Image shown is of LiPO PCB prior to configuration and enclosure in heatshrink. This is done to allow for image clarity.
An example of a factory configured 2 Cell PCB ready for shipping is at the bottom of the page.

Specifications:

Size = 2.70 x 0.65 x 0.17 inches (68.6 x 16.5 x 4.35 mm) (L x W x H)
Operating Range = 2, 3, and 4 Cell LiPO Packs (7.4, 11.1, 14.8 VDC Nominal)
Operating Power Consumption = Less than 30 milliamps (mA)

How It Works :

The PCB monitors each LiPO cell individually, specifically looking at the steady state voltage of each cell.
When any cell voltage drops below 3.2V 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 single cell voltage of less than 3.0V.
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.
Since this Warning Level is set at 3.0V, the LiPO pack will always be able to be recharged.

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

TRIGGER MOD MUST BE NOTED ON ORDER FORM

Features:

1. Per Cell Voltage Monitoring, Ensures that no single cell will overdischarge below acceptable charging limits.
2. Design optimized for "Plug N Play" operation with Extreme-Fire.com SW-COMPUTER. (Requires software versions 2.7 or higher, contact myself or Gandolf if you need an upgrade or if you are unsure of your sofware version). If you bought your SW-COMPUTER or TRIGGER MASTER after March 2008, it is 2.7+.
3. Ultra low power consumption keeps power where you need it, on the motor.
4. User reconfigurable for different LiPO packs. (Board must be matched to number of cells in the monitored pack.)
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).

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

LiPO PCB Connection Manual - Detailed instructions on how to connect your LiPO to the PCB.

Notes:
1. The PCB requires at least a 2 Cell LiPO pack to function, 1 Cell simply doesn't have enough voltage to run the chips.
2. The PCB functions to prevent Over-Discharge NOT Over-Current draw, the SW-COMPUTER or a Fuse can do this.
3. To prevent over-current draw (and the resulting thermal runaway), use a LiPO Pack that is rated for 20 Amps or greater continuous discharge.
4. 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 conventional (NiCD/NiMH/SLA) cell chemistry packs, failure to comply WILL damage the PCB and VOID ALL WARRANTIES.

If your LiPO Pack does not have balancing taps and you want to use a PCB, contact me for a custom version that will monitor the whole pack, it is available for $35 USD and uses the board for the NiCD/NiMH PCB but with the same high precision components of the LiPO PCB.

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 Balancing Port to the PCB
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 the LiPO Power Tap connection used to monitor cell voltage. Do not leave PCB connected to your pack indefinately!
3. Remove the battery pack from your AEG.

Special Notes:
This product assumes that the buyer is able to disassemble and reassemble the AEG and/or mechbox fairly easily.
Rewiring and soldering may be needed for installation of this product.
