Protection Circuit Module Specifications for 3.7V Li-ion 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 3.7V Li-Ion and polymer Li-Ion Battery.
Please connect battery pack with the circuit as the following drawing with wire provided.
Please be advised that this circuit will provide the following protections:
* Keep 3.7V Li-Ion Battery pack from overcharge beyond 4.35V
* Keep 3.7V Li-Ion Battery pack from over-discharge below 2.4V
* Keep 3.7V Li-Ion Battery pack 's discharging current > 8.5A
Batteryspace is not responsible for any damage caused by misunderstanding and misuse! Please read the specification carefully before assembling it to battery pack.
