Here at Done Insdier we use Drone labs for the simple reason that they have the best mix of quality and price competitiveness. We tend to use the 1500mah batters for our 250 quads and get 3 to 4 minute flight times. We have 15 1500mah which we use for flights and general testing and as of yet they haven’t puffed and we bought them 4 months ago. The only issues we do have with them is that they come out quite warm after a hard flight, however with LIPO technology where it is, this is to be expected. All in all a very good battery which we could not recommend highly enough.
Turnigy nano-tech. 65-130C
These have been around for the last couple years now. They are good for the price and it is a good base battery to start on especially if you are flying your quad 3S. For high Amp 4S flight we personally find that the C rating (which is much closer to 65 than 130) is not quite high enough and the voltage lag and subsequent puffing does begin to become an issue and the lower C versions of this battery are not a really feasible for miniquads. The biggest issue with these batteries is the short life span almost all the ones we have are puffed now and out 6 4S batteries bought in the last 6 months 3 have a dead cell. One other issue to look out for is the weak soldering pads which have a tendency to rip easily if your battery is poorly mounted on your quad. But despite these issues we do recommend them for beginner to medium fliers and especially for those fliers who don’t push their quads too far.
SMC True Spec 1300mAh 4S 37A:
SMC are new to the miniquad market, but they have been in the RC Car industry for a while now. Reports of these lipos are excellent, and we are very impressed by their punch out performance especially near the end of the pack. Pilot Mr Steele is also said to be a fan. A unique feature of these lipos is that they steer away from the C rating that most of the industry uses. These are hugely inflated for the vast majority of lipos out there and there is no industry standard for how to measure the C rating! So manufacturers can simply put any number they wish! However SMC are trying to change this and have a rigorous testing procedure to determine the “true” C rating of a pack.
Tattu 1800mah 4s
Tattu, as well as its sister company Gens Ace, produce high quality lipos for not only for our application of miniquads but also for large hover ships used for Aerial Photography. These batteries are available in a wider range of capacities than most brands and cell counts, from 3s to 6s (for those of you who are crazy), and 1000 to 2200mAh. Most people think that these batteries perform well, especially the 75C rated packs. However like most high end packs these don’t come cheap, with a 1300mAh 4S 75C coming in at €35.99!
Turnigy Graphene 4S
Though still new and not fully tested the Turnigy Graphenes have been getting some positive feed back from the community, many pilots are finding the Graphenes are cooler after a flight and they seem to have quite good life spans (however they haven’t been out for long enough for us to be sure). They have also been measuring very low resistance rates, sometimes as low as 1.2Ohms (3 Ohms is average for a new lipo). They also have been shown to maintain very respectable discharge rates as well as extremely high charge rates, Hobbyking quote as high as 15C (though we wouldn’t recommend this). The only issue with the Turnigy Graphenes is the weight the 1500mah is 208g compared to the Dronelab’s equivalent 159g.
