Recently started racing 1/12 scale on carpet, with 1S batteries - I have been charging using my I-Charger and normal 2S charge cable, but I have been told 1S batteries would charge faster using a 1S cable.

True?

It looks like the balance lead just goes to the positive plug on the battery - if so, can I just add a female plug to the + plug and plug in the balance lead when I charge 1S?

Thanks
