sd 2100 sd2200 voltage

Hi i have a 7.3 volt 7500ma lithium batterie i wish to use on my detectors 2100 and 2200.

The
issue i have is that when it is charged it puts out 8.4 volts , will
this fry my detectors or will i have to decrease it some how?

If i have to regulate it what is the best way to do it because most regulators rob 2 volts just to operate.

Thanks

No idea how to regulate it. I don't think +8 volts will do it any good. I run my 2200 at 7.3V - seems to be the sweet spot

Hi Zacc

Check under Other Minelab Info - there is a comment on regulating a battery there

Hi ZAC.


Considering your lithium battery does charge to 8.43vmax,it can not be used directly on your sd 2100 and 2200 without consequences.But you can safely run both machines on 7.9volts and bellow without damage,to the electronics of the machines.You will also have to change to an inline enhancer that is made for a GPX 4000 But 4 pin not 5 pin so as to suit the SD series machines,for the older version of enhancers,which were made to handle the SD series machines will cut out at 7.4 volts.Solution,Independent battery model which clips on to your belt,such as a Neptune model,battery operated enhancer. Now since you only have one 7500mA/h,by charging it to 7.9 volts and not full capacity,you'll be lucky to get 5 hours use before the battery cuts out;[cut out point at around7.5v]unless you get another similar sized battery,and run them in parallel,giving you at least 10hrs detecting time before recharging.By using this above mentioned method,always make sure that your voltage,reads 7.9 volts on a volt meter,before plugging it into your machines.This above method does not require a voltage regulator.It is run directly off your battery into the machine.
