The standard battery retainer doesn't allow you to use side by side hump packs, it only lets you use stick style hump packs... So what would be the best way to mount a side by side hump pack into the Slash? If anyone has done something, can you post a picture? I'm going to order some batteries from SPC here shortly, and am trying to get ideas on how to mount them. I would normally just get a 7-cell flat pack and not worry about it, but I wanted to use the batteries in my Stampede too though. So anyone have any ideas?
