Thanks for the feedback.Nice setup. Only concern when using parallel BMSs is, if there is large load and the other decides to cut off power fraction earlier, other might burn. They would need to be designed so they can be used in parallel. Other as a master unit, other as a slave.
The only reason I don't think it is a big concern, is that is exactly the setup I would have if I had gone with a commercial solution like Battleborn...each of their batteries has a BMS in them, and would be hooked up in parallel for a 12 volt system.
