Protection Circuit Module (PCB) for 7.4V Li-PO & Li-ion 18650 / 18500 Battery Packs (7A Limit)

Features and Benefits

• Protection Circuit Board for 2S Li-ion and Li-polymer battery pack
• Designed for 2S Li-ion or Li-Polymer battery
• Prevents 2S Li-ion or Li-polymer battery from over-charging, over-discharging and from discharging current more than 8A (11A cut-off). 
• Fully Compatible with both Li-ion and Li-Polymer cells
