This\u00a0QD450A series chargers\u00a0are non-waterproof models.It uses a dual-tube forward circuit, with an auxiliary power circuit inside, and a low output start-up voltage.<\/p>\n

The appearance is assembled from an aluminum extruded shell and a metal bottom plate, and is non-waterproof. The input and output PVC wires are one-piece injection-molded wires, which makes it difficult to replace the power cord.<\/p>\n

Multiple Protection:Over heat protection; Over current protection; Over voltage protection;Short Circuit Protection;Reverse Connection Protection; Overtime charging protection. For lithium battery, there is Charge activation function.<\/p>\n

This QD450A series chargers design of unsealed structure. It suitable for flooded lead acid batteries, sealed lead acid batteries, Lithium batteries, NI-MH batteries, Nickle Cadmium batteries, etc. They ate used to cycle charge or floating charge battery pack in electric Bumper Car, Walk-behind Mowers, fork lifts, Floor Scrubber, AGV, ships, Electric Aerial Work Platform Walk-behind Mowers Electric Watercraft.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
