On the off chance that it helps...
Before building a custom battery I ran my mower (RM480e) from this battery without any inrush problems.
Interestingly, as it has a clear case, I could see that it had the same 100A JBD bms inside that overkill solar rebadge as their own.
I'm in Australia, and this is an Australian brand, so I'm offering this as possible useful information rather than a solution
(unless you're in Australia of course). Perhaps there are other battery manufacturers using JBD bms's?
I'll just add, it's not a perfect drop in solution as the centre bolt can't be used, so it requires a tray and a strap.
