The lithium-ion battery has dramatically more battery-charging cycles compared to a lead-acid battery which makes the product life so much longer. Besides, Lithium-Ion batteries are small and lightweight and fit in many small electronics such as a mobile phone or laptop computer.
The power of electricity that a Lithium-Ion battery produces is powerful which means it requires a charging voltage control at the highest level. Also, Lithium-Ion batteries cost more than lead-Acid batteries because of the material it uses.
SANUPS A11K-Li finished its development and is expected to be released in early 2019.
