Just purchased this before realising they offer an mains version...   https://hobbyking.com/en_us/imax-b6-50w-5a-charger-discharger-1-6-cells-genuine.html   just looking for some links to adapters to use with this charger so I can plug it into the wall?   plenty on the search but a lot of out of date links and advice. Some people say a connector needs to be soldered on, is this correct?   many thanks
