Oh, yes, I do have two of the TrakPower Gold packs (2s) - the photo was sent to me by FP showing a demo of the config I'd have...their photo shows 5s packs but mine are 2s...

They did send another reply today answering the question of why not build a super adapter for the one VB do do it all, it explains it quite nicely...here is that reply:

--FP--
It would be possible to use one balancer with a special harness but the
balancer is designed to shut off if it detects to great of an in balance
& wont turn back on until the balance is within tolerance. SO with your
situation 2 would almost be a must unless the voltages on the cells in
both packs were very close.
