Protection Circuit Module (PCM) with Equilibrium Function for 25.9V Battery Pack at 25A limit

MODEL # PCM-L07S30-064 Protection Circuit Module for 7 Cells (25.9V) Li-Ion Pack with 25A Limit

This protection circuit is specially designed for 25.9V Li-Ion / polymer Li-Ion Battery pack with 25A discharging rate.  Different with normal PCB, it provides equilibrium function during charging, e.g. PCM will detect each cell's voltage and trim higher voltage until other cell's voltage reach same, therefore allow Li-ion cell has longer service life. Also the PCM  will provide the following protections:

• Keep 25.9V  Li-Ion Battery pack from overcharge ( 4.2V/cell)
• Balance each cell at Max. 4.25/cell ( required voltage tolerance within 0.2V for each cell)
• Keep 25.9V  Li-Ion Battery pack from over-discharge ( 2.75V/cell)
• Limit 25.9V  Li-Ion Battery pack's discharging current below 25 A.

Features:  

• Apply for 7 Cells  Li-ion / Li-polymer Battery Pack with discharging current  < 25A
• Internally Trimmed Charge and Discharge Voltage Limits to balance each cell
• 40A Discharge Current Limit Detection
• Dimension (LxWxH):  5.5"(140mm) x 2.2"(55 mm)x 7.7mm(0.3")

Warning:

• If you want to use this pcm for a battery that is rated less than 25A drain, you must add additional protection device to protect the battery itself. Such as: proper rated polyswitch.  
• To achieve balance, each cell in battery pack must has equal voltage within tolerance of 0.2V.
• You must be professional in Li-Ion battery pack to buy the PCM. Misusing PCM may cause battery damage or explode.  We are not responsible for any damage caused by user.

Batteryspace is not responsible for any damage cause by misunderstanding and misuse! Please read the following instruction carefully before assembling.
