Charging The Gpx-6000 In A 1/2 Ton Truck Or A Car/van?

Based on those numbers if the charge rate is only one amp then it will take about 5 hours to fully recharge, even with system losses it will likely be under 6 hours.

But any alternator can make up that power used from your vehicle with just a few minutes run time, so vehicle battery drain is no real concern if using the DC charger, if using the AC charger it will it cause more battery drain just because of the AC to DC efficiency losses, but still no big deal. Be Aware - Many things take more power than recharging detector batteries, it all adds up.

If your lighter socket goes off with the key I would just hook it direct to full time power wiring or directly to the battery, in either case I would put in an inline fuse rated at about 5 amps in case of a short.

…and running a 100w solar charger all day will replenish the loss of charging a couple 6k batteries on your truck battery.

Gerry, how are you going to change things when you get that Tesla truck? or other electric car/van/truck.

They rent a parking lot here at the beach so that people can sit around before they drive home on weekends and get a charge from the giant batteries on trailers.  That is supposed to be the quick charge and not the 110/220V slow method.

Off-roading and EV’s means a lot of waiting around in the daylight doing a lot of nothing (prospecting?) while the sun does its stuff!

I've decided I am getting a Jackery 1000 with the solar panels. It will be the best method for me to charge my detector batteries. I'll be able to run my ICECO VL60 fridge/freezer 24/7 plus charge three batteries at the same time and never have to pay for power again.

I made this 12v 35Ah (420Wh) portable power battery with left over parts, but you can do it for $100 to $250, depending on options you want, such as solar charging, vehicle charging vs. 120v charging, adding a 120v power inverter, etc.


When fully charged, it runs our refrigerator for a day and could provide about 6-8 charges for GPX-6000 batteries without drawing it down too low.

The battery is based on a low cost 12v 35Ah deep cycle gel cell made for mobility scooters and trolling motors like this:


ML35-12 - 12 Volt 35 AH SLA Battery- Mighty Max Battery Brand Product https://www.amazon.com/dp/B00K8V2VD0/ref=cm_sw_r_cp_api_glt_fabc_5R2WR55KHZYEF1202G21

The Renogy 20amp DC-DC battery charger lets us charge it from solar panels and from our truck batteries- it will automatically charge when the truck is running too:


Renogy 20A DC to DC On-Board Battery Charger Flooded, Gel, AGM, and Lithium Batteries Using Multi-stage Charging


The case is a $9 HF plastic ammo box with a built-in handy cover storage area for cables, connectors, etc. I cut about 1/3 off the side of the tray and used it to mount the switch panel and 12v and USB charging plugs to:



And I added a switch, voltage meter, USB power plugs and a cigarette lighter plug port like this to it:

Linkstyle 4 in 1 Charger Socket... 

Linkstyle 4 in 1 Charger Socket Panel, 12V 4.2A Dual USB Charger Socket Power Outlet & LED Voltmeter & Cigarette Lighter Socket & LED Lighted ON Off Rocker Toggle Switch for Car Marine Boat RV Truck



Also adding a 13.8v step up transformer to run my refrigerator and drone charger as they are designed for slightly higher voltage than the 12v a automotive battery provides after the engine turns off: DC-DC Boost Module 9-12v to 13.8V... 

DC-DC Boost Module 9-14V to 13.8V 10A 138Wmax Power Supply Converter



This project is in progress still (adding fuses and additional plugs) so I can send more info to the build, including how to make just the basic version with the parts listed above and just a few more. Just PM me if interested.

Well I was not expecting to get overwhelmed with so many great ideas and pieces of advice.  It certainly seems we have a trend that more and more folks are trying to live off the grip for short periods of time and then realize the many of the vehicles we have are not suited for such adventures (including my F-150).

There is a wealth of information and tricks/tips provided from you who have actually been out there doing it and figuring a way to make it work.  I appreciate all the feedback and ingenuity.

Some of the things mentioned will take a little time to get done, so this trip I'll be using gator clips, but most certainly will get some of these ideas tried out in the future.  I'll also share this post with the others in the class who are new and not familiar with this fine forum of friends. 

Yes we may get ferocious and snappy at each other on occasion (most of us at one time or another), but the bottom line is.  We all enjoy learning/sharing of nugget detecting adventures and what it takes to have Success.

