Description

Protection Circuit Module (PCB)

Li-Ion and Li-Poly battery packs should always use a protection circuit to prevent the cell from overcharging or over-discharging. The Tenergy 32002 protection circuit module is designed for use within a single-cell battery pack and has a working current of 3.5A with a cut-off at 6A. The round circuit fits nicely on the bottom of your Li-Ion or Li-Poly 3.6/3.7V 18650 cell for a neat, streamlined battery pack.

Connections
B+ Connect to cell's anode
B- Connect to cell's cathode
P+ Connect to the cell's output or charger's anode
P- Connect to the cell's output or charger's cathode

The idea of this battery protection circuit is great. However, once it goes into a protection mode it does not come back. Item 7 in the users manual for this device seems to indicate this hangup but it occurs not only on first time use as it claims but after going into protection mode also.
