So I got a batch of TP4056 based USB chargers (hopefully, the pinout did match but there was no print on the ICs) which unfortunatly overcharge the cells to somewhere between 4.22 to 4.30 V. Not good. Will replace the ICs.
Anywho, my four different Lii-500 chargers all reported 10 mohm IR for each overcharged cell. Seems to bottom out at 10 mohm. Highly unlikley that all cells would have that low IR.
Has anyone else observed this phenomonon?
