I thought i will give the quark monster pro 125 a chance it seems to be a good controller.

I´ve one question: Does anybody use the quark with A123 Cells? Is the Quark programmable so that the LVC will _NOT_ kick in to early? Don´t get me wrong i do not need a LVC for the A123s i just want to shut the LVC off.

One can configure quite a bit regarding LVC (i just read the Quark Manual) but i don´t see a possibilty to shut it off.

I don´t understand how the Quark determines who many cells are connected to it and how it calculates at which voltage it shuts off.

To make it short - does anybody use the Quark Monster Pro with A123s without problems?

Thanks for some help!

Marc.

I use the Quark 80amp ESC and A123 cells with no problems. The 80 amp and the Monster Pro have the very same settings.

I set the Lipo cut off to it's lowest setting of 2.2 volts per cell. A123 recommends a 2.0 cutoff for their cells, but by the time they hit 2.2v per cell, they are pretty much done anyway.

The discharge curve is very flat for A123's.

I hope this helps.

Thanks for the information!

Does anybody know how the quark determines how many cells are connected to it?

The controller cannot know how many cells are connected to it (lipo has another voltage than fepo4, than liion... and so on) - so how does that lvc thing work?

How does it determine when to shut down?
