Great looking work! Jeff
How did you "size" (choose) the 2700Uf 25V Capacitor?
Is it spiced into the pos. and neg. with the ccbec and fan?
I would keep an eye on the bottom of the battery for marks from the holder mounting screws and maybe cover them with plastic or something if they are marking or touching the battery as the foam gives.
Enjoy your work and thanks for sharing
