Assuming you're building your own 16S battery with EVE or similar cells.

And by "Smart BMS" I assume you mean one you can connect to and see the cell data, and not one that can communicate with a Cerbo or other GX in the system.

You'll need an MK3-USB adapter to program the MP.

Absorption:

3.45V/cell for a long slow charge with a 2-3 hour absorption period.

3.55V/cell for a fast charge with 30-60 minute absorption period.


Float:

3.375V/cell


If charging with grid, 3.45V is preferred. If charging with generator, 3.55V is preferred.

3.45V/cell minimizes stress on cells and should maximize cycle life.
