FAQ

How long does it take to charge a smart battery 12v 300ah lithium ion battery

Just same like most of other rechargeable batteries. a 12v Lithium ion battery charging voltage is 12.6v if NCM cells inside. While if the battery form by LiFePo4, then it is 4 in series. Charging voltage is 14.6 volt. Charging time all depending on the Charger output current. For example, if we use a 12v 100A charger. Means we can fully charge the 12v 300 amp hours by 3 hours. If use a 12v 50A charger. we can fully charge it by 6 hours.
