[QUOTE="karelian65, post: 578430, member: 9224"] Tested three standard factory battery packs, all charged a couple months ago. All three were close to 16.5 volts. Fully charged the 5 cell pack should come in just over 20 volts. Looking back to the Tdi SL there was a small but noticeable improvement in depth and performance going from 3 x 18650 to 4 x 18650. With the Tdi Sl there was the knowledge that the machine was running at its best for hours. So will there be the same improvements with the Pro? Early Reidman battery users in the US indicated that there was an improvement. I'm in Melbourne, so an air test is the best I can do for the moment. Reg the Tdi Guru (RIP) made the point that higher voltages lend themselves to using either White's or Miner John coils, something to do the the resistance on Minelab compatible coils.. So tests will be with the White's and Miner John coils I have. More soon. [/QUOTE]
