How to test a salvaged controller

[CONSIDERABLE SHOUTING]

Hey ya'll, I bought this controller for $4 from a reseller and I have no 48v/60v battery to test if it even works- a Chinese friend of mine has translated the plugs and has found it's likely from an elder's transit vehicle, so in exchange for only being around ~1500 watts with no regen it has provisions for things like alarms and brake lights. I also would be powering it with a pack made from salvaged cells, so it fits the theme.
I have things like basic lithium chargers, including a Yarlan of some kind thats at least 48 volts. Is it possible one of those could be used to power it? Thanks!

Yes, a 48V DC charger could be used for testing the controller with no load (motor).

You got 3 space heaters in that box.

Hi,

Most controllers have three phase wires to connect and three hall effect wires plus voltage and signal ground, they need to be attached to the motor, the controller will also have two wires, usually black and red that connect to the battery, you will also need a throttle that is three wires and usually connects to the controller. You may need a corresponding LCD to power up the motor controller, you can search for one corresponding to the serial number. I know its a tough test - you might be happier just buying a working kit!

You need a motor to really test it. I have a very small motor I use for testing and just run it off a bench power supply. A larger motor will need more current but you can test with very low throttle setting to see if it runs.

I was thinking that- I can likely do it with a HiGo to Molex converter (if that exists) and I have another basic display that will read up to 48 volts so I think I have an option, but worst comes to worst I'll be out $4 I needed to snag some HiGo to JST converters anyway for past motors I scored.
