Hi I'm very new to ebikes and to Endless Sphere and I wanted to see if someone here could help with a problem I am having. I am using a Magic Pie 3 rear hub motor with a 48v LiFePo4 battery from Golden motor Canada. The problem is that when I put the motor under a heavy load (fast acceleration) the motor/battery cutout, all power is off. When I turn the battery off and then back on again I can ride for another block or so before the same thing happens. I recently hooked a cycle analyst up to see what was happening, starting voltage of my battery after a full charge 53.2v (this is leaving it plugged in for over 12 hrs although the charger indicates that it is finished after maybe 40 minutes?). When I watch the voltage under load it may drop down to 45v under heavy load and then jump back to 52v, am I having a low voltage cutoff issue. I have measured the voltage of each individual cell and they are each 3.2v. Also I measured the voltage output of the charger and it is 58.2v. Shouldn't my battery be closer to that after a full charge? I am sure there are a lot of dumb questions in here and perhaps I have left some important details out, please let me know. Thanks in advance
