LiPo on the Excalibur

[OldBeechnut]

Thanks to snookson who did this over a year ago and I'm finally getting my hands dirty. He claimed more depth and a much longer run time, Early testing I can tell there is a bigger tranmit field from the coil. I know there are a lot more Volts going into the board ( 16.8 ), testing and seems like all is fine after 40+ hours of run time on the bench, no more heat on the board then the stock battery (13.7). Field time starting next week....till the end of Sept...

So far in the coil change endcap 14 hours of underwater time, no issues other then a bad S-5 coil...

Hi,

I also use lipo on my machines
PI and VLF
a lipo 22.2 volts (25 at full load)
with a control card that pulls the desired voltage

gives considerable autonomy
always being at full power

Hi,
Could you please post a link (manufacturer and model) to the above mentioned control card ??
I run LiPo on my 6000Di Pro SL and while the detector handles the increased voltage without any probs, It severely pegs out the meter if I accidentaly switch to battery check which is just one click past hot rock reject.
Thanks in advance

Hi,

I used a card converter constant voltage, like this
different model on ebay

the important thing is to have an output voltage between 12 and 18 volts
which will be enough for 99% of detectors

@ LE JAG,
Thanks for the link.
Ordered me a couple

Nice work LE ...SP post me a few pics, I need idea's...do you have to pull yours to charge...seems to be no way around it.....like to seal it up good and go from there....what kind of LIpo you using, and what kind of hours between charges....also have you noticed any extra depth.....seems to be a large transmit field but have yet to test on the beach....thanks joe

for the charger, I use an Imax B6

https://www.hobbyking.com/hobbyking/store/__6478__IMAX_B6_AC_Charger_Discharger_1_6_Cells_GENUINE_.html

it can just load, both the as NiMH lipos, and other ...

I should have added a 12 pin on the case to allow load balancing mode, without having to open it ..

and interuptor, control board consumes less energy when it is connected

- I do, 12 hours (without problem) with Goldscan on 18.5 volts
and it consumes far more than any other detectors !

yes, there is a gain in depth
with PI, the impulse is not limited to the PI
stronger it is, the longer magnetized sand depth ...

I do not think the gain will also be high on a BBS ?
but with such a battery, you will be the maximum performance for several days : )

Hey OBN, How is your experience with the new LIPO mod? Do you notice more depth?
