I've built a working prototype of an off-grid cellular powered security camera powered by solar panel using an agm battery and an oversized 100w solar panel.. i'm looking to refine it and make it smaller and more efficient with lithium battery. i saw this post: https://dakotalithium.com/2019/10/30/what-is-the-best-battery-for-cold-weather/. the picture in stahlin enclosure is something like i'll use. temp in mn get to -20 degrees. my draw will be around 10w for hotspot and camera. i'll prob need to add some sort of elec heat, which is another 40w if running. that puts me at 50w max per hour.
I wouldn't need any heat if my mobile hotspot operates in extreme cold. According to Dakota's website, their lithium batteries work at -20 degrees. questions:
- 10a 12v battery seems like could be good fit?
- do i need a charge controller if charged by solar? currently i use a cheap one with my agm.
- 25w solar panel big enough (assume 5 hours sun a day)
thank you.
