I second the Tenergy batteries. Had a set of them & the supplied Powerizers for over 12months. I alternated between them & both sets were still giving more than a full days detecting when I recently sold the SDC.

If you threw the Powerizers away due to the shutdown issue some coil tape would have fixed that. The Tenergy batteries are a lot better in that regard due to a larger lug giving more contact if that makes sense, I never had the shutdown problem with them but others have reported it happening with them & some tape stopped it to.

Glad you got it sorted out Paul. However, for others who are reading this thread there was an extensive discussion of the SDC 2300 charger and battery options shortly after the SDC came out here on the forum

Another vote for Tenergy batteries. I got the eight pack of the regular blue 5000 mAh version as I never could figure out what the difference was between them and the "Premium" 5000 mAh version. The eight pack was slightly less per battery and gave me a backup set.

      A week or so ago I had ordered a 3D printed battery pack for whites machines, obviously including my V3i. It uses 3 of the large lithium rechargeable 18650 batteries. I received it already even though it was shipped from Ukraine. It has a rugged, premium feel to it. This is my first 3D printed anything, and the quality surprised me. Definitely not a flimsy piece of kit. It fits in my V3i perfectly. Right now I’m using 2,500 to 3,000. I’ll let you know how these hold up and how higher MAH versions hold up once they arrive. I’m pretty excited about these in comparison to competing packs that top out at 3100 mah. It’s an inconvenience to not be able to charge the pack itself without removing the batteries, but an open holder also has its advantages. I may even attempt to make a charging cradle. The pack seems to only be available on eBay, with one remaining at this moment. I’m sure he will fire up the printer for another batch soon though. He likes to sell one batch before making more.

      Saw this on Ebay.  I had wondered if these expired battery packs could be converted.  There is also a NiMH version (orange label).  I don't know if that can be converted or not, but this person figured out how to do so with the NiCad version.

      Can anyone shed some light on the batteries that minelab detectors use?
       
      1. Longevity
      2. Cost to replace
      3. Estimate if those particular batteries may go obsolete (as opposed to AA batteries)

      I am attempting to purchase a White's battery holder, P/N 802-7150. Canadian Treasure Seekers has one in stock, but due to supplier contracts can not ship to US.
      I hope to find a fellow hunter from Canada that is willing to purchase and send this battery tray to me. I will, of course, reimburse any cost for item and associated shipping costs.

      I bought a house in meadview about 4 years ago.  Every couple months when I go there I try to get over to gold basin to do some detecting or drywashing.  It took me a couple years to find my first nugget out there and its been a couple of years since then and I havent found another.  I swing an SDC and I've read people have done pretty good out there with that model.  I find plenty of lead and boot tacks a inch or two down but not much deeper than that.   What settings are people using out there?  How deep down are people finding the gold?  Would I be better off with a  different model that can go deeper?  I'm not very confident in my abilities since I learned this machine on my own and have only found 2 pieces in the 4 years and dozens of times I've used it.  Any advice would be appreciated.

      I opened up my TDIBH the other day for some fiddling around and checking out a few things. I powered up the detector with all of the guts and board opened up and had it hooked up to the 14.8v (4 x 18650 cells) battery pack. I had it going for just a few minutes when I gripped the circuit board as part of my “fiddling” around......well I dropped the board and swore a bit in response the burn I was expecting on my fingers. Well it turns out that on the opposite side of the board behind where the big capacitors sit is some sort of heat sink and I can tell you the heat from this spot was something else. The detector has and runs just perfect but the hotspot really surprised me. 
      I decided to hook up the 12v battery pack and let it run for a decent amount of time and it never got past a mild warm on the back of the board. That extra couple of volts is generating some serious extra heat.....bit like on the heat sink area of the CPU chip in your computer.
      I honestly don’t know if the detector can handle this extra heat long term but I’m not taking any chances. I’ve moved back to the 3 x 18650 battery pack which I knocked up when I first got the detector. There is a slight loss in depth but surprisingly not too much. I feel the performance of the 11.1v Lithium setup is maybe 1 to 2 inches behind the 14.8v “hot pack”.
      You can see in the photos the big caps on the detector and where the heat comes from. The other photo is my 11.1v pack which packs some punch and lasts much longer then the stock NiMH pack.
