Rechargeable Polymer Lithium Battery for Sena 50S Bluetooth Headset

Product Description The DC 3.7V Model Table of Square Rechargeable Polymer Lithium Battery is designed for use in 3.7V-5V electronic products. Before use, please carefully compare the polarity of the connector - the red wire is positive "+" and the black wire is negative "-". The yellow (white) lead serves as a 'thermistor', so do not reverse-charge or reverse-connect.

The 3-wire batteries include red and black wires and can be used to replace 2-wire batteries. If the primary battery of some products lacks a plug or has a mismatched plug or polarity, there is no need to worry. You can either cut and solder the plug directly or use our heat shrinkable insulating sleeve to connect wires of the same color.
