Except swoozle has a 6S module (22.5v) there... Which will basically get destroyed if it's paralleled at module level with the 12S (45V). (option2)

Sorry guys, I swear I saw a 6S in parallel with a 12S. But there's no such thing, so I should probably stop posting before I have my coffee in the morning.

Coming back to the topic at hand, I am also in the design phase of a Chevy Volt pack split in 2. And I am considering the following:

• 2 parallel strings 48S3P
• each string with contactor
• string contactors commanded by charger&BMS
  • Charge Cycle - contactors closed, single charger for both strings
  • BMS command - stop charge & open contactors when first cell reaches top charge setting
  • Balancing cycle - both contactors open.
