A few months ago I bought a Winmax battery on ebay as it was fairly cheap. When I received it, I found that the resistance in the cells were very low and it performed just as good if not better than my other batteries.(Turnigys and Nanos)
I have just received 2x 4s 4200 Winmax 50-100c lipos from Leaderhobby which I will be testing and comparing against Hyperion's 4s 4200 45-90c packs
Areas of testing will be...
Performance - Top Speed, Voltage Drop.
Resistance Before use and after 5, 10, 15 cycles etc.
Run Time
Cell Balancing
and I will also be using an Eagle Tree Data Logger
Price difference
Winmax 4s 4200mah 50-100c- $42.83 each
Hyperion 4s 42000mah 45-90c- $125.95 each
Just going to get my 5.5mm bullets soldered on and then I can check the resistance
Here's how they came
