For the rechargeable (generally refers to the lithium battery) from the protection of the integrated circuit board. Lithium battery (rechargeable type) so need protection. As the lithium battery itself determines the material itself can not be overcharge, over discharge, overcurrent, short circuit and ultra-high temperature charge and discharge, so lithium battery lithium components will always a protective resistor with a sampling resistor and a current fuse. colour:green Material:PC + Metal Size: .50*30*2mm Package Contents: 1 * 6S 15A Lithium protection board Only the above package content, other are not included. Note: Light and different displays may cause the color of the item in the a little different from the real . The measurement allowed error is +/- 1-3cm.
