Some of those style chargers do that. I think they got cheap with how they make them. Either there’s no hysteresis or the hysteresis is set wrong.
The fan will start going on/off/on/off/on/off/on/off/on/off/on/off/on/off/on/off/on/off/on/off for like ten minutes right at the top of the charge cycle. It’s just a wonky charger and annoying but it seems to work fine.
Just view it as an audible “I’m nearly done charging, you can ride now” signal.
This is a separate problem probably but not certainly unrelated to that.
If you actually only have 60 cells then that will work, but erm, it’s wonky af.
There are also a couple wires that will be stressed a tiny bit more than others and you could bump up to the next AWG size. But it’s only a 60% / 40% difference, if your wire is already more than big enough it’s no big deal. Just 20% higher currents through these 4 wires:
Well 16s4p has more cells so higher total watt hours so more range, also higher voltage is faster and more efficient so even more range and better top end which improves efficiency further
Catch is you need a high voltage ESC like a uBox, Stormcore 100D, or Trampa 75xxx. Also less torque
However if you change the gear ratio the speed and torque thing means nothing
The biggest problem with moving up to a higher voltage will be a far fewer number of controllers you will be able to use, and those controllers might waste more energy as heat than the 60V controllers will. However the rest of the system besides the controller should run cooler overall. And the controller might not run hotter.
It’s very complicated really.
Your enclosure holding a 8x8 grid of cells is likely reason enough to use 16S.
If you’re doing a good order of operations, then this won’t be any problem at all:
Well maybe but the bigger issue is that a lower Kv motor will have a higher winding resistance which is going to burn off more energy as heat inside the motor.
