LED Battery Charge Cable

Friends with Excalibers have asked about a LED cable that would indicate when and if the batteries are fully charged.
(I once had an Excalibur, but had to give it up.....)
They got all the way to the beach, and the batteries were flat. Seems to happen somewhat often to them.
They thought it was charging, but maybe the connections were bad.
They are off on vacation now, so I can't look at their detectors.
I have found a cable that can be re-designed to do this.
The LED actually measures the current flowing to the batteries.

The LED is part of the cable and shows:
Red - very low battery - charging.
Amber - charging
Green - Fully Charged
Can be seen far away to keep an eye on the detector without turning it on.

Is there much interest for this sort of thing?
It would be in between the charger output and the detector input.
No modification of the detector or charger would be necessary.
Voltage around 12V max.
Useful for other detectors?
If so, need the size and type of input and output connections for the Excalibur and other detectors.

Any input on this project would be greatly appreciated......
 
How big is the setup....

I would be interested in one to install inside of the pod so before your hunt or during you can check it, you would have to keep the battery disconnected.

Also before every hunt I check the battery with a voltmeter specially if I don't charge the machine, but it would be nice to just connect the battery and see if the color is a go....
 
Hi,
How about a unit like this ??
http://www.ebay.com/itm/Li-Po-Battery-Voltage-Indicator-Checker-Tester-2s-6s-BC003-/301095393595?pt=Radio_Control_Parts_Accessories&hash=item461aaf193b
It is actually intended to be used on the balance plug of LiPo batteries but it indicates correct voltage precisely down to 1/100 of a volt.
If your excalibur has a clear battery compartment you can clearly see the red digital numbers from the outside.
The unit shown is for up to 6S packs but you can also get units half the size intended for 3S packs
Just a thought

Here is a picture of the LED Battery Charge Cable. This would have to be modified for each type of detector....
 
Don't think that would work for me, I need a single LED that I can solder to the PCB with limited amount of space, one that voltage could be from 16 volts to 10 and would change colors as the voltage drops. Maybe they have something like that?
