In battery terms 11s is a non starter if you want to use a bms, 12s makes sense both bms and chargers for 43.2v nom are available.Ok sorry to jump in here am rereading this thread as I am awaiting a yosepower 36v 350 hub and bits to build batteries, saw this from
................my question at tbe end...................

No hall sensor 3 wires only = square wave.
Both controllers are hall sensor & sine wave both give quieter smother operation the only difference is 15a one is for 36v though can be used up to 12s with max 4.15v max cell charge to be on the safe side 4.1v, it has waterproof easy fit wiring.
17a version is a dual voltage model so can be used with 36 or 48v even to the point of using trying up to 15s to a point if so wished.
If the requirement is to use 36v and in need of a few more amps/watts then a simple shunt mod on the 15a controller can increase power output by another 25 or 30% if required.
................MY QUESTION IS ............
What if Ibuilt a 12s (or 11s or13s ) Battery what would that do to the whole setup, just throwing this in here as I am also new to lithium batteries, though a friend has more experience, maybe its not even possible or worthwile??, ok back to rereading 3rd time around
thanks in advance
