This power supply was designed as a prototype delivering 3.7V for long periods, with the ability to boost electrical energy on demand for robotics applications. It utilizes five 3000mAh AA Li-ion batteries, which discharge into a 100F capacitor until it stores maximum energy (684.5J) and powers the load sequentially from each battery. The batteries can be fully drained and charged in succession for optimal efficiency. A common 2.1mm DC plug is available for charging the batteries, with 10 MOSFET gates on the PCB (five for running, five for charging) and seven current-sensing devices monitoring cell drainage, charging current, and load current. The lid features holes for positive and negative cables connecting to the load. With the right microcontroller programming and wiring, this system offers a 200.5KJ Penstable series battery capable of releasing 684.5J in one boost (equivalent to 0.9 HP applied for a minute) and over 300 boosts before depletion. While charging, the empty cells can be powered while the active cell runs the load and charges the capacitor. The creator also has more advanced energy products, including a 2.4MJ system in a one-meter robot reaching 1.8 meters. Connect on Facebook for further information.
