp charging
There are two common types of rechargeable Lithium cell.
Lithium ion, hugely popular from cellphones up to electric cars. Acceptable discharge in cold conditions, but charging may be restricted.
Safe if well manufactured and correctly used, but can explode and catch fire if defective or misused. Cant be connected in series without a battery management circuit, which is often built into the battery.
Lithium IRON phosphate. Somewhat safer under fault or failure conditions.
A 12 volt lithium iron phosphate battery can often replace a 12 volt lead acid battery, the voltage is higher but only very slightly, about 12.5 or 12.6 volts.
The main advantage is much reduced weight, popular applications include motorcycles, especially when ridden competitively, and mobility scooters.
Both types are restricted for air transport.
