For once I did not use my 2.8 volt cutoff, but discharged down to 2 volt (This is the lower limit for these batteries).












The battery has no problem delivering 20A.















Conclusion

The battery can be discharged down to 2 volt, but the voltage does compare favorable to other LiIon batteries with a higher end voltage. Using a cell from LG I will call this a very good high current battery.
