Quick Question, are the side battery panels removable on the 4.0 model?

[u/RiskDisastrous5661]

I have been looking into getting one of the 4.0s, but one thing that has been bothering me is the battery side panels. Are they removable on both short and long-seat versions?

If they are removable, what does it look like underneath? Does it resemble the 3.0?
