It is still too early to decide if new Turnigy Graphene are worth the money, but after 3 flying weekends with them I do have some thoughts about them already.
- They discharge differently than Turnigy Nano-Tech I'm using in parallel. Discharge curve seems to be flatter
- Voltage drop on high load is much smaller comparing to Nano-Tech. Also, they do not regain voltage when disconnected. I usually try to fly until voltage goes below 3.5V per cell. More less 4:30 up to 5 minutes of flight with my regular style. Before charge Nano-tech's voltage usually goes up to 3.7V. With Graphene, it's different story. Before charge voltage per cell is around 3.65V. Maybe it's only half volt, but does tell something about discharge curve and general battery performance
- Althought they behave different than Nano-techs, they both accept more less the same charge during load
- My Graphenes are new, while Nano-techs not, but Graphenes seems to balance faster. Looks like cells are a better match. I still would have to confirm this
- They are indeed quite heavy, but I did not noticed lower flight times or worse performance
