14.8V 5Ah Professional Rechargeable Lithium Battery Pack For Portable Medical Device power tool
Lithium-ion polymer batteries: use polymers to gelate liquid
organic solvents, or use solid electrolytes directly. Lithium ion
batteries generally have graphite carbon as the negative electrode.
According to the electrolyte materials used in lithium-ion
batteries, lithium-ion batteries are divided into Liquified
lithium-ion Battery and Polymer lithium-ion Battery , deep cycle
high discharge battery pack.
Installed polyswitch will cut off power if battery discharge current more than 6.6Ah.
14.8V 5Ah rechargeable li ion battery pack with SMBUS data communication and LCD display.
