PCM with Equilibrium function for 51.8V Li-Ion Battery Pack at 40A limit

Protection Circuit Module for 14 Cells (51.8V) Pack

This protection circuit is specially designed for 51.8 V Li-Ion / polymer Li-Ion Battery pack with 40 A discharging rate. Different than normal PCB, it provides equilibrium function after battery pack is fully charged. PCM will detect each cell's voltage and trim higher voltage down until other cells reach the same voltage level. Therefore, it helps Li-Ion cells have longer service life. Also the PCM will provide the following protections:

Prevent 51.8V Li-Ion Battery pack from over charge
Balance each cell at Max. 4.325/cell (required voltage tolerance within 0.2V for each cell)
Protect 51.8V Li-Ion Battery pack from over discharge ( 2.50V/cell)
Limit 51.8V Li-Ion Battery pack's discharging current below 40 A.

Features:

Apply for 14 Cells Li-ion / Li-polymer Battery Pack with discharging current < 40A
Internally Trimmed Voltage Limits to balance each cell. Please wait 30 minutes for equilibrium function to take place after charger indicated battery pack is fully charged.
40A discharge current limit detection
Dimension LxWxH :150mm (5.9") x 140mm (5.5") x 9mm (0.3")

Tip:

You may order our 12AWG wires to handle 40A current draw from our website. Please see our wire chart for recommend AWG for current draw.

To monitor the voltage level of the battery pack from the PCM, you need to order a fuel gauge display here

For 51.8V PCM without fuel gauge socket, please DIY with correct polarity

Red wire to P+ spot of PCB
Black wire to P- spot of PCB

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. When charger LED turn Green, allow 30 minutes for pack to balance before use
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.
