Hi I am a High School senior and I have been building OpenROV v 2.7. I need to have it completed by the end of the week and I am almost done. All I need is the batteries. I ordered the ones off of the website a week and a half ago but still haven’t received them.
Any ideas on alternative batteries other than the Li-FePO4 batteries that I can use for a day to demonstrate my project for my school?
