Pulse raced into a 12-1 lead with barely 10 minutes on the clock, forcing Mavericks coach Tamsin Greenway to call an early tactical timeout.
Emma Thacker scored three two-point super shots as Mavericks cut the deficit to four points by the end of the third quarter.
However, Pulse finished the match strongly to claim a victory that moved them level on 18 points with league leaders Loughborough Lightning, who face Nottingham Forest on Saturday, 11 April (19:00 BST).
“We knew we had a very strong first quarter, but then had to push on. We know we let them back into the game,” added Fadoju.
Pulse head coach Sam Bird said: “I’m pleased with how we finished the game. We showed we have a lot in the tank to finish strong.”
On Saturday LexisNexis Dragons host Birmingham Panthers in Cardiff live on BBC Sport (16:00 BST), before Manchester Thunder take on Leeds Rhinos (17:00 BST).
