sea jump 3PCS 3.7V 180mah Lithium Battery with 3PCS 2.0 Interface USB Charging Cable for A20 A20W Four-axis Drone Remote Control Helicopter Spare Parts

Those drones never seem to last very long or at least not for me. It's nice to have extra ones. Great buy. Good quality and value.

These were recommended as spares for potensic a20/a20w and other variants of the udi micro/mini series drones.They only last about a minute and a half, factory batteries are nearly 6 minutes. At first I thought I just had a battery but all three have approximate flight times. Waste of time and money

This battery had a different connector than the original battery for my remote control helicopter. I had to cut the wires and solder on the old connector, so this allowed me to install the new battery in the helicopter. This worked, but I'm not able to use the other 2 batteries since I only had the one battery that came with the helicopter. But if the connector is the same as the one you have, this is a good buy, especially since it comes with USB cable for charging.

Simply doesn’t work.

I love that these come with their individual chargers. These batteries work great for little projects and for prototyping. Batteries have a decent life, and charging is easy. I really appreciate the detail of planning that went into these batteries. The batteries do have a board on batteries to prevent over charging; this is a great value added to this great deal.

Batteries are damaged and only 2
