I use these in my r/c models, they are 5AH cells but high current.

before I used them, I bought one of these
www.ampsplus.co.uk
but never used it as the charge density higher on the first battey is higher and can handle a higher discharge current, so under high current loads will last longer than the slight higher capacity (second battery)

I am.not sure yet how they get the 24 volts. Whether they use 1.2 AA or 3.7 18650 I am.not certain.I use these in my r/c models, they are 5AH cells but high current.

if you're using 18650's, Im using these
www.nubattery.co.uk
as I think they're best compromise between capacity and maximum discharge current

This is one of the replacement batteries.
So just weighing up the costs versus (possible) savings.

Agreed. Especially if a new BMS is required, unless you are aware of the replacement requirements.

I bought from NU Batteries, they're a small business and they test the models they sell in house. Just be sure to go for Korean or Japanese cells from a trusted shop that's verified their origin. The Chinese cells outright falsify their specs. Cell production is complex and not every country has the right capabilities to make them properly.
This is the new one. It's not cheap.
However I have see single cells for 7 quid so the same price if you count postage as 3 quid as i would need the tabbed cells.
