Can I charge lithium batteries in the cold?

Lithium batteries rely on chemical reactions to work, and the cold can slow and even 
stop those reactions from occurring. Unfortunately, charging them in low tempera-
tures is not as effective as doing so under normal weather conditions because the 
ions that provide the charge do not move properly in cold weather.

There's one hard and fast rule: to prevent irreversible damage to the battery, don't 
charge them when the temperature falls below freezing (0°C or 32°F) without reduc-
ing the charge current. Because the lithium batteries suffer from a phenomenon of 
lithium metal plating on the anode if charged at high rates in cold temperatures. This 
could cause an internal short of the battery and a failure.

Can I leave ECO-WORTHY lithium battery on charging all the time?

For a lithium battery with a low maintenance charging procedure and battery 
management system, it's perfectly fine and better than leaving them discharged for 
a long period. Regardless of whether it is a dedicated charger or a general charger, 
under normal conditions, it has a charging cut-off voltage, which means that it will 
stop charging at a certain volt. The same is true for the solar panel controller, and the 
controller can also be configured like this. The solar panel is directly connected for 
charging. If there is a problem with the BMS, it may be overcharged.
