Minelab CTX 3030 Aa Battery Pack Will Not Work On GPZ 7000

[gollum]

No need to worry about torching the GPZ. When Steve hit his with 8 1.5v Alkalines (12volts) it would have immediately fried if there wasn't an overvoltage/overamp circuit breaker built in. 

 

Use something like the regulator I posted. Start at 7.4v just to make sure everything works, then creep up the voltage something like .2v at a time until you get to the point that trips the circuit breaker, then back it off, and you know the voltage limit (or you could just call the techs at Minelab and ask if they will tell you). HAHAHA

 

I would be very interested to find out the voltage specifics and the amp draw for the GPZ. With that knowledge, I could easily put together a spare battery or maybe even a super long duration battery for it. Pretty soon, a new battery technology will be taking over this kind of thing. Aluminum Ion Batteries. Each cell is 2volts. A full charge in about 60 seconds. Because of the new chemistry, ZERO chance of fire or explosions as with Lithium Ion or Lithium Polymer. Can't wait.

So, at 72wh and a run time of 8 hours (maximum), That's about an 850-950 milliamp current draw. Any electronics with a 1amp current rating would work, but 3amp would be bullet proof. 

 

That part is easy, but we still need to find the sweet spot where we can input the highest voltage possible without tripping the breaker.
