I learned a few lessons while testing a 5s lipo on my Cinestar 8 without telemetry...I'm not going to go into details, so let's just leave it at this: The velcro straps are great, but they may not keep your batteries where they belong upon sudden impact. I wanted to share an inexpensive "just in case" type of precaution. Your local hardware store most likely stocks a product called 3M Dual Lock Fasteners. I placed 2 strips on my battery plate and 2 strips on each battery so that I can first lock the battery in place and then strap it in. Trust me when I tell you that you don't want your batteries flying off of that plate and smashing into GPS & Navi, before going into the props and creating a real issue. Photos below.
