Hi everyone! I have been researching and searching for a few weeks now and have not found any reasonable answers that I need.
To my Project:
I am building a Race Kart out of a fairly new Tony Kart shifter Chassis. It will be a purpose built race vehicle, so no need of any lights, horns, turn signals etc.
To my components:
QS 138 90h Motor and a Siaecosys Far driver 96850 controller with 450 Bus Amps. The battery will most likely be a 23s2p with ePlb c020 cells and 84V nominal and ANT smart BMS.
I will be wanting a simple Emergency ON/OFF switch between the battery and Controller in case of an emergency, something like the Albright E Stop buttons and a simple ignition on/off button instead of a key ignition.
My Questions:
Do I have to use a Contactor between the battery and controller? There are a lot of different opinions on this and I just don't know why it would be necessary. The lady I spoke with at Siaecosys said that the far driver didn't need a Precharge, so one thing less at least.
Is it possible to wire in a simple toggle switch instead of the Key Ignition? There is only one wire going to the key ignition so I am guessing I will need a ground wire, possibly from the anti theft?
I will be replacing all plugs for more durable sealed plugs anway so I don't mind if I need to rewire to use a toggle switch. The Reverse switch should work nicely with a normal toggle I presume.
Is there anything else to worry about or to install? A DC converter will not be necessary.
