At 51.2V, 150A is about 7,680W of DC power before inverter losses.

Tighten the terminal bolts securely without over-tightening the threaded inserts, place a DC-rated main fuse or breaker as close as practical to the battery positive terminal, and confirm polarity with a multimeter before the final connection.
