The 7000mAh s a bit optimistic, but it is definitely 6000mA and discharge current do not really matter. The cells do not matches perfectly.

Conclusion

As usual with LiFePO4 the output voltage is fairly stable during discharge and with 6000mAh there is a fair capacity in the battery and this is also the case at 30A.
