Introduction Can a 19V laptop power adapter charge a 7.4V lithium battery with a protective plate? It can be charged at 7.4V with at least two single cells connected in series, regardless of the lithium battery.

Can a 19V laptop power adapter charge a 7.4V lithium battery with a protective plate?

It can be loaded. 7.4V requires at least two single batteries connected in series. When lithium batteries are used in series or parallel, they must be equipped with a protection plate. The battery with the plate itself will change the charge. Voltage limitation, if it is a single battery without board, the output voltage of the charger should be limited when charging. The 19V adapter cannot charge a single 3.7V lithium battery without a card.
