Need help sourcing a battery case

[astroinfidel]

Hello all,
I want to build two 100 Ah LiFePO4 batteries for the trolling motor in my fishing boat. Like my first LiFePO4 battery that I built last year, I will use grade A EVE cells and a JK - BMS with 2 amp active balancing. Last year I used a battery box as a case, and a lot of the space I filled with styrofoam as it was much too big. It is also too tall to fit under the deck where the trolling motor batteries go.
So what I hope to find is a source of battery cases so I can choose two that are going to fit in the space required. I have been using 2 group 27 lead acid batteries until now, so that gives some idea as to the space I have available for the cases. It would be nice to find something that is a better fit that the oversized box I used for my first battery build. A bonus would be a case that I don't have to glue shut like the LiFePO4 batteries available on Amazon. They need to be cut open to get inside them. I want to be able to get into the case easily if necessary.
Any help much appreciated! I can use Alibaba or Aliexpress if one of those are a good source.

I know you said you want to build it yourself but wanted to mention Epoch batteries has pre-built battery for your use case.

DIY battery is probably not the best idea for a boat as it has no suspension on the water even at rest the chop hitting the boat causes stresses on everything in the boat including your battery I think a pre built off the shelf model with warranty would be your best option and save the DIY for the workshop or somewhere stationary.
