You do have to select value 1 LiPo/NIMH mode to activate the cutoff. NiMH will work in that mode but one may not want a cutoff using NiMh (1/12 and to finish races if dumping) so you have the option to remove the cutoff completely.
Thanks Rick, I just leave on value 1 and forget it. Awesome speedo also, I've tried a few now, and the hassle free profiles and brake settings are perfect for me. Next one I buy I hope is updated with your pic...you deserve it...nice job
