This device is a custom-built, portable DC bench power supply with removable back designed to run on a 24V Kobalt lithium-ion power tool battery. It serves as a versatile bridge between high-capacity tool batteries and delicate electronics projects, allowing you to take "bench" power anywhere from a workshop to the field.

The heart of the unit is a digital buck-boost converter module (similar to the RD or DPS series), which provides precise control over output: https://www.amazon.com/Converter-Regulated-Adjustable-Protection-Controller/dp/B0F1MDPSWZ/ref=sr_1_4?dib=eyJ2IjoiMSJ9.VQ26J6Hwlnf4srC1Pq_st99esNhJxruutLLzYRWsy-0LqqW9q66_X4uUf8EjicxIKBWnOvnfDKFKmlHBn40repw5W6GxiDqeW5L2GU0ceDTr1maSJx6gMMIYzcJD1t3YH-spy8Pa4MLQodPEyRr9i_D81M_JPdFVmgjsweko2WuXOSAWEQG8zVwZtKBJpf4RTyh0UWK10RSF80c5LR0BlcGEbl4qQ9LIuMInSjebyMQ.tiBq57YdwnSTjG8QDelEqOuYV0bWXxCTRJmUT-QGhm0&dib_tag=se&keywords=buck+converter&qid=1777410085&sr=8-4
