How did you setup you cutoff?

You may find that to be a tad too high and runtime may be reduced (probably only by about a minute though). Like I said before, set it to whatever, run your vehicle until the LVC kicks in, disconnect the batteries and let them sit for about 10-15 minutes disconnected. After that, see what the voltage is. If it's over 3.6v, you could bring the LVC down a tad. If the voltage is lower than 3.5v, bring the LVC even higher.

3.3v might be right for your vehicle/battery combo, but the idea is to find a LVC value so that the batteries are protected, yet don't have premature cutoff. Also, an LVC setting too high may introduce false cutoffs because the battery voltage does dip on high current starts.
