Image shown is of Conventional (NiCD/NiMH/SLA) PCB prior to configuration and enclosure in heatshrink. This is done to allow for image clarity.
An example of a factory configured Conventional PCB ready for shipping is at the bottom of the page.

Specifications:

Size = 1.85 x 0.70 x 0.17 inches (47.0 x 17.8 x 4.35 mm) (L x W x H)
Operating Range = 7, 8, 9, and 10 Cell Packs (8.4, 9.6, 10.8, and 12.0VDC Nominal) Higher voltages available upon request (16.0VDC Limit)
Operating Power Consumption = Less than 35 milliamps (mA)

How It Works :

The PCB monitors the voltage of the entire pack, specifically looking at a mathematically derived steady state voltage of each cell.
When the calcualted cell voltages drop below 1.125V the SW-COMPUTER is alerted of this via the Caution Line (White Wire off of Pad "C").
This sets the low battery flag inside of the SW-COMPUTER and will cause a low battery error code.
The PCB continues to monitor the cells, looking for a calcualted cell voltage of less than 1.075V.
When this occurs, the SW-COMPUTER is is alerted via the Warning Line (Yellow Wire off of Pad "W"). This triggers the dead battery error code.
If the optional Trigger Mod is used rather than the standard connection to the SW-COMPUTER, the Trigger Mod output will go low.
This prevents the AEG from firing and thus prohibits further discharging of the pack.
The Caution and Warning Levels of 1.125V and 1.075V are factory default and can be changed upon request, refer to the configuration PDF for details.

TRIGGER MOD REQUIRED FOR USE WITH A MOSFET TRIGGER OTHER THAN THE SW-COMPUTER

TRIGGER MOD MUST BE NOTED ON ORDER FORM

Features:

1. Whole Pack Voltage Monitoring.
2. Design optimized for "Plug N Play" operation with Extreme-Fire.com SW-COMPUTER. (Requires software versions 2.6 or higher, contact myself or Gandolf if you need an upgrade or if you are unsure of your sofware version)
3. Ultra low power consumption keeps power where you need it, on the motor.
4. User reconfigurable for different packs. (Board must be matched to number of cells in the monitored pack, failure to comply WILL damage board and VOID WARRANTY.)
5. Low profile design allows for placement in battery bay alongside monitored pack, can also fit in present fuse holder space with MOSFET Trigger such as SW-COMPUTER.
6. All wires and connectors needed are supplied and attached to the printed circuit board where applicable. All wires extend 6" from the end of the PCB.
7. Can be used in conjunction with MOSFET Trigger Circuits other than SW-COMPUTER via Trigger Mod (Additional $5 USD charge, email me if you need this custom modification).
8. Compatible with the Unconventional Airsoft Trigger Master.

Configuration Instruction Manual - Useful for reconfiguring the PCB, PCB's come configured per customer input at time of ordering.

Notes:
1. The PCB requires at least a 7 Cell pack to function.
2. The PCB functions to prevent Over-Discharge NOT Over-Current draw, the SW-COMPUTER or a Fuse can do this.
3. If using a LiPO Pack with any MOSFET Trigger OTHER than a SW-COMPUTER, use a 20A inline fuse to guarantee Over-Current Discharge Protection.
5. If at any time the AEG jams, DO NOT continue to attempt to fire the AEG, this will only cook the FETs, blow fuses, or risk damaging the LiPO Pack.
6. Do not leave the PCB connected to your battery pack when not in use, the PCB constantly draws a small amount of current and can over-discharge your pack if left connected for a long enough period of time.

Not intended for use with LiPO cell chemistry packs, failure to comply WILL damage the PCB, VOID ALL WARRANTIES, and may allow individual cell over-discharge.

Installation and Use: (Detailed PDF here)

1. Connect the PCB to the SW-COMPUTER as shown: (This connection may be made indefinately if you wish to leave the PCB in your AEG when not in use.)

2. Connect the RED Wire from PCB to Battery Positive AFTER the Main Power Connector for the AEG. Or connect to the RED Wire for the trigger from the SW-COMPUTER.
3. Connect the Main Power for the AEG and SW-COMPUTER, the SW-COMPUTER self configures to use the PCB automatically.

After the SW-COMPUTER finishes intializing, the vibration indicating ready to fire will be long, rather than the default short vibration.
Meaning the AEG will behave as follows: Connect Balancing Tap - Connect Main Power - Short Vib. - Delay - Long Vib. - Ready to Fire

To Shutdown your AEG:

1. Disconnect the Main Power connection.
2. Disconnect PCB (If applicable). Do not leave this PCB connected to your pack indefinately!
3. Remove the battery pack from your AEG.
