Compact, lightweight, battery operated, self-priming, positive displacement pump for storing in a toolbox or tool belt includes an elongated housing having a longitudinal axis, and an inline configuration including a positive displacement pump assembly to respond to a motor assembly drive torque, self-prime, and pump fluid from an input port to an output port, a motor assembly to respond to signaling and provide the motor assembly drive torque, a pump control interconnect assembly to provide the signaling to control the operation of the motor assembly by current based on run dry mode or over current, by time based on a timer set to run for an amount of time, or voltage based on over/under voltage; and a rechargeable battery housing/assembly to respond to recharging signaling and with a rechargeable DC power supply and power control module for providing some combination of inrush, overcharging, over-discharging, short circuit, over current protection. |
