Hi Nick There are PF16's running open loop with Radians. The PF16 has a precharge built in. The key is to have the inverter breaker closed, then close the battery breaker. After that push the BMS power button (3-4 seconds the display will power up) and the battery will slowly ramp up and do a precharge before fully starting.
Reach out to me off the list and I can help you more if the "new" radian does not work.
