YX F08 Battery

Really love the cartridge-type batteries. No separate charger needed! Just plug the charging cord into a USB port and wait for the full charge indication. Brilliant.

I ordered a battery. A few days later it came. No fuss, except for the interminable emails demanding that I rate the transaction clogging up my email.

So, HeliDirect did their job, the USPS did their job, and I guess I my job too?

The difference being, both HeliDirect and USPS got paid for it.
