Test/review of Charger Xtar MC4 update
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. Here is an explanation on how I did the above charge curves: How do I test a charger
