Inverter capacitor charging spark!

Usually LiFePO4 BMS OCPD is triggered from charging most caps, but yeah if you are doing raw cell system, get a resistor on there and pre charge them. Hightechlab covered it nicely
Thanks Will,
I am planning to use an 8 ohm 50 w resistor to precharge 3000 w Kisae from 2 200 ah Lifepo4 12 v batteries. I believe this would give 1.5 amps at 18 watts. Is that the proper resistor? If I turn off inverter for a couple of weeks and turn it on do I need to disconnect at battery and reconnect with resistor when ready to yurn inverter back on?
Thanks Richard

As long as the battery remains connected to the inverter without a physical switch at thw battery, you are fine.
