This PCB (Protection Circuit Board ) is designed for 3.7V Li-ion
and Li-polymer battery pack
Supply 3.7V Li-ion or Li-polymer battery to 5V Output.
Fully Compatible with both Li-Ion and Li-Polymer cells
designed for: 16340 17500 17650 18500 18650 or any other 3.7V battery.
Dimension: 40 x 10 mm
Li-Ion and Li-polymer Battery packs must have a protection circuit module to keep
Li-Ion/Polymer Battery from over charge,
over discharge, and to prevent accidental battery
explosion due to its extra high energy density.
This protection circuit is specially designed for 3.7V Li-Ion Battery packs
made of Li-ion and Li-Polymer cells.
