60A on a 50A controller

[WillQ32]

If my controller is 50A can I use a 60A battery on it? Will it effect my controller?

It's always better for the battery, if the battery has some headroom above the load it needs to supply. The controller will consume as much current as it needs, up to whatever limits are programmed into it.

The controller, not the battery, sets the current. Thus a 60A capable battery will only deliver 50A into a controller, since that's all the controller will pull.

(Note that if you exceed the current rating of the battery - say you use a 30A capable battery for your 50A controller - you may damage the battery and/or cause the BMS or a fuse to open the circuit.)

I was thinking of making my own 18650 battery pack and was watching some videos and they said that they have a charging and a discharging cable. Do I have to discharge my battery each time if so to what voltage?

No, if you ride till its at 1/2 charge, it can sit there for a very long time with no damage.

You can charge and discharge from the same cable, but then if you only have one cable, you would have to unplug it from the controller to plug it into the charger.

By having two cables, it makes its easier. The charging cable is typically using 5A, so the wires can be light, maybe 14ga. I recommend a female XT60 for the charge cable.

For discharge, the bike can often use peaks of 30A, so I'd use a thicker wire, maybe 10ga/12ga. A female XT90 connector is a good choice on that cable.
