Charger Xtar MC4 update

Review of MC4, read this first



This is a fairly small 4 slot charger from Xtar with usb power input. It can only charge LiIon batteries.




This review will only be an update, not a full review.




Measurements



A normal charge curve, it looks the same as the first review.



With a 0.5ohm resistor in series (i.e. a weak power supply or a long cable) the charger over charged the batteries, the updated version do not over charger, in this case the charge voltage is a bit low (Within the allowed +/- 0.05V).



I tried one test more, this time with a 1ohm resistor, i.e. even worse cable and the charging was perfect.



The orginal test was with 4 cells in the charger and it also looks fine in that case.



Conclusion

This means I will give the charger a good rating.



Notes

The charger was supplied by a Xtar for review.
