I have two 2s 2200mah batteries laying around for my mini e-revo. I'm mostly doing 1-2 hours trails with my bronco and would like to use the battery tray in the front for a bit better weight distribution. Should I pick up a parallel connector for my 2s? Or just get a new single battery for the front tray. I could just run one battery at the time, but I'd rather have some more capacity. Both the 2s fit at the same time in the front tray which is rather neat.
