The 1S 3.7V 600 mAh Turnigy Nano-Tech Litthium Polymer batteries are being sold by one of the largest online remote control model and accessory stores called Hobby King and the brand Turnigy is their own. The batteries under that brand are considered to be of quite decent quality and a very good value, though we are going to check how good their perform and if they match the official specifications. The Turnigy only batteries are the lower end and the Turnigy Nano-tech labeled models are considered to be better as they offer higher discharge rates and the 600 mAh Turnigy Nano-Tech 1 cell LiPos are labeled with a discharge rates of 35-70C (constant 35C and peak 70C) which seem pretty high for that small battery. These batteries usually find their place in small scale helicopters, quadcopters or planes, so it is very important that you know what they are capable of in order not to crash your flying RC model because of battery not handling as well as it should be and you now aware of its actual capabilities. Below are the official specs of these Turnigy Nano-Tech LiPo batteries.

Official Battery Specifications:

– Capacity: 600mAh
– Voltage: 1S1P / 1 Cell / 3.7V
– Discharge: 35C Constant / 70C Burst
– Weight: 15.8g (including plug & case)
– Dimensions: 79x7x19mm
– Discharge Plug: JST

In order to test the capacity of the 1S 3.7V 600 mAh Turnigy Nano-Tech Litthium Polymer batteries we’ve started with a 1C (one time the capacity of the battery or with other words 0.6A) discharge rate and continued to increase it to 35C, the value that the battery should be able to handle at a constant discharge (that is 21A discharge). Our tests showed that the maximum useable capacity we’ve got at 1C discharge rate was 590 mAh which is only 10 milliamps shorter of the 600 mAh capacity by specifications which is not bad at all. However the official specs about the discharge rates this battery is capable of are far from the reality we’ve measured. At 35C discharge rate (21A) the battery is not able to handle properly even peaks, let alone provide a constant discharge. We can say that the battery is more like capable of peak discharge rates of 20C and constants discharge rate of 15C, though at 15C discharge rate (9A) we’ve measured a temperature of the battery of 59.5 degrees Celsius at the end of the discharge cycle. This temperature is at the edge of the safe zone for discharge of LiPo batteries, even though this temperature has been achieved with the battery standing on one place and if you are using it in a moving RC model the airflow will help in cooling it a bit and the actual temperature will most likely be lower.

The performance of the 1S 3.7V 600 mAh Turnigy Nano-Tech 35-70C LiPo Battery in our tests:

– 590 mAh at 0.6A load (1C)
– 545 mAh at 3.0A load (5C)
– 531 mAh at 6.0A load (10C)
– 506 mAh at 9.0A load (15C)
– 69 mAh at 12.0A load (20C)
– 18 mAh at 15.0A load (25C)
– 7 mAh at 18.0A load (30C)
– 5 mAh at 21.0A load (50C)

So the battery is not bad, however the actual specifications are a bit lower than the official ones. If you regard the battery as 1S 3.7V 590 mAh with a discharge rates of 15C-20C you might save yourself some trouble in finding out these more actual values the hard way.
