Orca 4000 20C lipo review Part 2

After 4 runs on the Orca 4000mAh 20C lipo, I feel its crap! The punch is really poor but it did feel that it last longer. Anyway, I want more PUNCH in the lipo. Honestly, I dont think the pack is 20C at all. Even my Yeah Racing 3200 20C gives better punch than the Orca. Should have stick to Yeah lipos all the way...
