    Like to see a picture of your work and details on the batteries used? I just made a battery pack for my heated gloves using the Samsung 3.7 volts 2600 mAh 18650 Li-ion. Gloves are 7.4 volt..

    I'm guessing but you must be MAx charging the battery's to get that many volts from 4.

    Added depth is great...... but a lot of times if the sand has everything buried gold just isnt there unless something moves. Winter months can be good hunting...... longer tide swings, deeper tides pulling targets off the beach more than in the summer, at really low tides you can get more long shore drift and bigger waves from the lower water hitting the sand bars/slopes in the water...... and of course the wind as we get more strength from the jet stream. Watch the movement ...... then bring out those PIs.

    Battery case used above is a modified AA cell battery case included with the TDI BH.


    Keeppower protected 18650 Li-ion cells were purchased on e-Bay Australia, a charger for these cells are required.

    More details as requested the lid need to be slightly flexible to accommodate and curve over the larger 18650 cells, beyond this it's a simple modification.

    Joe...... in order to get that higher voltage woudnt you first have to change the batteries inside...... then the ones in the Pod have to be the same or they would equalize the voltage much like water will do with a restrictor to the lower voltage? Couple of hundred bucks for that pod mod...... but NOT opening that box would save you down the line id bet in repairs.

    Dew, these are the things I am thinking, and I haven't even got one yet........... external battery if I go the TDI, opening and closing that door is not a good thing over time if you are a "in the water hunter". Plus the batteries would not be limited to the size of the battery box. Being a external battery there are so many more options since the excalibur pod can hold a LiPo. See the TDI is a current driven machine, you hunt 6 hours, the last few hours your not at the top of your game on depth because the voltage is lower. With a external battery you could carry a extra battery and 3 hours into the hunt just change out batteries, the voltage stays at it's best, for deeper targets.......

    Come on Fisher your testing my patients...

    You better figure out what to do with those pods and discontinued Ikelite connectors Joe..... you never know what ML has planned for the Xcal if PIs take off. Let me see..... Joe you get the TDI, ill get the 8000, and Cliff can get the Fisher ..... then we can swap stories lol.
