PCM with Equilibrium Function for 25.9V Battery Pack at 40A limit

MODEL # PCM-L07S30-073 Protection Circuit Module for 7 Cells (25.9V) Li-Ion Pack with 45A Limit

This protection circuit is specially designed for 25.9V Li-Ion / polymer Li-Ion Battery pack with 40A discharging rate. Different with normal PCB, it provides equilibrium function after fully charged, 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 40 A.

Features:

Apply for 7 Cells Li-ion / Li-polymer Battery Pack with discharging current < 40A
Internally Trimmed Voltage Limits to balance each cell. Please wait 30 minutes for this equilibrium function to take place after charger indicated battery pack is fully charged.
40A Discharge Current Limit Detection
Dimension (LxWxH): 5.7"(145mm) x 2.4"(60mm)x 7.7mm(0.3")

Please connect battery pack with the circuit as specs Please download the specification.

Warning:

If you want to use this pcm for a battery that is rated less than 40A 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.
