Good choice with the SS5800
I'm probably the worst abuser of the BL system around, my ratio is 6.5 and below.
I run it in ambient temperatures of over 90F.
I've shorted the unit by reversing polarity for about 8 sec's
with 6.8, at first it would shut down in the middle of the pack bcos of the heat,bcos of the gearing and also the heat from the atmosphere.
But after i've installed a tiny 5V fan on top of it, it's been coooool..absolutely no shut down no problems whatsoever. I've been able to gear to 6.4. I've even tried 6.2 but it was a little too fast.
My unit is still running like a happy puppy , so WORRY NOT.
last note: I'm not gonna disclose my real name, Novak's gonna void my warranty
