im going to replace my balance cable connectors from 3 mt30 connectors to a single DB9 connector. while keeping the main charging cables separate using a SB50 connector.

If going to the trouble of doing that why not use a single connector for charge and balance as I do?
This lets me make lots of jokes about my 'cordless' drill that runs off my chair....

I have one or two on everything. Drills, aboyt 10 chargers inputs and outputs, vehicles, chairs, my bed, inverters, solar system panels and connections and outputs in my room, lots of things like car polishers, etc. Even on my RC stuff like the goggles I use on FPV planes and quadcopters. And on my patient hoist. That thing always has a partly dead battery. It frequently refuses to lift me even if full as the batts are too high impedance. And it just bleeps. It only does about 3 lifts per charge even if the batt is new..

My chair that is still on lead bricks, I have the main charge / power wires done w/ PP-75 powerpoles in a compact 2X2 block, w/ a matching jumper block to bridge the two 12V batts to make 24V... I then put a pair of wires to a smaller pair of the PP-connectors across the otherwise empty 24V pins, which I use to connect anything I want to run off 24V...

Ditto... I too have a cordless drill.Now its corded. It runs better off the chair. Or the van. Or the lawnmower. Or the solar system. Or any of my power supplies or reserve battery. Or wherever I happen to need it. And its always "charged".
Hacksaw, black epoxy, soldering iron. Much cheaper than a new battery. When I say everything has an anderson on it I mean it!
