I have two Granite Voltages purchased at the same time a couple of months ago. I noticed that one always seemed to run a few minutes more than the other on the same batteries. At first, I chalked it up to different driving styles and assumed my son was driving his “harder” than I was driving mine, but now I have started to collect data that suggests the low voltage cutoff (LVC) on his Granite is different from the LVC on my Granite. Yesterday, we ran both Granites with identical 2S 5200mAh 50c LiPo batteries to LVC (steering would still work, but throttle would not work) and as usual, mine ran significantly longer.
This time, when I put the batteries on the charger (Venom Pro Duo) I took note of the initial voltage. The battery that was in his Granite (that ran a shorter time) was 8.0V (4.0V per cell) and the voltage on the battery from my Granite was 7.6V (3.8V per cell). Both Granites had the battery selector jumper in the LiPo position. I haven’t checked the voltage after running with the 2x Lion 18650 batteries that came with the Granites, but the same run time discrepancy happens with them.
Has anyone else experienced an abnormally “high” LVC on their Granite? Even the LVC of 7.6V (3.8V per cell) on the longer-running Granite still seems high for LiPo that I thought could go down to 7.4V total. The documentation in the manual is so sparse I can’t even figure out the intended LVC for the different battery types...
