I hope this is the correct place for this!

Is there any Excalibur users who converted their machines to 3a or 4s LiPo battery source from the old NiMh/NiCad? Which is the most acceptable approuch 3s or 4s - 11.1V or 14.8V?
Thanks for any input.

Hi Heinrich. There are not many of us who have Excal machines, so I am not too sure how much feedback you might get. I can maybe recommend joining up at http://metaldetectingforum.com/. There are several Excal users there who do extensive modifications. You might get more useful info there.

I am not trying to chase you away, I am just trying to help . Stick around here and post some of your finds.

There is also a thread where you can introduce yourself and show your face

Hi there

Nice thought use lipo batteries, BUT beware of getting them wet, the instant discharge current can be extremely high for a few milliseconds. the end result a an explosion or a melt down within the battery housing. lipo batter have there advantages, they are light and limit the weight that one must carry they also last longer at a higher current drain.
Just some news on LIPO batteries, No air carrier fleet will fly any lipo batteries due to the possibility of a short circuit and a fire, they must be sent from overseas by boat. Two small batteries can deliver 200 amps in a few milli seconds resulting in flames. So beware of them in you value your detectors, even carrying spare batteries in your kit bag can be dangerous. they must be individually wrapped or sealed from each other.
FOOD for thought

Did not know that!
Thanks Dennis

I have seen some YouTube videos of these batteries exploding and melting. It is pretty scary
