description:

SBS batteries by default send broadcast messages to SBS compliant chargers to
|
|
configure max. charge current/voltage. If your hardware does not have an SBS
|
|
compliant charger it should be disabled via this property to avoid blocking
|
|
the bus. Also some SBS battery fuel gauges are known to have a buggy multi-
|
|
master implementation.
