The float and equalization voltages defined in Table 19 are not an exact
requirement as long as voltages do not exceed -56.5 V.
See Table 7 in “DC
power description.”
Not all sealed cells require equalization, but the equalization voltage can be
used for fast charging.

Batteries to be used with the SL-1 should be sized by using an end voltage of
The noise limitations for a battery string are:

rms maximum ripple
32
maximum noise
End cells and
cells are not recommended because they are a noise
source.
