    Testing of the 1800mAh LiPo's is done and I probably won't be adding any others to the list for at least a couple of months. I'll be catching up on some round cell testing and then the 2250mAh LiPo's hopefully some time in April-May.

    Here is the graph directly comparing the performance, at 20A continuous, of all the 1800mAh LiPo packs I tested. I've also included a table of the maximum temperatures measured during a 20A continuous discharge.

    The Turnigy Graphene 65C is the best performer with the Turnigy Nano-Tech 65C-130C close behind. The MaxAmps 100C is clearly the worst performer.

    The table of temperatures echoes what is seen in the graphs, with the the Turnigy Graphene 65C and Turnigy Nano-Tech 65C-130C having the lowest operating temperatures and the MaxAmps 100C having the highest temperature.

    The 22°C spread between the hottest and coolest running packs at 20A continuous is huge and reflects the large differences in internal resistances between some of these packs.

    It is the internal resistance of the cells that determines both the voltage sag and the amount of heat produced during a discharge. The cells with the lowest internal resistance will produce the least heat and be the best performers, running at the highest voltage.

    As seen in the discharge graph and the temperatures table, a couple of the other packs still performed well. If their prices are lower than the top performers that could make them packs you should consider if money is tight.

    Be aware of the sizes of each of these packs though! The Turnigy Graphene is larger than all the other packs. The MaxAmps is the smallest.

    wow, turnigy for the win, who saw that one coming?
    Thanks mooch, I was going to builda mod this winter but really wanted the piece of mind of your testing first. Since I build a mod around a battery and not the other way around, I'm glad I waited.
