Protection Circuit Module Specifications for 10 Cells 18650 Li-ion Battery Pack

All Li-Ion Battery packs must connect to a protection circuit module to protect Li-Ion Battery from over charge, over discharge and prevent accidental battery explosion due to its extra high energy density. This protection circuit is specially designed for 37 V Li-Ion Battery pack made of 10 Li-ion cells. It can also be use for Polymer Li-Ion battery sold by Batteryspace.
Please connect individual battery to this according to the wiring diagram shown.
Please be advised that this circuit will provide the following protections:

• Keep 37V Li-Ion Battery pack from overcharge
• Keep 37V Li-Ion Battery pack from overdischarge
• Keep 37V Li-Ion Battery pack 's discharging current lower than 27 A

Apply for
