This cable makes very easy to charge your lipos, no need to use and carry around the balance board anymore. Also it reduces resistance and help balance charge you battery better, since, at least for me this cable goes directly from my SkyRC charger to my battery, no need to use anything else that would increase resistance. Good quality cables and gold plated terminals.
This lead pack makes charging LiPo's so much easier. The leads are long enough so that you can charge your batteries inside a LiPo safe bag without needing any other leads. (I have 4 of these to go with my Quattro charger.)
