That'l do it. Glad to see you at least identified the problem.

I dont know if you have room, but try running 2 of those packs in parallel just to verify that a battery that holds voltage better solves the problem.

I think the reason the MM doesnt kick out is CC put a timer on the LVC in the MM. It needs to stay below the cut off voltage for a few seconds before it cuts out.
