Your battery pack could now be plugged into your chair, in an emergency if the chair runs out of steam.
And it could be left connected all day as a long range system too if you want. That way the chair and vent run off a common large supply.
And your vent can be powered fron the chair in an emergency as well as the new pack. 2 options for breathing. Options are always good.
So adding a 24V out anderson to the chair, and the 30A pack may be a good idea.

I hope you mean 3.3x volts!
I would like a BMS with bluetooth.
Not to charge them or anything.
I can keep an eye on the power as I go along.

The purpose of a BMS is twofold.
1. To cut off power at every inopertune incorrect moment such as when trying to climb a curb off a busy road. In an attempt to protect a too small battery back from damage. You dont want that...
2. To balance and try to prevent a dumb charger from destroying your battery (which thay are crap at).
What you are looking for is a battery monitor. Which you have already in your joystick. And if you fit the right sized pack wont ever move from full before YOU run out of steam. When it shows half the battery is done, ots fully done and you must stop. Or just fit a voltmeter Dont go past 3.1v per cell. So 24V. ever.
