Protection Circuit Module ( PCB ) For 18.5V Li-Ion Battery Pack (5 Cells With 8A Limit )

Features and Benefits

• Protection Circuit Board for 3.6V Li-ion and Li-polymer battery pack
  
• Designed for 3.6V Li-ion or Li-Polymer battery
  
• Prevent 3.6V Li-ion or Li-polymer battery from over-charging, over-discharging and from discharging current more than 3.5A.
  

Because of the very high energy density, Li-Ion Battery pack must be connected to a protection circuit module to prevent accidental battery explosion caused by over-charging or over-discharging.

Specifications:

Easy Connection:

Li-Ion and Li-polymer Battery packs must have a protection circuit module to keep Li-Ion/Polymer Battery packs from over charge, over discharge and accidental battery explosion due to its extra high energy density. This Protection Circuit Board is specially designed for 29.6V 8 Cells Li-Ion Battery packs made of Li-ion and Li-Polymer cells.
