High capacity 18350 with protection circuit.










The two cells do not match in capacity, because it is protected cell they can still be used in series.















The protection is higher than 7A, I will guess at around 8 to 9A, as can be seen in my test one protection tripped during a 7A discharge and they both tripped immediately when I tried a 10A discharge.







Conclusion

I am not really happy about these batteries, capacity is a bit low and they are different, but then they are much better than many of the old generation 18350 (<=700mAh types) and they are protected.
