Hi, I have a various Display Units that are going to be free standing in shops. These units have motion sensors and LED lights. I need information relating to what my battery requirements are to power as per the rough specification in the attached spread sheet for a .2 watt unit, 1 watt unit, 3 watt unit and 5 watt unit. These battery units are required to last 6 months (approximately) before being recharged. I would like a series of graphs and battery specifications put together that detail battery requirement and a proposal of how to procure these batteries on mass. Thanks Bill

I can help you with this, for FREE. I've been designing embedded systems as freelance worker as well as on a full-time job for the last 6 years. I can certainly do all the technical work here - no doubts about that. However, since I am from India. I'm only knowledgeable about the Indian suppliers and may not be able to help with British suppliers. So send me the details of your work and I shall deliver all that I know. You need not pay me ; in fact you need not even 'select' me for this project - just drop me a mail and I'll tell you what can I do. I'm not asking for money because I love all things electronic. Good day!

Hello, Your project is interesting, and as an electrical engineer, I would like to provide you with efficient solutions to your problem. What you are looking for is doable, and the awesome suggestion I have for you that would lower the cost of the battery and increase your profits would be to incorporate a free energy power generator: Solar Cells that can work with ambient lighting. Feel free to touch base if you have any questions, Best regards
