Tenergy 32002 Protection Circuit Module (PCB) Round for 3.7V Li-Polymer Battery 3.5A Working (6A cut-off)
Item #:
TENERGY-32002-LIPO-PCB-3V7-RND
Brand:
Tenergy
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.
