What are the temps for best performance and life out of GP 3300's. I only Charge at 1 - 3Amps
Temperature not to exced during running the boat. Max temp of cells please???

One thing you will find with these cells, and pretty much any other. Best life and best performance are mutually exclusive.
So, which do you really want? Go real fast, or last real long?

I already go really fast with the cells
Hacker powered tunnel hull
Lasting about 4 mins to the dump the i bring the boat in
I was just wondering what temp the cells should be after a high Amp disharge. Basically i dont want to continue to heat up the cells over what ever temp it is. Would like to get s few years out of the 3300's.
For racing i have to deal with pushing the cell harder, and i understand the - just mucking about is what kills most batteries
I know run time is the cause of the heat so i really dont mind only runing the boat for 3 mins then stoping it. I am not pushing it to hard with the setup also. Just a 8XL swining a 438 prop, surface drive. 80% of the time the hull is not in contact with the water.
For offshore racing I like to see about 135 degrees on the batteries at the START of the race. The temps at the END of the 4 minute race are usually less than when I started. Now if I was sport running I wouldn't heat the cells up to 135, just charge and run. Try and keep them under 140 and you should be okay.
