Very Cool Crumbles, I like!!
Excalibur first with 14.8 Volts 1300 mA 4c LiPo
Then the 1600mA NIMH BATTERY Onlybatterypack 12 V (Green)
Then the stock Minelab Battery 11.5 V
Then with Shauns AfterBurner coil AMP
Each I will measure at full and then 9.5
I like the way you think!
You should sell OBN tricked out Excals. With skullies, amp, straight shaft with pinpoint button on handle, and improved battery. I bet people would be lining up for them.
