DIY: Building a Mini (220mm) Quadcopter Part 4 – The Battery
(This is part of a multi-part series on building a FPV mini 220mm quadcopter)
You need batteries to fly a quadcopter. The battery we selected will be used to power the receiver, flight controller, the OSD, FPV video camera/transmitter and to power the four motors that spin the propellers and give the quadcopter the lift it needs. As you can see, the battery is very important and also adds the most weight per single item. We’ve selected the Turnigy nano-tech 1500mah 3S 35~70C Lipo Pack to power our copter.
This nano-tech battery uses lithium polymer chemistry and are built with an LiCo nano-technology substrate that improves power transfer making the oxidation/reduction reaction more efficient. That means less voltage sag and a higher discharge rate than a similar density lithium polymer battery.
When sourcing a battery, Steve liked and suggested the need for the “70C Burst” capabilities. Two of these batteries were ordered, only one on the copter at a time — just gives more flying time. He suggested minimum three batteries on hand…
Voltage: 3S1P / 3 Cell / 11.1V
Discharge: 35C Constant / 70C Burst
Weight: 129g (including wire, plug & case)
Balance Plug: JST-XH
Discharge Plug: XT60
Also ordered some XT60 male connectors with silicon leads, need only one but they come in a 5 pack.
Total Weight So Far: 144.8g
Part Cost: $38.01
Total Spent So Far: $143.24
Both parts are available for purchase from Hobby King
