Lithium and cable gauge: Does it matter?
I'm on my 2nd lithium conversion and have moved more into the performance category.
Both my RoyPow 36v and my new BigBattery HSKY 48v 6 AWG cables. BigBattery is also rated at 350 amps for 6 seconds, which is a fairly significant load.
I understand fundamentally the advantage of a larger gauge cable, but I also understand that it is a function of length and resistance.
The amount of cable used from the lithium pack to the controller is already 6 feet shorter vs lead acid and power is flowing from the highly available lithium vs the 6 lead acid batteries in series, which seems like it would also reduce the resistance of the system significantly.
Before I go spend more money, does a lithium cart even benefit from going to a larger cable?
