Default Will ESC protect battery from overcurrent

Hi everybody,

I have a 18650 battery set, I made myself. It's 4 cells set(7.4v). I've checked the manufacture's home page and know that the max current for each cell is 5A. And in all, it has a max current of 10A. But that doesn't feel enough for RC.

I'm wondering if it's possible to config the ESC (hobbywing 1060 brushed) to throttle the max current to 10A. So that I'm not risking myself with the explosion. I don't have too much demand on speed. So as long as it's safe, I'm happy.

That is not something that ESC can do.

Typical ESC's are designed to pump out as much current as possible from the battery to the motor limited by the PCB design and the MOSFET rating, never seen an RC ESC with current limiting for drive. You could do a wattage test on the motor and limit the throttle EPA to just under the max watt draw you desire to protect the cells.

The motor is what determines the overall current being drawn through a system, a common misconception is that an ESC "puts out" power. It merely channels it, and when you draw too much current through it and exceed it's limits that is when ESC's burn up. So to answer your original question there is no way to limit the amount of current other than taking your time to monitor operating temps and adjust gearing accordingly. We have a good quick read on some setup basics: https://www.rcjuice.com/power_system_setup

Our Mamba XLX does it but it's limit is between 120 and 400 amps, so it would not work for the thread starter's situation.
