Dual Resistor Battery Load Bank

This is a configurable resistive load bank for discharge testing 52V and lower battery packs. A simple rotary switch reconfigures resistors in series and parallel and allows you pre-select low, medium, and high discharge rates at the turn of a dial. Turning the dial under load will result in shortened switch lifespan!

The chimney style enclosure housing with bottom vents and insulated standoffs produce natural convection on all sides of the load resistors. This helps remove resistor heat and allows the aluminum shell to remain warm to the touch even with more than 700 watts of heat being dissipated.
