Personally, if your Daly (real or knock-off) is doing it's job as a BMS I'd be tempted to keep it and add a high-current (5A) flying capacitor balancer.
Plenty on the market from multiple Chinese sellers, seem to be much of a muchness.
Flying-capacitor balancers can transfer charge between any pair of cells (not just adjacent cells) so you don't throw away energy, just move it.
We have one of these looking after our very worn ex-golf cart cells.

Note:- For 16S just leave the 17th wire unconnected.
