I got these batteries with a charger.









There is significant difference between the two 0.1A curves, probably because the battery has been in storage for a long time.
Generally the tracking between cells are less than perfect and high current are not that good either.















Conclusion

The performance is not in top, but I wonder if it because I got old batteries or because Evolta are not that good.
