EDWARD2003... We haven't received your GP3700 pack yet.
Team Duratrax... The IP3800 cells are different than IB3600s, IB3800s and GP3700s.
So far, we are very happy with the performance of the IP cells. And we are convinced that the IP3800 is currently the best cell in stock/19T racing because of the extremely low IR. This is our opinion. And I know that they are working very hard to improve the cells, so the IP3800s are getting better and better. The recent batches of cells have more runtime. And actually, from the last shipment we just received, the runtime is now getting close to the IB's.
