Multiple LiPo Battery Charger



The University of Idaho Marching Band has been incorporating multimedia displays into their performances, including synchronized light emitting diodes powered by Lithium-Polymer battery packs. There is a need for a charging system capable of charging approximately 200 packs safely and efficiently within a one week time frame.

Background
A device which can charge multiple lithium polymer batteries is something that is unavailable in the current market.Charging the battery packs simultaneously can save a lot of time and effort. Also, the the circuitry to design the aforementioned device is one that can be achieved under a moderate budget. The prototype and the circuitry can be multiplied and extended as the number of batteries to be charged increases. Further improvement of the circuit can also reduce costs.
