We installed two Epoch 105 AH replacing two 100AH BB batteries on Ollie. We don't have factory solar charging and only have an onboard Progressive Dynamics 45A Lithium charger. The BB worked nicely with this setup.
The Epoch 105AH batteries are a little smaller physically and lighter than the 100AH BB batteries. I like the carry handles on them, too. The new Epoch batteries with the carry handles are easy to install and remove on Ollie. I removed them in less than 10 minutes when I put Ollie in storage this winter. It will take a little longer to install them later this month. Really like the Epoch app, too.
Edit: I looked at the Epoch 105AH link in your post and thought you were installing 105AH, what ever size is used, they are very nice batteries.
