PCB for 3.7V of Li-Ion Battery (3.5A+/-1A limit)

Protection Circuit Module Specifications  for 3.7V  Li-ion  Pack with 3.5 A current Limit

All Li-Ion Battery packs must connect to a protection circuit module to protect Li-Ion Battery from overcharge, over discharge  and to prevent accidental battery explosion due to its extra high energy density. The protection circuit is specially designed for 3.7V Li-Ion Battery. It also can be use for Polymer Li-Ion battery sold by Batteryspace.
Please refer to the specification on how to wire the pcb to battery. 
Please be advised that this circuit will provide the following protections:

• Prevents 3.7V  Li-Ion Battery pack from overcharging 4.35V
• Prevents 3.7V  Li-Ion Battery pack from over discharging 2.4V
• Maintains 3.7V Li-Ion Battery pack's discharge current lower than 3.5A.
• Protect battery from short circuit and wrong polarity
