He's going to 56 CALB lithium-ion modules and the top-end voltage under charge is ~190 but
regen voltage could be a bit higher (though he could reprogram his controller to limit
that). His current DC-DC is a stock Solectria unit (probably has a Vicor brick in it). If
it can take up to 200V, then it could work.

What voltage is he upgrading it to? He could simply replace the Vicor bricks he has now

Solectria used some special Vicor bricks with a nominal 200vdc input, which covered the
150-250vdc input range. The standard bricks are usually 150vdc nominal (100-200v) or
300vdc nominal (200-400v).
