Tony Posted February 12, 2019 Author Share Posted February 12, 2019 All of the part details and assembly is at the beginning of this thread. The brass terminals are from the electrical section of most hardware stores and the wire and 2.1mm DC "Barrel" connector from electronic stores. I am in Australia but the parts needed should be readily available just about anywhere. Very simple build and soldering. Tony 1 Link to comment Share on other sites More sharing options...

Had a few hours off work today and thought more about this 16.8v project. ---- (Having experienced the CTX3030 LIION battery bay leaking (on that machine I only use the AA NIMH 1.2v tray when detecting in fairly deep water). NIMH has less current in the event of a salt water leak). I have not had this machine submerged yet, so unsure if to trust the housing! -----; I wanted to be able to use the stock NIMH pack in the TDI BH and also the LI ION 16.8v pack for the beach when extra depth is needed! In the end I decided to undo the previous method with the screws on the battery terminal. I wanted a "stock" 16.8v battery tray! Given the NIMH tray is only about 13USD on Amazon I decided to sacrifice the NIMH tray that came with the detector! A) remove lid B) remove all metal connectors C) Dremel the chassis empty. You need to take away some of the thickness of the bottom of the tray, otherwise you won't be able to get the LI ION cells into the detector. You will need a thinner lid also! Be careful not to damage the exterior of the tray. D) as this was a trial, I used some old 18650 cells, a 4s balance lead, and a deans plug. (Final version will have. Built in balance board, and charge connector so the lid won't need to be opened for charging) D1). Three cells side by side. One on a 45 degree angle. Fits fine! E) wired in series for 16.8v. hot glued into original battery chassis. The result - a LI ION pack that I can "change out"with the standard pack! Trial completed. The next one will be more tidy!! ****After 3 hours of detecting, still above 14v**** Good job Dale.....this is the way to go if you wish to use the standard battery trays and your DIY extra voltage packs. I like to run max power all the time (in the water and on the beach).....I got a second 16.8v pack and will swap out after 6 hours but by then I am pretty much done ! 1 Link to comment Share on other sites More sharing options...

Surely you can by Lithium 18650 cells in Canada ?......correct, they can't be shipped by air from overseas. 1 Link to comment Share on other sites More sharing options...

Posted files a while ago. If I remember well, it was just an adaptor you have to drop in the housing to touch battery leads, so no need to hook up wires with nuts and bolts... In other words, this will fit to any pack you are planning for the TDI. You have just to add the battery pack.... Link to comment Share on other sites More sharing options...
PASTASHELL Posted August 18, 2019 Share Posted August 18, 2019 I do want to do this but I am frightening of frying the damn thing :( Link to comment Share on other sites More sharing options...
Timmysys Posted September 8, 2019 Share Posted September 8, 2019 Great topic! What do you think guys, the Dual Filed work with 14,8V Lithium-ion battery pack? If the circuit tolerate, give some depth gain? Link to comment Share on other sites More sharing options...
