I have an Orion BMS, went through it's manual a few times and they mention nothing about max driving current for the contactors.
Does anyone have any idea?
My contactor requires 500mA
I have sent them an email and they don't reply :(
 
I'm no expert but did build a 45 cell pack with original Orion BMS and I believe the limitation is 100 or 175 milliamps depending on the version. I used a small relay between the BMS and the contactor coil. the small relay is fed 12 volts and the Orion sinks or grounds that relay to complete the circuit.
