Here is the problem with buying a Chinese HydroFoam off ebay.

I am now thinking I would like to have 2 batteries for it, but of course I have no support for my ebay hydro.

I look through the manual and it says it has a “High-Octane Batteries”.

That does not help me much,  who knows if it is even the right battery for my engine or not.

I found a neat little batter temperature gauge that you can tape on the side of the battery and it will tell you the temperature.

I am thinking about getting one of those, or some kind of device that will tell me the temperature of the battery and the engine (since that is important also).

Anyway, I think those cost around $50 and the little stick on gauge was around $4.

I guess I can take a picture of the battery and then start posting it on the different forums and see if I can find anyone who recognizes it and can let me know what it is.  So I can try and find another one to buy.
