This is the latest generation of Dronelabs batteries, the Evolved series, and it is indeed a evolution of the older packs.
The performance is really good in the 1500mAh lineup at a very fair price. They don't use the smallest and lightest cells, so there probably shouldn't be any problems with the lifespan either. They do not have the C rating on the packs, they do write the amps on the batteries. In this case, there is a 160A on the label, but they do claim 95C on the website.
And there is something special here: They do claim: "New Cell Internal Resistance: 3.7mOhm +/-10% @ 27*C". This is outstanding! They tell us the temparature beside the IR. So absolutly no marketing here at the IR. In fact, my cell was well in the range they do claim!
The 190g weight is not the lightest pack out there, but it is in part because of the longer battery and balancer cable, and of cource because of the bigger cells.
This battery is truely a Evolution in the Dronelab lineup, and hitting the ranking at a strong 1st place, in the 1500mAh class, (just behind the R-Line 1550mAh) at the time of the test!
