Do not expect 7000 mAh from 32700 type size for LiFePo4 (is is impossible) so let's do some tests. Measured weight is about 143 g (with nickel strips). Measured internal resistance for all batteries with true AC 1kHz method is between 6.6 - 6.8 mOhms. Measured full capacity for one random cell is about 5600 mAh. Measured capacity with discharge current 10A to 2.55V is 5000 mAh. I also discharged the battery by 15A current, the temperatured rised to about 50°С (ambient temperature during tests is 27°C), so it is near a limit because you will get a temperature higher than recommended. By the way the welding for strips is rather weak, it is easy to detach strips (one point is detached during tests).
