The First Plug N Play Addon Board for the SW-COMPUTER


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.

Cool, have we got an estimated cost?

but I'll help you, this time...

$35.00 for the LiPO PCB

Trigger mod (lets you use the PCB with "any" mosfet trigger other than the SW-COMPUTER) is an additional $5.00 per board. Not a difficult mod, but it is time consuming.

I accept paypal for credit cards, more info on my website and the order form (save the order form to your computer then you can fill it out and save it).

UPDATED to reflect current product line

[Double Tap]

Is there anyway to view maybe a collective of images that demonstrate the complete wiring requirements to the SW-COMPUTER and the balance tap on the Lipo pack itself?  I would like to actually see one installed and images taken.  Just a request if at all possible.

sure I'll show mine, but i use my own version of the sw computer board, the exact plugin to the sw-computer is shown on the lipo pcb webpage

gimme a day or so for that, lots to do here

UPDATE:

As it stands, the board is now VERY smart, you can observe LED codes to see what it thinks the pack is as well as GOOD, Weak, and DEAD state.

All PCBs are in stock and in full production, refer to my website for more details
