Voltage Selection Guide
Understanding Forklift Battery Voltages
Forklift battery voltage is determined by the number of cells connected in series. Each cell provides approximately 2 volts, so:
- 24V = 12 cells (12 × 2V = 24V)
- 36V = 18 cells (18 × 2V = 36V)
- 48V = 24 cells (24 × 2V = 48V)
- 80V = 40 cells (40 × 2V = 80V)
