Default Re: Please review my buy list for lithium build

I never heard of a EVM53, Zeva has an EVMS3 Controller but you will also need two BMS12v3 to actually balance the cells.

The EVMS monitor is pretty much mandatory for your setup or you will not be able to configure it properly.

Leaf cells need to be under compression the entire time they are charged or discharged to avoid failure.

The four threaded rods do not apply pressure directly on the pouches, the unique tray shape of the case acts as a "spring washer" to provide the proper compression inside the modules.

It is important that if your particular modules came with any spacers that they are installed as to preserve the original width profile.

When properly torqued and compressed the distance between adjacent modules power taps should be 1.3333".

I have seen lots of designs online (and some in this site) where plywood is used for end plates, it is your choice.
