Delivery 16 days to the UK Externally as described. 3.35V as received. Charged to 4.2V in 40 mins @ 300mA,. Would expect to take 2-3 hours for 600mAh Will do more testing... Other products from PK have been good, had hoped these would be too.
My mistake, these are lithium iron phosphate cells with nominal voltage of 3.2V, max charge to 3.6V ( Vs STD LiIon 3.6V, max charge to 4.2V ) Capacity appears to be close to the stated 600mAh
Parcel took a month to arrive to belgium, I guess this is due to covid, it arrived well packed, I’m still testing them, will probably add a comment later on but so far so good.
