@electrictech09: Turn one old battery into a monster power bank. A 12V sealed lead acid battery, two LED strips, two rocker switches, a car socket, and a 4-port USB module. Emergency light for power cuts, 12V output for car gear, and four phones charging at once. All from one old battery. 📌 Save this for your next power cut. What would you power first with a pack like this? ↗️ Share this with someone who needs it. #powerbank #diyelectronics #battery #emergencylight #maker

Patrick :
Why not but you missing the critical part a charge/discharge controller without the Battery would be dead after few charges or at least when you drain it fully one time.
