Pack Configuration Examples
- 23S pack: 2 x LTC6811-12S, configured as 12S + 11S
- 27S pack: 3 x LTC6811-12S, configured as 9S + 9S + 9S
- 29S pack: 3 x LTC6811-12S, configured as 10S + 10S + 9S
- 30S pack: 3 x LTC6811-12S, configured as 10S + 10S + 10S
- 35S pack: 3 x LTC6811-12S, configured as 12S + 12S + 11S
- Für ungleichmäßige Zellzahl in Serie, only the last slave board in the daisy-chained loop should have one fewer cell connected than the other slaves.
