JPS Posted January 20, 2023 Share Posted January 20, 2023 hello to all, I'm new to the site, I saw that on the tdi pro you could increase the voltage up to 21 volts and on the surfmaster how much can you increase the voltage, it's a box of 8 batteries for 12 volt. what is the difference in power between the surfmaster and the tdi pro oz and why, is it not the same components, thank you for your answer Link to comment Share on other sites More sharing options...

I did extensive testing and field use with my TDI BeachHunter…..there’s plenty archived for you to read about this subject. Essentially, I achieved between 10% and 15% depth increase moving from the 12v pack to 14.6v. Not much of a real gain. The heat increase on the PCB was unbelievable….I opened the case to check things out and one part of the board left a small red mark when I put my finger on it for just a second or two…..that’s hot. Amps to the coil has a far bigger result than voltage when it comes to coil “depth”. A capacitor may be able to handle the extra voltage but I can assure you that not all parts on the PCB will enjoy the extra heat. Maybe you can add a heat sink? Stick with the stock battery and let Mother Nature take off the extra 10% to 15% of sand. An example of volts v Amps is my GP3500 which I use at the beach. Now it’s only running on a measly 6v battery but it’s drawing about 0.75A from that battery…..that’s where the power is. Link to comment Share on other sites More sharing options...
JPS Posted January 21, 2023 Share Posted January 21, 2023 thank you tony, but as I saw that many people increased their white's up to 18 or even 21 volts I inquire, I don't know anything about the pi. 16 volt i think is a good deal? hello to all, I'm new to the site, I saw that on the tdi pro you could increase the voltage up to 21 volts and on the surfmaster how much can you increase the voltage, it's a box of 8 batteries for 12 volt. what is the difference in power between the surfmaster and the tdi pro oz and why, is it not the same components, thank you for your answer Link to comment Share on other sites More sharing options...

Dustin M Posted October 18, 2023 Share Posted October 18, 2023 I have the original White's TDI with charger and [2] stock 14.4 Volt 4.4 Ah Li-ion battery packs. I haven't used it much since I purchased it new from a dealer in North Georgia many moons ago. Today I went to charge one of the packs and I noticed the charger getting a little warm. Is that normal?

Geotech Posted October 19, 2023 Share Posted October 19, 2023 Yes, the charger normally gets warm, and if the battery is especially low the charger will get especially warm. For a battery that has been on the shelf for a year or more, I would closely monitor the charger to make sure it doesn't overheat. 4 Link to comment Share on other sites More sharing options...
Joe Beechnut OBN Posted January 31 Share Posted January 31 Asked by a friend to make him a couple batteries for his, New to him TDI Pro, seems fairly easy so I order the parts. I did not feel comfortable about making him a 5 cell 18/21 volt Li-ion so we agreed on the 16.8. 4 cell.. For now... WIll post pictures. Parts came in today.. make this a thursday project. 1 1 Link to comment Share on other sites More sharing options...
