It's the additional communication between camera / battery, so battery runtime will show up on your camera instead of voltage. I believe this is reversed SMBUS, while the standard is regular SMBUS. I'm debating between the standard and RED versions currently, considering the battery displays runtime on the back anyway and I'd rather not corner myself if I decide to use these batteries in a SMBUS setting in the future.
Although, if any of this information is incorrect - someone please feel free to jump in.
Hey everyone,
Zack here from Core SWX.
I just wanted to provide additional clarity on the battery communication.
HCM-9R communicates exclusively to RED cameras.
HCM-9S communicates to standard SMBus devices as well as RED DSMC2 models. DSMC2 models have the ability to read both standard SMBus and RED's SMBus battery protocols.
Let me know if you have questions.
Thanks!
