Another approach that will probably provoke some controversy here is to tap 
your battery at the DC:DC's nominal voltage.  This will create an imbalance 
in the battery.  How bad that imbalance is depends in part on how much power 
you need from your DC:DC.

Yet another way to do it, crude and somewhat wasteful, might be to build a 
lossy regulator circuit to drop the battery voltage to the DC:DC's voltage. 

Here's still another thought.  I have a slightly-used Todd PC20LV 96-volt 
DC:DC here, and also a used Curtis 1400E 72-96 volt DC:DC. Both were in 
working condition last time I checked (January 2019).  You might be able to 
connect each to half the battery, and sum their outputs through diodes. Not 
100% sure, but I think you can trim the Todd's output to try to balance them 
a little better, so they share the current more evenly.  If you're 
interested in trying this, contact me off-list (see the bottom of 
evdl.org/help ).  I'll let them go pretty cheaply.
