Quark 80B Problem - Help please!

[BrianG]

The "high" modes simply allow the ESC to pull whatever it needs to get it to run. But, you may need the best cells. The "normal" mode is a little more gentle on batteries. I like to run on NiMH "normal" or Lipo "manual" (and then set the LVC point to 3.0v/cell). There is a torque limit or punch control function (can't remember what it is called at the moment) that may help too.

I'll try the NiMH normal tomorrow. I also run LiPo Manual and also at 3.0V/cell.

And because you also got a Quark ESC, you could probably answer this question to: In the manual it says "OPTO modification must be applied when using a battery pack above 10 cell NiMH or 4 LiPoly cell." Does this mean I can just drive with 4S LiPo and if I use 5S or 6S I should use a UBEC?

Just asking for safety, don't want to do something wrong to my lovely Quark (Yes I REALLY love that ESC)

EDIT: Btw, you've got 2 Quark 125B's, right? On how many volt do you run them, and in what cars?
