I expect small adjustments will be made to allow teams that need to use a battery from Spare Parts. My recommendation to those teams would be to convert their robot to the SB50 connector if the need to use Spare Part batteries arises.
And while I am Chief Robot Inspector, I am not GDC and this will still require clarification in the Q&A.

Here comes my first of many warnings...
The 2015 motor rules that allow unlimited numbers of some motors does not imply that the electrical system can support multiple motor designs. A fully charged battery can supply more than 500 amps but at a vastly reduced voltage for a short time. Continuously demanding large currents from this system will lead to early battery discharge (and shortened life) and/or main breaker trips. Your mileage will vary.
