Well, my Liitokala 300 just arrived.
All four Trustfire Flames 3000mAh report an IR of around 50-100mR
…but with batteries fully charged, it will go to “null” in both slots, which I believe means that the batteries’ protection is kicking in because of the slightly high termination current… or that’s what I thought!
So I measured the voltage with no batteries in the charger… and it’s 4.9V in both slots!!!
What gives? Isn’t that insanely high?
EDIT: Also, while charging an almost full battery, the voltage oscillates between 4.16V and 4.23V in 15-20 secs intervals. Is that normal?
EDIT2: Once the protection is trigered, the battery measures only 4.13V. With the cheap charger it went up to 4.17V
EDIT3: Found this so I guess it’s normal for these batteries to trip the protection.
