    What dual batteries are you running with the extended battery holder?

    I installed my system, and the only packs i have that fit are duratrax 3s.....
    I wanted to run 2-2s batteries, but my hardpacks dont fit.....
    wondering what you guys are running?
    Thanks

    I have been runnig 2 2s gens ace 5000mah packs. I have the tall hold down but theres not enough room. I just put one pack under and zip tie another to the top. It holds them unless I have some kind of crazy major crash, I would recommend only doing this with hard case lipos though.

    You could use a velcro strap to hold the packs in, and you could charge 2-2s packs in parallel with your charger, it would just take longer.
