Radian Vmax

Hi All,

first time poster. <Neither framed nor laminated> :lol:

I read in the tech specs that the Vmax for a connected battery pack is 64VDC. Is that Vmax a nominal value, or is that a not-to-exceed value?

Many NCM cells are not quite fully charged at 4V/cell or 64V for a 16 cell pack.

Thank you all for the fine info already here.

Cheers!

Jim

Hi Jim,

The 64V is the max value that you can program the Radian for absorb and float (not sure why you would do that). The High Battery Cut Out (HBCO) and Equalization settings allow up to 68V.
