I have had one of these chargers for a few months now and find it very handy as it can charge Li-po and normal batteries and has made it a lot less hassle as instead of carrying 2 to 3 chargers I now carry one which charges my normal 8.4v 3700mAh, 9.6v 5000 mAh, 7.2v 2200 25c Li-po, 11.1 2200 25c li-po batteries and my Battle Axe magazine battery. This device is smart and easy to use and comes with very easy to follow instructions which I recommend reading before using.