Who knows,  I might even have Batteries Plus show with their technicians and give a 1/2 day class on best ways to get the most of simple power for all our toys and needs. 

Now that would be the ticket out there at Rye Patch in the summer.  I'll have a ice cream machine, a Slurpee/slushy multi flavor machine, an ice maker, of course expresso, and can't forget the blender to cocktails at the evening social around the campfire.  Boys and our toys...

Thanks again for all the wisdom, ideas, and thought out processes.

By no means am I saying stop posting of ideas and ways you have made it happen.  Heck no, bring on more and keep them coming.

Well said Jerry. This Friday marks the first day of living out of my Tacoma full time traveling back and forth from Montana/Idaho to NV/AZ hunting gold and filming life living Overland style. I no longer have the drive to stay on the rat wheel and paying rent and keeping up with bills that come with a permanent roof over your head. I've always been in situations of wanting to be camped up in the mountains longer and longer periods of time, so now going full time overlanding hunting gold feels like I am coming home to what and where I was always ment to be and doing. All these ideas we all share on here make our stints out hunting gold more enjoyable for all with mobile versions of permanent creature comforts. Let the wandering begin. Reminds me of Robert Service's poem "The Prospector" - From the Tundras of the north to the Mesas of the south....

Grip is probably an appropriate word for it considering the increasing costs of electricity but I think the short term idea is 'living off the grid!"  haha

Gerry, On Amazon, there is a small power inverter, a Bestek 75W DC to 110 volt car inverter. It plugs into the power port and you can plug in the 6000 battery charger into the end. It is a small "fit into you hand inverter".

      This is from Steve’s GPX 6000 accessories page. 
      The following items do not come with the GPX 6000, but are likely to work with it based on what is known so far. This is preliminary guesswork, and it is not advised a purchase be made based solely on the information presented here.

      Shutting it down for this season. During winter I routinely charge up my tector batteries once a week or so for the 6-7 months until spring.  Question.....is this the right thing to do?  What happens to battery life if I don't keep them charged up?  Also curious if I need to keep the wireless ML phones charged regularly and what happens if I don't...???
      Thanks for the input.....

      i have had to use a 3rd party clip clamped onto the coil with a G clamp to charge the coil as the coil cover is out of shape despite it being new and unblemished
      its buckled in the area of the contacts ..both  clips wont contact the terminals so i took off  the coil cover to connect the 3rd party clip with a clamp

      Hi all. I use a GPZ 7000 at the moment. I will be looking at the new 6000 early in the new year. I spoke to a supplier today asking if the mains charger for the 7000 is compatible with battery for the 6000. WAS TOLD NO, as the 7000 mains power transformer supplied is 18 volt not 12 volt.
      Looking at both systems firstly the 7000 series.   Tansformer   input 240 volt- 0.7 amp    output  output 18 volt- 1.67 amp
                                                                                        Goes to BC 10 cradle   input 11-30 volt  23w max   output  8.4 volt- 2 amp AND  5 volt- 0.67 amp
                                                                                        The battery states 7.2 volt  total capacity 72Wh
      Now the GPX 6000                                                 Transformer  input 240 volt- .5 amp Max   output  12 volt- 10 amp
                                                                                       Trans plugs directly into battery   input 12 volt- 1.0 amp?  output 7.2 volt- 42Wh
      What this tells me is Minelab have produced a new detector which uses the same voltage to run as the 7000 but the charging components are not compatible between the models. Should be.
      The new 6000 uses a reduced capacity battery (weight issue?)which  does not last the full day, then you need a spare which you cant charge with mains power until the original is fully charged in about 5/6 hours. After a big day in the field I cant stay awake to swap the batteries so I need another transformer as well?
      I am told by the Dealer though you could use the two car power leads as they are connected to a 12 volt car battery. Cheers sturt

      I had something strange happen, today. I had my GPX 6000 battery fully charged and fresh off the charger.  It had completed its charge cycle and then trickle charged overnight.  I popped it in the detector and started detecting. Within five minutes the battery meter dropped from three bars to two bars.  If I turned off the detector and let it sit for a 5-10 minutes and then turned it back on, it would go back up to three bars for a short period of time before then going back to two bars. Has anyone else noticed this with theirs?
