Concept:
https://www.youtube.com/watch?v=4NAWs_ZIPEYLooking for a hardware expert, and a DIY expert. Li-ion batteries are much more efficient in comparison to lead based for UPS.
UPS I got:
https://www.newegg.com/Product/Product.aspx?Item=N82E1684210212166.1 Pounds for this UPS, and only gives 47 mins for 300 watts. The person in above managed to do 2 hours and 30 mins for 300 watts.
Project Concept:-Using efficient compact Lithium ion batteries.
-Build a device that is superior in battery life, for example 500 watts last 2-4 hours instead of 30 mins.
-incorporate safeness into the build
-Have an LCD screen with status, battery life, wattage usage, etc.
-A nice case, preferably black
-Write a nice logo on this device called "Blue Power"
-Lighter then 66 pounds if possible, and of reasonable compact size.
Quote the BTC cost, for the labor, parts, and device.
