Battery protection board, as the name suggests battery protection board is mainly rechargeable (Refers to the lithium battery) and protects the integrated circuit board. As the lithium battery, its material determines itself cannot be overcharge, over-discharge, short circuit, ultra-high temperature charge, etc. So lithium battery lithium components will always follow A protective plate with a sampling resistor, and a current fuse. Providing all the above features this 3S BMS board can combine 3 x 18650 battery to form a battery pack to provide up to 15V DC output at 20A current which can be used for heavy applications. Features: Overcharging and Over Discharging Protection Short circuit protection: Yes Applicable assembly: Nominal 4.5V Batteries / 3 strings. Specifications: Model HXYP-3S-BM20 Charging voltage 12.6V – 13.6V Over-Discharge recovery voltage 3± 0.05V Over Discharge Delay Time 150ms Maximum Working Current 20A Maximum Peak Current 30A Length 65mm Width 47mm Height 10mm Weight 12 gm Package Includes: 1 x 3S 20A 18650 Lithium Battery Protection Board. *Product Images are shown for illustrative purposes only and may differ from actual product.
