Nostick,

I am new to this boat so there is a lerning curve for me in the boat but one thing I can tell you is I never run my packs out in the car/boat/plane. I made a light discharger years ago. Not positive of actual amps it pulls but what I do it measure how long the batterys keep that light bright as when it started, when I feel it starts to fade I consider that time to stop the run. Like I got 2 sets of 7 cell 4500 Tenergy packs, they last 10 1/2 min on my bulb discharger, the light looses it full brilliance about 10 min, so what I am saying is you have to guage how long to stop beating up the pack, if you know what I mean. These new 7 cell 4500 Tenergys are fine, I have no heating issues. When the new 4500's come out in 6 cell packs I will pick up them and see how they do. Worst case senerio, I pull the pack apart and redo it side by side because the cells themselves are good, the way there assembled might need help.
