Gale,
Does this mean you are going to "roll your own" battery management system?
It appears that I am leaning in that direction.
As to the contactors/relays, Tyco has one that fits my need it is rated at 260 amps continuous.
If this project gets out of hand I will probably go with the Battle Born or Stark Power batteries that have a built in BMS.
What I am currently looking is 8 CALB 180 Ah cells in a 2p4s arrangement.
Still studying BMS units.
The BMS needs to be able to disconnect or turn off the charger/converter and may need to also shut down the solar charge controller if I can't make the CC do it on its own.
The big latching relay is for low voltage cutoff.
Still tweaking the design for awhile so I am still open to constructive suggestions.
