We have customers using our batteries with the Surface Book i7 without problems.
We recommend you still use at 12v setting which we set too (since our batteries will supply more amps as needed then Microsoft's own adapter, other battery sellers call this "auto adjust"), but if you are high CPU user and find it not enough, the16v setting on our battery will work too. If you are concerned about that, we can build a small box that will reduce the voltage back to 15v. But our tests (with the Book and with prior devices) show that a 1v variance is not a problem.
