Application — Compact lift drive power
Requirement — The challenge was to handle 24V regulated auxiliary power within one pack in the compact lift drive power application.
Solution — We built a charging module and a 24V regulated DC-DC converter into a LiFePO4 8S pack (DC 25.6V, 3.3Ah).
Result — A discharge configuration rated at 10A maximum (≤1.5s), housed in approx. 1.5kg, completes compact lift drive power in a single pack.
