I just finished charging a couple sets of 18650 batteries on this new to me charger. EagleTac 3100’s came off at 4.23 and 3100 Callie Customs came off at 4.25. This is a little higher than my other olde 2 chanel chargers where my batteries consistantly come off at 4.20 to 4.21. Anyone see a proublem here? I just bought a new multimeter that I used to test these as I’m away from home and my old multimeter. Maybe this new multimeter is just reading slightly higher.
Let them rest and test again.
i am buying my 3rd i4. both terminated at 4.200 (4.196-4.203). will report
And keep in mindd 4.25 volts is within specifications for these batteries.
I've reported in other threads that my i4 is charging to 4.28v, however I've discovered something is wrong with my meter reading tailcap currents too high and I don't have another trustworthy meter. Two other meters I have (one is an old analog) did show higher than 4.25v. The voltage of the cells did not drop and the charger did overcharge a completely different cell on a second try.
See this thread.

Thanks for the quick responses. I charged these batteries yesterday and tested them again today so they have rested.
I know that 4.25 is within spec but I have read that it’s better for the batteries if they aren’t charged that high. I noticed something else. I checked the voltage of the batteries when the last light started blinking on the charger and found the batteries at 4.15. If I leave them in until the lights stop blinking, it takes more than 1.5 hours to get that last .08 to .10 of extra charge. Maybe not worth the extra time and wear on the batteries.
Mine stops different batteries on different voltages…but no one higher than 4.21V.
But it charges them to noticeable more Voltage than my turnigy hobby charger.
Fasttech sells all sorts of battery holders

The problem with the battery holders is that they are tight, especially when you put a protected Panasonic or so in them which are almost 70mm.
I normally use a standard cradle made from a single bay charger and a standard 12v 3A power supply which was about 10$ or so. I also have a 2 18650 cradle with a balancer plug, but I don’t like it because its so tight and because I don’t get the capacity from each cell separately just one capacity is displayed.
I made a magnet adapter as well, but I like the cradle more especially as some cells aren’t magnetic.
I like the turnigy charger very much because you get a feeling for the capacity. If I charge a battery and it was still half full then I know the next time I can play a bit longer. And of course I can charge my 16340 with little current and my 26650 with high current.
If I would buy a charger again I would go for a higher power version, not because of the charge but because of the discharge abilities. The 50W Version is only able to do discharges at 1A.
