Unfortunately they're NRS property so no modifications allowed!
Also I think these newer models have a higher idle power draw since they do self-checks, like it can tell when it's due for a service.

beause each of the 2 24v batteries has a barrel jack on it, which allows me to easily run my powerchair or other 24v devices from it in a pinch.

You have 2 problems. 1 hose packs are tiny 2Ah calls. Actually 18650 cells . They look like duracells. And there is 7 in series with a BMS. The BMS will limit current to something much less than a powerchair needs. And those barrel connectors are only good for a couple of Amps. A powerchair can pull 100 to 200A. And then theres the 29.4V battery voltage that will attempt to charge your dead batteeries in a chair at around 100A if you were to connect them. And the Barrel connector, its wiring will melt. If the BMS doesent cut off power first. If you try it you will ruin the cells too. You cannot take that much current from them. There are some specialist 18650s that can do 30A. But that will destroy a 2.1mm connector.
Those 2 AH packs in series run a 500W tiller successfully chewing up turf for over 30 minutes at a pop and recharge faster than I do.

If you keep using the hoist, it will hopefully build up a charge.

The reason it happens is that all those with any real aptitude for electronics, mechanical skills are capable of earning big money working for themselves or in specialised industries like aerospace or race cars, or whatever.
Whats left is all those that were not capable of that or much else and they chose the ultra un sexy mobility industry. Or usually it chose them. Why? The last "engineer" that I had here from the wheelchair services was a delivery driver 3 years earlier for a high street mobility shop. He had no clue, and almost no training. And this is typical. He was all they could get. He ended up as their tech because he could fix things that the sales guys couldnt. An "expert" is someone that knows or claims to know more than you do.
My mate dave syndrome! My computer (real expert) freind ran a computer shop. Specialising in networks etc. He said every time some numpty with a buggered up computer came to his shop, it was always because the customers "computer expert" freind had been messing with it. Inevitabley this expert was a typical tit who knew just enough to cock it up. And was usually "me mate dave wot did it".
YOU as an end user know 10x more than your expert about batteries and charging and have already fixed it. As he should have done. Now this isnt to say that ALL these experts are useless. There are a few. Like Rover who I never met. But seems to know his stuff well. But he is one in thousands seriously. And note that he is on here. Why are all the useless ones not ALSO on here learning and asking questions? Because they literally do not understand it, and worse dont give a crap. They only turn up for the wage. And they keep their jobs because to the secratary or boss they are an "expert" because they know a bit more than they do... Me mate dave...
