I only assumed they were designed to solder direct to the cells as this is show in the official example provided by novak.

The battery came with Tamiya style connectors so I do not image that they would provide too much power to melt the connectors in this case however it is only a basic 3300 mAh Ni-HM battery (

Most of the batteries on vapextech come with Tamiya 2-pin & Futaba connectors. How high do you mean when you say higher currents and do you suggest replacing all the connectors then?
Thanks
