Review on Power Your Quadcopter With 4 3.7V 500MAh Lipo Batteries And X4 Charger Set - Compatible With UDI U818A RC Drone Series by Tim Armstrong

Revainrating 1 out of 5

About 10 seconds flight time in U818A HD.

Got these for my daughter's U818A HD drone we got for her last Christmas. Original batteries were worn out so tried these. BIG mistake. Only 10 seconds flight time on full charge. Complete garbage and borderline fraudulent. Throw them in the recycle bin as soon as you receive them if you are foolish enough to purchase them.

Pros
  • Works great
Cons
  • The batteries may not be covered under manufacturer warranty if purchased separately
