Sterling PlanB Battery Testing

Nail Penetration Test

Nail penetration testing is a type of safety testing done to simulate internal short-circuiting. The sample battery is penetrated with a nail to simulate an internal short-circuit and verify that the battery does not catch fire or burst.

Over Voltage Test

A single cell is fully charged to approximately 4.2VDC, other cells are set to 3.2VDC We overcharge the battery at up to 6VDC and 75AH until the cell fails and becomes a resistor.
Sterling PlanB systems use the industry’s most advanced cells, with the highest energy density in the market.  Coupled with our CellCool technology enabling all cells to consistently operate at optimal conditions, our systems can achieve incredible power outputs, and operate at an average continuous rate of 300% to deliver power boosts.
