Basically a traveling...configurable
powerplant:
It can recharge all smaller batteries and
provide A.C. for other appliances....i use
it to power a bug zapper and a
recirculating micro-sluice.

Metal detector: battery modification.
Most metal detectors run off two tiny 9vdc batteries.
This gives you about 20 minutes of usable life in the field.
I added this 18 vdc power tool battery.
It has about 4 hours total use between charges....
and recharges in an hour ( in the solar case).
If you add it to yours...you better know some basic electronics.
The 2 9vdc are added in series for 18 vdc....
but you have to take it across a resistor network from the 18 vdc
because the detector wants to see the proper current (as if there
were 2 9vdc batteries there).
