Morning Steve,  totally happy with Daly BMS, has programmable low and high temperature protection and I can verify it works, last year we had -10 F and it turned off the battery bank when it got to 38 F that I had it set at. Also has a blue tooth app that you can check what individual cells are doing. Has many parameters that you can program to keep the batteries safe.

The thick black material is 3/4 inch rubber horse mat from tractor supply and the black plastic box is a musical instrument carrying case for shipping instruments. You build your own batteries you have to improvise but there's a tremendous savings in doing it yourself more than 50%.

Jack,
Thanks for the horse mat tip....been looking for something like that for a project that is in the works.  I have been a Will Prowse You Tube viewer for several years now and his DIY battery packs are all about robustness and savings.
