LiitoKala has updated the wrapper for their battery, is the battery inside still the same?





Performance looks good up to 15A-20A



The cell got very hot at 30A, this is too much for continuous discharge.






Conclusion
The performance is slightly below the old version, but it is still a very good performance.
