I am experienced in battery packs and their charger controllers, PCM and fuel gauges - currently working on similar project. Also, we(as company) are creating our IoT platform for GSM connected devices so I am familiar with the matter. I am professional, working with electronics for 6 years now. If needed, I will send you my references. I am able to create proof of design in offered time. Afterwards, the schematic and project description will be sent.

Hi, I understand that you are going to design a product which is an outdoor power supplier. But I don't have any idea what type of parts you are going to use and how much you are going to spend on this. However I do have a lot of ideas to add as well. So if you are willing to chat, Yes I am totally open for that. I checked on ebay for the batteries(usually lipo), solar panels, Arduino, etc and I think we can finish the whole thing for less than 50$. So if this goes for mass production, prices get even lower. But if depends on quality and all that. Anyway if you are interested let me know. Thank you.
