They were insufficient and only worked for small electronics like televisions. Undeterred by this limitation, Kelvin decided to figure out a more efficient solution to power his DJ equipment.
He embarked on a series of experiments to develop a better power source for his setup, recognizing the need for reliable and long-lasting batteries.
He made many attempts, exploring various materials and configurations for his batteries. Despite encountering setbacks, Kelvin remained persistent and determined, learning from each experiment's outcomes. Through continuous refinement and adjustments, he kept trying until he achieved his goal of creating a reliable and powerful battery solution for his DJ equipment.
