I need verification that this will all work before I put it together, can you guys help me out/suggest anything? Thanks.
Yep looks perfect! Be sure trough to never mix the connectors, the series connection wil not look that dangerous but it could leed to Sparks if you accidentally put the main power leads in parallel and you forgot the balance lead connection.
We should have a drawing contest to see who can make the nicest diagram
Are you sure the balance wires can handle 5a?
