    This is a high current battery and as usual for this type of battery the capacity is at the low end.

    There is good match between the two cells and they has constant capacity up to about 20A, this is good. The max rating of 30A is probably only for pulse load.

    Conclusion

    This battery is designed for high current and has a good performance up to 20A, below 10A there are batteries with more capacity.
    I will rate it as acceptable.
